We use D-colored white diamonds and graduated blue sapphires

Diamonds come in a variety of colors. Since the purest and whitest color diamonds, the D-color diamonds, are the hardest to find in nature and since they are the most sought after, they are the rarest and as such most valuable. D-colored diamonds are considered colorless, meaning that they have no yellow tint.

Excellent color, hardness, robustness and shine

Sapphire is the most precious and valuable blue gemstone. It is a very desirable gemstone due to its excellent color, hardness, robustness and shine. The most well known of the sapphire colors, the beauty of a blue sapphire is unequalled.

Each sapphire's shade is individual and nuanced; no two are alike. With tones going from deep velvety blue to cornflower blue, our blue sapphires are gorgeous specimens of nature's beauty.
