Every diamond, certified and tracked.
Each piece carries its GIA or IGI certificate and a QR tag — and one tap issues an official AGA appraisal. Your case is always accounted for.
The right price, instantly.
Pick the 4C and the metal at the counter; maca computes the price from your own rules. No mental math, no underselling.
Take any payment. Stay audit-proof.
Card, wire, ACH or installments — with IRS Form 8300, KYC and AML handled right in the sale, not bolted on after.
A passport on every jewel.
Every sale ships a digital passport — proof of authenticity, warranty and certificate the buyer keeps in their phone. The relationship comes back to you.
