Diamond Coloring Services

Natural diamonds can be treated to produce a variety of fancy colors including hues of blue, green, yellow, pink, etc. by our process. This process is permanent, irreversible and does not alter any other property of the diamond except the color.

Colors

The photo above shows some of the colored diamonds produced in our lab. In general, we can process any diamond to hues of blue, yellow, green, orange, red and pink. For best results, we recommend brownish stones to be processed blue, green or orange and cape stones to be processed yellow or green. White stones can be processed for any of the colors. To obtain best results, remember a simple thumb rule: Better the starting stone, better the resulting processed color.
