Quality you can verify.
Not a logo you pay for.
Full eternity rings set with natural D–F diamonds of FL–VVS2 clarity — crafted individually by Japanese goldsmiths, with a GIA certificate accompanying every ring. You pay for the stone and the hand. Nothing else.
One ring, made to a standard that doesn't compromise.
LYNN makes one thing exceptionally well — the full eternity ring. A continuous line of matched natural diamonds, each meeting the same uncompromising specification. No secondary tiers, no hidden trade-offs.
Discover Royal Flower→Every figure of the specification, explained — before you spend.
A recognizable name can add 40% to a price and nothing to the stone. We show you the specification and let the diamond justify itself.
Made by hand, in Japan, without haste.
Each LYNN piece is produced with skilled Japanese goldsmiths whose discipline defines our standard. From proportion to final polish, every stage is completed by hand and by eye. Nothing is mass-produced; the maker's full attention belongs to your ring alone.

Enquire About a RingBorn from a moment worth keeping.
LYNN is a Tokyo-based fine jewelry house founded from a single, personal moment — and built to create jewelry worthy of life's defining ones. Each piece is made to order, shaped with discipline, patience, and emotional depth.
Memory, refined into form.
LYNN began when our founder set out to create something meaningful for his wife after the birth of their son — not simply a gift, but an expression of gratitude, strength, and a love that had deepened. Searching for something truly worthy of that moment and finding the process distant, he chose to create it himself: overseeing the stone, the sourcing, and the craftsmanship so the piece carried sincerity in every detail.
From that conviction, LYNN was established — on the belief that jewelry is more than adornment. It becomes a keeper of memory, holding a moment in time and carrying it forward. Each ring is crafted individually in Japan and made to order, so that it may one day hold a story of its own.
Every piece is created for a meaningful moment — shaped with discipline, patience, and emotional depth.
From stone selection and sourcing to final finishing, every decision is guided by hand — and documented independently by GIA.
Crafted individually in Japan, never mass-produced — a keeper of memory built to last beyond a lifetime.
Meet the ring we make.
LYNN began with a moment we will never forget.
After the birth of our son, I wanted to create something meaningful for my wife — a piece that could quietly hold the weight of that chapter in our lives. It was not simply a gift, but an expression of gratitude, strength, and the love that had deepened between us.
I searched for something worthy of that moment. What I longed for was purity in quality, balance in design, and intention in every detail. Yet within the world of large retail houses, I sensed that much of what defines true craftsmanship — careful stone selection, thoughtful construction, and uncompromised finishing — was often shaped by scale rather than intimacy. The process felt distant, and there was little space to guide the details that mattered most to me.
So I chose to create it myself.
From selecting the diamond to refining the structure of the setting, every decision was made with patience and devotion. I wanted to oversee the stone quality, the sourcing, and the craftsmanship — not in pursuit of perfection alone, but to ensure the piece carried sincerity in every detail. She deserved nothing less.
When she received it, we understood something lasting. Jewelry is more than adornment. It becomes a keeper of memory. It holds a moment in time and allows it to live beyond the day it was created. That piece did not only mark the birth of our son — it preserved the emotion of that chapter, quietly carrying our story forward.
And in that realization, something shifted. We began to see that what felt extraordinary to us was not unique in desire. Everyone longs to honor a meaningful moment — whether for a partner, a family member, or even for oneself. A birth. A promise. A personal milestone. A quiet triumph.
When a piece is created with intention for someone special, it becomes more than a gift. It becomes part of a story that moves through time — carried, remembered, and passed from one generation to the next.
From that conviction, LYNN was established.
What began as an intimate expression of love evolved into a commitment: to create jewelry worthy of life's defining moments. Each piece is made-to-order, shaped with discipline, patience, and emotional depth — so that it may one day hold a story of its own.
As LYNN continues to grow, our vision extends beyond fine jewelry toward the artistry of high jewelry — where craftsmanship remains uncompromised and beauty is shaped with enduring intention.
Because true luxury is not excess. It is memory, refined into form — and made to last beyond a lifetime.About the house→
The hand is the standard.
In Japan, craft is a discipline of repetition and restraint. The goldsmiths who make LYNN rings have spent decades doing the same exacting work every day — which is precisely why we trust them with yours.
Decades of discipline, in a single pair of hands.
In Japan, mastery is measured in decades, not deadlines. The goldsmiths who make LYNN rings trained for years before they were trusted to set a single stone — and they have set thousands since. Their hands carry a precision that no machine reproduces and no shortcut earns.
This is the quiet advantage behind every LYNN piece: not a factory line, but a craftsman who gives your ring their whole attention, from the first stone to the final polish.
Machines can repeat a shape. Only a hand can judge when it is right.
A diamond, set by hand.
No two stones sit exactly alike. Each is seated, aligned, and secured by eye — a few grams of precious metal and a lifetime of judgment.
From deposit to delivery, without ambiguity.
Your ring does not exist until you order it. Here is exactly what happens after you do — and what you approve at every stage.
Please note: once your Final Production Sheet is signed and production begins, an order cannot be cancelled — each ring is made individually to your specification.
Four figures tell you almost everything.
The Gemological Institute of America grades diamonds independently — it sells nothing and answers to no brand. These are the four figures of LYNN's specification that carry your money, and what each one means.
Graded from D downward against master stones. D–F is the colorless range — no visible tint, even set side by side in a full circle.
From flawless to very, very slightly included — characteristics so minor a trained grader needs 10× magnification to find them.
For Asscher and Marquise cuts, GIA grades polish and symmetry rather than an overall cut grade — the figures that decide how completely the stone returns light.
Some diamonds glow under UV light, which can dull their appearance in daylight. Ours show none, or a faint trace with no visible effect.
How verification works at LYNN: on designs with a center stone, the center diamond carries its own individual GIA grading report, and its report number is written onto your Final Production Sheet. The smaller diamonds of the band are independently screened for natural origin before setting and matched by us to the specification above — and your finished ring ships with its GIA certificate, reviewed by you before the balance is due.
Ask us anything about a certificate→Size once, correctly.
A full eternity ring is set with diamonds around its entire circumference — so it cannot be resized after it is made. Getting the size right the first time matters more here than with an ordinary band. Most clients simply measure at home and give us their size from the chart below; if you are at all unsure, we will send a complimentary sizing kit before anything is made. Either way, production begins only once you have confirmed your exact size in writing and signed for it.
US size chart
Inside diameter, measured edge to edge — measure a ring that already fits the right finger well, or the finger itself. Half and quarter sizes are available on request.
Fingers change with temperature and time of day — measure in the evening, at room temperature, for the truest reading.
Wider bands wear more snugly than thin ones. If you fall between sizes, we'll usually recommend the larger — and confirm it with you first.
Unsure between two sizes? Write to us before ordering — sizing questions cost nothing, and remaking a full eternity ring is not possible.
Made individually for you, and stood behind where it is ours to stand behind.
Every LYNN ring is crafted to order once your size is confirmed, so each piece is a final sale. Where a fault is genuinely ours, we repair or replace it — insured shipping included, both ways. Here is precisely how that works.
Why every order is final
A LYNN ring is not taken from a shelf. Each piece is manufactured individually in our Tokyo atelier once payment is confirmed and your size is signed off, and a full-eternity band cannot be resized once set. For this reason all sales are final: once production is scheduled, an order cannot be cancelled, modified, returned, or refunded, except in the case of a verified manufacturing defect.
The Sizing Protocol
Because a final sale leaves no room for a fitting mistake, we settle size before anything is made. Most clients measure at home using our sizing chart; if there is any doubt, we send a complimentary sizing kit at no charge. Production is scheduled only once you have confirmed that size and signed the Final Production Sheet — so fit is settled, in writing, before the first stone is set.
Every order ships fully insured. If a piece is damaged in transit, notify us within 7 days of delivery with photographs of the outer packaging, the inner packaging, and the item as it arrived, so we can file the carrier claim.
A verified manufacturing defect caused by us is repaired or replaced at our cost, including insured shipping both ways. Claims must reach us within 14 days of delivery with clear photographs; after that window the piece is considered accepted as delivered.
A structural or craftsmanship fault that materially affects the integrity of the piece — a stone that loosens or falls from its setting under normal wear, a structural fault in the band, or a finishing flaw present at delivery.
Change of mind, personal taste, or an incorrect size chosen after our Sizing Protocol. Natural gemstone inclusions, minor surface marks consistent with handcrafted jewelry, dimensional tolerances within industry standards, variations from lighting or screen display, and normal wear and tear.
Our remedy, and the years after
For a verified defect, the remedy is repair or replacement at our discretion; refunds are not issued. Beyond that, a LYNN ring should be worn for decades, and we remain responsible for it — write to us with photographs and we will assess any later repair honestly and quote it fairly. A manufacturing fault remains ours to fix, whenever it surfaces. Nothing here limits any rights you may have under mandatory consumer-protection law.
The finer points
A cancellation request may be considered only before production is scheduled. If you cancel before signing the Final Production Sheet, your 50% deposit is refunded, less the cost of the complimentary sizing kit and any non-refundable payment-processing fees. Once the Final Production Sheet is signed and production has begun, the deposit becomes non-refundable and the order cannot be cancelled for any reason.
Each piece is made to the specifications shown on its product page and your signed Final Production Sheet — materials, dimensions, total carat weight, design details, and verified size. Once signed, those specifications are final.
Any import duties or taxes levied by the destination country are the buyer's responsibility. Orders that are refused, unclaimed, or returned for unpaid duties are not eligible for refund, and any carrier or storage charges incurred may be deducted from any eligible amount.
Please contact us first, and we will work to resolve any concern. A chargeback raised after production has begun or delivery is confirmed will be formally contested with your signed Final Production Sheet, production records, and carrier confirmation.
Email info@lynnfinejewelry.com with your order details and clear photographs of the issue, within the window above. We reply within two business days with instructions and, where a defect claim applies, a prepaid, insured shipping label.
Insured to your door, anywhere, at no cost.
Every LYNN shipment travels fully insured, worldwide, free of charge. From the moment your ring leaves the workshop until you sign for it, it is covered for its full value.
Every piece is made to order. Production takes approximately 12 weeks from the date your Final Production Sheet is signed and your deposit is confirmed, and may vary with design complexity and stone sourcing. Production is separate from shipping time.
Orders are placed on a 50/50 structure — a 50% deposit begins production, and the remaining 50% is settled before your ring is shipped.
Complimentary worldwide DHL Express shipping on every order, dispatched from our Tokyo atelier. Each shipment is:
- Fully insured for the full purchase value
- Signature required upon delivery
- Presented in our signature box, in discreet outer packaging
Once your order ships from Tokyo, you receive a confirmation email with tracking, so you can follow it every step to your door.

Transit times are estimates and not guaranteed; they may shift with customs, routing, or weather beyond our control.
International orders may incur import duties or taxes set by the destination country; these are the customer's responsibility. We declare the full purchase value and never under-declare a shipment.
Please provide a complete, accurate shipping address — reshipment for an address error may carry an additional fee. Every shipment is fully insured in transit; if a parcel is lost before delivery, we assist fully with the carrier claim, and any transit damage should be reported within 7 days of delivery under our Returns & Repairs policy. Once the carrier marks the parcel delivered, risk of loss passes to you.

What we collect
Only what you give us: your name, email address, correspondence, and — if you order — your shipping address, ring specification, and payment confirmation details. This website stores nothing about you; the enquiry form composes an email in your own mail client.
How we use it
To answer your enquiries, fulfill your order, arrange insured shipping, and honor the warranty. If you subscribe to our newsletter, we use your email address to send it — and stop the moment you ask.
What we never do
We do not sell, rent, or trade your personal information. We do not share it for advertising. A house built on transparency about diamonds is not going to be opaque about your data.
Who else touches it
Only the partners required to deliver your ring: the shipping carrier and the insurer, who receive the minimum needed to move and cover your shipment. Each is bound to use it for that purpose alone.
Retention
We keep order records for as long as the law requires and as long as we remain responsible for your ring. Correspondence that leads nowhere is deleted in the ordinary course.
Your rights
Ask us at any time what we hold about you, ask us to correct it, or ask us to delete it — subject to records we must keep by law. Write to info@lynnfinejewelry.com and we will respond within two business days.

All LYNN pieces are made-to-order. Once production has been scheduled, orders cannot be cancelled, modified, or refunded. Estimated production timelines are provided for reference only and are not guaranteed.

We make every effort to ensure product descriptions, specifications, and images are accurate. However:
- Slight variations may occur due to handcrafted production.
- Stone weights are approximate and may vary within industry tolerances.

For custom or modified designs requiring CAD rendering:
- Production will begin only after written CAD approval has been received.

- After approval, the design cannot be modified, cancelled, or refunded.
7. Pricing & Payment
All prices are listed in USD unless otherwise specified.
A 50% initial deposit is required before production begins. The remaining 50% final balance must be paid in full prior to shipment.

Chargebacks initiated after production has begun or after confirmed delivery will be formally contested with supporting documentation. We reserve the right to refuse future service to customers who initiate unjustified payment disputes.

These Terms are governed by and interpreted in accordance with the laws of Japan. Any disputes arising in connection with these Terms shall first be addressed through good faith negotiation. If resolution cannot be reached, disputes shall be submitted to the Tokyo District Court in Japan, which shall have exclusive jurisdiction.

Accessibility.
Considered purchases deserve a site everyone can consider. We want every visitor to be able to read, navigate, and enquire with ease.
Our commitment
We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA across this site, and we treat accessibility as ongoing work rather than a finished checkbox.
Measures we take
Text and background colors are chosen for readable contrast, on both light and dark sections.
Pages use semantic structure — real headings, labels on every form field, and link text that says where it goes.
The site is navigable by keyboard, and layouts reflow for small screens and magnification without loss of content.
Imagery is descriptive, not essential — nothing you need to know lives only inside a photograph.
Tell us where we fall short
If any part of this site is difficult for you to use, write to info@lynnfinejewelry.com. We respond within two business days, and we will also complete your enquiry or order by email directly if that is easier.
A few pieces.
Each one, everything.
LYNN makes only a small number of designs — each one perfected rather than multiplied. When a piece cannot be improved, it stays. When it can, it never leaves the workshop.
Royal Flower
A repeating diamond flower — four marquise petals with a step-cut Asscher between each bloom, hand-set in Pt950 platinum or 18K gold around the entire finger.

Enquire About a PieceRoyal Flower
Some rings mark a moment. This one carries it — a continuous ring of light with no beginning and no end, shaped into a quiet flower that never fades.
Royal Flower is for the person who wants their most important piece to say everything without saying anything at all.
A flower, repeated. One unbroken garland.
Royal Flower is a full-eternity wide band built from a single motif, repeated. Each bloom is four Marquise-cut diamonds arranged as petals; between every flower sits a step-cut Asscher diamond set on-point — architectural, still, and deep. The pattern runs in perfect symmetry around the entire finger, so from every angle the ring reads as a single, unbroken garland of light.
Hand-set in your choice of Pt950 platinum or solid 18K gold with a high-polish finish, it is bold in presence yet low enough to live on the hand every day.
One design. Two metals.
Royal Flower is cast to order in your choice of Pt950 platinum — naturally white, with no rhodium plating to wear away — or solid 18K gold in white, yellow, or rose. Your metal is confirmed together, in writing, before production begins.
What the eye is seeing, and why it matters.
Full eternity means diamonds all the way around. There is no "back" to this ring; light travels the entire circumference, so it shines from every angle, always.
Between each flower sits an Asscher-cut diamond set on-point — a step cut with clean, concentric lines that gives the eye a moment of calm between the petals, and joins one bloom to the next.
Four Marquise diamonds fan out to form each flower. Their pointed tips are held by refined V-prongs — a detail that both protects the delicate points and completes the floral silhouette.
A comfort-fit interior, soft rounded edges, and a deliberately low-to-medium profile mean Royal Flower is engineered for daily wear, not just display. Inside, engraved by laser: LYNN and your metal mark — Pt950 or 18K.
What "Excellent" does when the light arrives.
Brilliance is the white light a diamond returns to your eye; fire is the color that flashes at its edges as you move. Both are decided by how precisely the facets are cut and aligned — not by size, and not by name. Done poorly, light leaks out the back of the stone. Done excellently, it comes back to you.
A note of precision: GIA issues an overall cut grade only for round brilliants. Step cuts and fancy shapes — our Asschers and Marquises — are graded on polish and symmetry. On a Royal Flower, both must be Excellent. Same discipline, stated truthfully.
Presence you notice. Weight you forget.
At 5.8–6.0 mm wide, the band reads unmistakably from across a table — yet the low profile and comfort-fit interior let it slide under a glove and sit against its neighbors without catching. It wears like a ring you've had for years.
The proof, line by line.
The spec is the story.
Every Asscher and every Marquise is a natural diamond, matched by hand for color and light, set in solid Pt950 platinum or 18K gold — not plated, not filled. The same ring under a famous name would carry a markup for the box, not the stones. Here: verifiable diamonds, solid precious metal, Japanese hand-setting, and a GIA certificate with every ring.
