The Irradiation & HPHT processes are suited to manufacture most of the colors except True Pink. The reason is that these processes yield very few pink colors and even then most of them have purplish undertones. Hence, we started using a new coating process to manufacture Ice Pink Diamonds. This not only yields a natural looking Pink color but also the process allows us to manufacture as many as we need.

The coating materials used in the past were very unsophisticated and outdated compared to the irradiation and HPHT techniques used now. But technological advances have allowed us to use more sophisticated and durable coatings. The coating process results in a very thin film at the pavilion of the diamond which imparts the color to the rest of the diamond. Hence, once the diamond is set the color cannot be easily damaged as there is no coating on the table. Designs where the pavilion of the diamonds is covered should be chosen.

The beauty of this treatment is that the process can be undone and redone quite easily.

Colors Manufactured by Lotus Colors using Coating - Ice Pink

Ice Pink diamonds (coated), like all diamonds, are hardy and durable, resistant to general wear and tear, unless they’re subjected to extreme temperatures (above 500 C) or the pavilion is exposed to acids or abrasive materials (recutting or exposure to the jewelry polishing wheel). Also, the beauty of this treatment is that if the coating is damaged the process can be undone and redone quite easily.
