At the request of the owners, we study all types of diamonds: round diamonds, princess diamonds, emeralds, pear diamonds, oval and radiant diamonds, dry diamonds, cushion-cut diamonds, heart-cut diamonds and marquise diamonds.
Often investment diamonds from the 80's with or without gemology certificate.
We estimate all diamonds for free but when buying we generally prefer diamonds above 0.5 carat.
Also we have preferences in terms of gemmology certificates, so we will prefer a GIA or IGI certificate rather than an AIG certificate for example.
We are also a buyer of very old diamonds (CIBJO or SCAN).
In this regard, we are regularly approached by individuals who have unfortunately been victims of diamond investment' telephone scams.
Unfortunately, these diamonds often have no financial value and we call on individuals to be extremely vigilant against this type of scam.
