Title and body
AIG offers an advanced sealing system for loose stones in which are sealed in a secure and tamper-proof casing.
The AIG Certi-Card Sealing System is the best way to safeguard your stone against being substituted,
chipped, fractured, or otherwise damaged before you have it set into jewelry or while it is not in your possession.
The seal has a number of security features including electrostatic security bars, pressure-sensitive
transparent adhesive and Crypto print text which only becomes visible after opening the seal. It is therefore impossible to tamper with the seal.
