With the purchase of each diamond jewelry piece from ALO diamonds we issue a certificate of authenticity,
verified by the Czech Gemological Laboratory.
This document is equally important for a diamond as is a birth certificate for a person or the property record for a home. The certificate describes the unique characteristics of each individual gemstone, as well as its size, and color. Also, the certificate verifies that the diamond was purchased legally.
With a purchase of diamonds larger than one carat you will also receive a certificate of authenticity from the GIA International Gemological Laboratory – one of the most widely recognized gemological institutes in the World, HRD (Hoge Raad voor Diamant – The Diamond High Council), EGL (European Gemological Laboratory) or IGI (International Gemological Institute).
