Involved in colour enhancement of CVD and natural diamonds using the HPHT technology, Solitaire Processing Technology is on its way to becoming a majors force in this sector.
The diamond industry is on a roll – demand is high, not only in India, but in the US and China as well. This is good news, not only for diamond manufacturers, retailers and exporters, but also for those associated with the diamond trade, directly and indirectly. Accordingly, companies such as Solitaire Processing Technologies LLP are also looking at a bright future ahead.
The HPHT method exposes stones to extremely high temperatures and high pressures. In fact, the conditions are similar to those in which the stones were formed millions of years ago. The treatment is irreversible, as it essentially upgrades the diamond’s colour. Depending on the original stone, the change in colour can be slight, or quite dramatic.
As Lab-Grown Diamonds are becoming more and more popular, Solitaire Processing Tech has
undertaken colour enhancement of this category of diamonds as well. “The HPHT process is done on
CVD (Chemical Vapour Deposition) diamonds & Natural diamonds as well, which enhances the
colour of the diamond by at least one, and often more than one colour grade, but the purity remains
the same.
