High Pressure High Temperature
When processed under severe conditions of pressure (approximately 70000 atmospheres!) and temperature (approximately 2000°c) some natural brown diamonds (Type IIa) can permanently change their color to that of luxurious looking extraordinary colorless gemstones. This color transformation is irreversible and is lifetime guaranteed.

High grade purity and color diamonds are very rare, and command high prices, especially in bigger sizes. Our naturally treated gems provide you with an affordable alternative.

Often starting with the rough diamond, successfully achieving a high quality product requires skillful attention during the sorting, manufacturing and treatment preparation phases. With several years of experience in manufacturing and marketing these exceptionally beautiful natural diamonds, we will be glad to supply you with any diamond that you may specify
All of our HPHT processed diamonds are certified from sizes of 1.00 ct and upward, and each is supplied with all the required notification, and with full disclosure of the color of origin.
