Originally, every diamond cutter or jeweller himself evaluated his diamonds
to determine their value.
The invention of specialised laboratories in the seventies which use advanced tools allows for a more scientific evaluation of diamonds.
This is how internationally-reknowned labs like G.I.A. (The Gemological Institute of America) and H.R.D. (Hoge Raad voor Diamant) emerged.
The role of these laboratories is to analyse diamonds and establish a certificate for each one of them to indicate their characteristics: the 4 Cs: diamond weight
, diamond colour
, diamond purity
, diamond size
, as well as their dimensions, fluorescence, polish and symmetry.
A GIA or HRD certificate is provided with each diamond ring that you find on the Edenly website. You will find examples of these certificates below :
