It’s hard to find that perfect flawless diamond without it costing an arm and a leg. Laboratories have come up with a way to make it a bit more financially friendly for the consumer. They have created a treatment called High Pressure-High Temperature treatment (HPHT) which changes the colors of diamonds. This process began in the late 1940s. The process involves exposing the diamonds to a radiation and heat to alter their colors.

Diamonds are classified scientifically into two types with subcategories for each.  Type I diamonds which contain nitrogen are the most found in nature. Type II diamonds are rare and lack almost all nitrogen. Type II are often brown, blue or gray. HPHT processing turns type II brown diamonds into colorless or near-colorless.

 

Treated diamonds are usually less expensive but look just as pretty.

 

Happy Shopping :)
