Our Diamonds

Every diamond is GIA (Gemological Institute of America) certified, guaranteeing their excellence according to the 4 "C"s (Carat, Color, Clarity, Cut). Second, every diamond needs to meet the rigorous high standards of Onassis Jewelry Collection experts, who evaluate each and every diamond selected - from central stones to pavĂ© settings.


Allowing the diamond's natural brilliance to shine through is vital in every one of our designs. From the center diamond for a solitaire piece to diamond-paved rings and creative wedding bands, the key is finding the right balance between stunning, unique designs and delicate settings.
