Gemworks is the first marketplace and certification system built to solve the gem industry’s oldest problem: trust. Using blockchain and AI together, we aim to deliver permanent, verifiable provenance for gems and jewelry — from ethical mine to finished piece. Every stone’s origin, craftsmanship, value, and story can now be proven, traded, and turned into a forever legacy.

One Marketplace. One Certificate. One Verifiable Story.

Gemworks is a simple, open marketplace where you can buy, sell, or auction certified gems and jewelry — but the real innovation lives inside the certificates themselves.

Every item on Gemworks is paired with a serialized, tradeable NFT certificate that evolves as the stone moves through the industry.

The Certificate Lifecycle

1. Source Certificate Creation (For Miners)
Verified miners can create and sell origin certificates (along with their mineral specimens or facet rough) that document:

• Mine and geographic source

• Ethical and sourcing details

• Photos, videos, or notes from discovery along with their company branding.

This solves one of the industry’s biggest challenges: verifiable ethical origin — which is a baseline for everything here at Gemworks.

2. Faceted, and Graded Gem Certificate Creation (For Cutters)
Verified cutters can chain source certificates into to their faceted gem certificates containing:

• Cut details and grading data

• Lab reports

• Optional: Gem appraisal values via Gemworks AI (more info below)

This stage finally gives true recognition and provenance to artisan cutters, whose craftsmanship is rarely documented or preserved.

3. Finished Jewelry Certificate Creation (For Jewelers)
Verified jewelers merge everything into a final certificate containing:

• Stone provenance and grading

• Details of the finished piece

• Any added jewelry appraisal certificates, for insurers

The result: a single, living certificate that proves the full journey of a piece — something the industry has never had before.

Provenance With a Human Story

Beyond technical data, Gemworks allows something far more meaningful: the story of creation.

At every stage — mining, cutting, setting — creators can add:

• Images

• Videos

• Written notes

Each finished piece carries a discoverable narrative of how it came to exist, not just what it weighs or grades.

This is provenance made human.

The Gemworks Momento Card™

Sentiment, That Lives Forever

For finished jewelry pieces, Gemworks introduces something entirely new:

The Momento Card.

Anyone holding the final certificate can add personal, private media before gifting:

• Love stories

• Proposals

• Anniversaries

• Celebrations

• Heirloom histories

Photos, videos, audio, documents — all sealed into the final Jewelry certificate — paired with an optional physical card that comes with a prive key laser etched into stainless steel that’ll allow access to the content today, tomorrow, or 10,000 years fromnow.

Cards fade. And are ultimately lost.
But Momento’s live on forever, permanently tied to the physical piece.

Not every gift is a diamond — but now, any piece of jewelry can be a gift that lasts forever.

All this for the price of a premium store-bought greeting card.

(Jewelers will receive special reseller pricing on all Momento Addons & physical Momento Cards.)

Certificates That Come With the Tools Jewelers Actually Need

The global gem appraisal industry is a $1.8B market, and today it’s slow, expensive, and inefficient.

Cutters and jewelers already know their stones — what they don’t always know is (or have handy, at an affordable rate) are:

• Current global market prices

• Wholesale vs retail replacement values

• The ability to offer – and quickly create – insurer-ready documentation that stays with each piece forever

Gemworks Gem Appraisal AI

During certificate creation, verified cutters and jewelers can:

• Instantly generate Retail Replacement Value

• Instantly generate Wholesale Cash Value

• Add both directly into the certificate with one click

No more expensive subscriptions.
No quarterly pricing books.
No wasted time.

A Fee-less Marketplace, With Built-In Protection

GemWorks operates a 0% trading fee marketplace made up of:

• Verified miners

• Verified cutters

• Verified Wholesalers

• Verified Jewelers

• Collectors, Buyers & Consumers

Smart-contract escrow ensures:

• Funds and certificates move safely

• No one gets ripped off

• Physical items and digital records stay in sync

Certificates and physical items can be bought, sold, auctioned or traded at any stage — rough, cut, or finished.

Serialized, Tradeable, and Forever

Every certificate is:

• Serialized

• Tradeable

• Permanently stored on-chain

Ownership transfers cleanly.
Provenance never breaks.
History cannot be altered.

The final holder may overwrite (or add to…) only the personal Momento portion, allowing each generation to add its own chapter — without erasing the past, while also allowing the holder of a Jewelry piece, the ability to erase a Momento, before the sale of any piece.

Powered by Blockchain, AI — and the Forever Coin

All marketplace activity, tooling usage and subscription transactions are settled in the Forever Coin. Without it, we wouldn’t be able to provide a fee-less marketplace.

Blockchain provides permanence and trust.
AI provides speed, pricing intelligence, and tooling.

Together, they finally modernize an industry that’s needed it for decades.

Create the History. Then Own It.

What you create is timeless.
And now, infinite.

Gemworks transforms gems and jewelry into living, explorable records — ethically transparent, economically fair, and emotionally meaningful.

Create the history.
Then own it.

Forever.
