IGL offers an advanced sealing system for loose diamonds in which a diamond is sealed in a secure and tamper-proof casing. The IGL Certi-Card Sealing System is the best way to safeguard your diamond against being substituted, chipped, fractured, or otherwise damaged before you have it set into jewellery or while it is not in your possession. Once IGL has issued a Diamond Certificate, on your request the diamond is sealed in the Certi-Card casing with its individual IGL Diamond Certificate number and identifying characteristics clearly visible inside the seal. The seal has a number of security features including electrostatic security bars, pressure-sensitive transparent adhesive and Cryptoprint text which only becomes visible after opening the seal. It is therefore impossible to tamper with the seal.
