About·MyPiece

An atlas of where jewellery is made and traded.

MyPiece maps the world's great jewellery districts — the historic streets, souks, and exchanges where stones are cut, gold is worked, and the trade actually happens — and explains them, plainly and from the source.

It started from a simple frustration: jewellery is everywhere online, but it's hard to know where any of it actually comes from, or who to trust. The places that have answered that question for centuries already exist — Antwerp for diamonds, Ginza for pearls, Jaipur for coloured stones — but no one had mapped them as what they are: a single, connected geography of the trade.

MyPiece starts with that atlas and connects it to free reference, buying, hallmark, birthstone, shelf, and editorial guides. Each surface answers a different part of the same question: what is this piece, where did its materials and craft travel, and what should you verify next?

Who it is for

A reference for the jewellery-curious

MyPiece is for people researching a jewellery district, preparing to buy or travel, learning how stones and metals are worked and marked, or caring for a piece they already own. No trade background is assumed; the information is written to help a reader understand the subject and reach the right next source.

The Atlas

19 districts, 15 countries

Each one mapped and explained — what it's known for, who shaped it, and what you'd actually find there.

Field Notes

10 practical guides

The useful stuff: buying with confidence, understanding the 4Cs, caring for what you own.

Where it's going

The longer ambition

The aim, over time, is to make the world's jewellery trade legible — to connect the places to the makers, houses, and craft that define them, so anyone can trace a piece back to where it comes from. We're starting with the districts because that's the map everything else hangs on. The rest we'll add only when we can do it properly and from the source — never as filler.

How we work

What we hold to

Sourced, not invented

Every district is researched from its own local and official record — trade bodies, museums, local press — and we keep the references. Where we can't verify something, we leave it out.

Craftsmanship

These places exist because of skill: cutting, setting, casting, the slow accumulation of a trade. We try to write about them with the same care.

Plainly useful

No login, no upsell, no dark patterns. Read what you came for and go — whether that's understanding Ginza or knowing your ring size.

Who makes it

Built by A Troy Ounce

MyPiece is made by A Troy Ounce (ATO), a small studio building things for the jewellery world. Another ATO project is SharkFin, a more playful take on how people discover and engage with pieces.
