The examination

Dia-Script

Laser inscription on the girdle — the report number and logo, or a personal message. Match the stone to its report at a glance. A safe, risk-free procedure.

Diamond Seal

The stone sealed inside a tamper-evident transparent capsule. It cannot be opened without leaving evidence — proof the diamond inside is the diamond we examined.
