Authenticity & provenance

Every stone in the STONZA catalogue is verified through GGI Verification Center, Pakistan before it's listed for sale. We publish what we know about each piece — origin, treatment, and cut — directly on its product page, rather than leaving buyers to guess.

What we disclose on every product

• Stone origin and type
• Treatment status (natural, stabilized, or otherwise treated)
• Cut, clarity, and carat weight where applicable
• Metal composition — we state plainly when a piece is solid 925 sterling silver versus gold-plated, and never describe plated pieces as solid gold

Certificate details

Certificate information is available on each product page or on request via WhatsApp. If a product page doesn't yet show a certificate number, message us directly and we'll provide it.
