Full Color Spectrum

Every Color We Grow

From the purest colorless Type IIa to saturated fancy vivid hues — our laboratory produces the complete diamond color spectrum. Colorless uses CVD with post-growth HPHT treatment. Fancy colors are grown by introducing trace elements during the growth process, then enhanced via post-growth treatment.
