What is a colorless diamond?

Cut, clarity, carat weight, and color are the qualities that define the unique beauty of your diamond. The Gemological institute of America has created a scale to measure diamond color, ranging from D (colorless) to Z (yellow). While D is considered top of the scale, diamonds graded D, E, or F, are all considered colorless, as any trace of color cannot be detected by the untrained eye. Among the rarest, most exquisite diamonds, colorless diamonds are a stunning declaration of your love.
