Built in Detroit. Worn Everywhere. Free Shipping Over $99.

Detroit built this. You're about to wear it.

Twelfth XII isn't a jewelry drop. It's a standard — built on a Detroit street, worn by people who know real from fake across a room. Every piece carries two things at once: the city that made it, and the person who earns it. No blood diamonds. No shortcuts. Just stones that shine clean and a name that means something when you say it out loud. This is #TwelfthIsWealth. Welcome in.

Why Our Stones

Brilliance shouldn't cost someone else their freedom. We will never sell a blood diamond. Every stone in every Twelfth XII piece is lab-created — VVS moissanite and CVD diamonds, fully traceable, conflict-free from source to setting. No mines. No exploitation. No oppression buried in the sparkle. Just stones that are genuinely brilliant, genuinely durable, and genuinely clean — because luxury isn't luxury if someone else paid for it in a way you'd never say out loud. That's not a compromise. That's the whole standard.

Who We Build For

Built for the ones who came up — not the ones who were handed it. Twelfth XII is for people who understand that real wealth isn't loud, it's earned. The ones who know the difference between a piece that's just gold-colored and a piece that's actually built right. The ones who wear their come-up instead of hiding it. You don't need old money to have taste. You need standards. That's who we make this for.

Home of the Trendsetters.

Detroit invented the fit before it had a name — and around here, the outfit was never finished until the jewelry landed right. Heavyweight tees for the fit. Real gold, real stones, real standard for the finish. That's how Detroit gets dressed.
