Certificate of authenticity
Diamond jewelry comes with documentation of the stone’s key characteristics.
Authenticity & Certification
Every diamond, documented.
Beauty you can see — and proof you can hold. Each piece is accompanied by the details that confirm exactly what you own.
Authenticity, guaranteed
Four checks stand behind every diamond and fine jewelry piece we sell.
Hallmarked metal
Gold and platinum are stamped for purity, so the metal is exactly as described.
Independent grading
Larger center stones can be supplied with a report from a recognized gem laboratory.
Verified at handover
We check your certificate details against the piece with you before it leaves our hands.
