What other security measures does the DCLA offer ?

You can have your certified diamond sealed in a DCLA Certicard ® Seal which will provide a further safeguard against your stone being substituted. The seal has a number of security features including electrostatic security bars, pressure-sensitive transparent adhesive and Cryptoprint® text which becomes visible after opening the seal. It is therefore very difficult to tamper with the seal. This sealing will also protect your diamond against damage and dirt.
