Diamond Colors

Blue
Titanic as the sky-blue heavens above, infinite peace, calmness, and devotion stretch beyond the end of the world, just like blue diamonds. For most blue diamonds, their color is due to trace amounts of the element boron, which substitutes for some of the carbon atoms in the diamond's crystal lattice.

Yellow
Just as the warm sunlight nurtures life, the flash of golden yellow hue evokes gleams of cheerfulness and curiosity, adding depth to the diamond that catches the eye. Yellow diamonds’ unique color comes from the presence of nitrogen in their composition. Depending on the amount of nitrogen, the color intensity will range from light to dark.

Pink
Pink diamonds are often worn by celebrities as they are the altitude of luxury and are extremely rare. This romantic shade comes from a distortion of the diamond’s crystal structure, though the exact cause of the color remains a mystery. Representing the color of love, happiness, and delight, pink diamonds are a uniquely beautiful choice.
Colored Lab-grown Diamond Specifications
Our fancy-colored diamonds are mostly grown to order.
The process takes 2-4 extra weeks to complete and charges an extra fee of 60%. Colored diamonds (other than black) are guaranteed to be Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark, or Fancy Deep. Clarity and cut grade are not guaranteed due to the nature of customized production.
