Are BNT Diamonds certified and laser inscribed? | BNT Diamonds

Do the BNT Diamonds come with certificates and/or laser inscription?

BNT Diamonds offers only classified & tested diamonds, which are certified by the world most renowned grading institutes. Each polished diamond (above 0.30 Ct) carries its own identity via a unique certificate. This is a laminate-protected document that summarizes a diamond's vital information based on the 4 C’s and describes precisely its characteristics that help determine its value. A certificate does not give any indication of a diamond's monetary value. The most renowned certificates of the diamond industry are:
GIA: Gemological Institute of America
HRD: High Diamond Council – Hoge Raad voor Diamant
IGI: International Gemological Institute

Furthermore all diamonds purchased from BNT Diamonds for investment purposes, starting from 1 Ct, are available upon request with laser inscription of the certification number in the diamond.
