HPHT Diamonds

HPHT diamonds also known as High Pressure High Temperature diamonds are much like natural diamonds. The only major difference distinguishing the two is that they are grown above the earth’s crust in laboratories. The same environment is provided inside the laboratories which is equivalent to the environment which the natural diamonds get deep inside the earth’s crust.

The quality, shine and hardness in case of both type of diamonds is the same. So it is always better to purchase the HPHT diamonds. They are also called as synthetic diamonds, man-made diamonds and lab made diamonds. Diamonds are a women’s best friends so when they are available at a cheaper price when compared to natural diamonds one should go for HPHT diamonds.

Process of HPHT Diamond

Carbon is placed inside a graphite capsule. A seed is inserted on which the diamond crystal would grow. A temperature of above 1500 degree Celsius is provided. It is not a process of few days. It takes many days to complete the process. What you get is a diamond which can later be cut and further polished to churn up a gem.

HPHT diamonds are grown in a small capsule which is placed in an apparatus capable of generating pressure and temperature which are very high and similar to those that are there deep inside the earth’s crust. Inside the capsule what happens is that the diamond powder material starts dissolving in molten metal flux and it further crystallizes on the seed to form the synthetic diamond crystal. The process of crystallization period sometimes takes days or even months to create crystals.

Are HPHT diamonds cheap??

Yes of course. HPHT diamonds are much cheaper when compared to their natural counterparts. The natural diamonds are transformed through geological process not in a few days. They take hundreds of years to transform into what they are. On the other hand the HPHT diamonds are made in days. Well considering that the quality of both diamonds is the same as far as shine, hardness and longevity is concerned. The HPHT diamonds sell at a much cheaper price when compared to the natural diamonds.

What is the resale value of HPHT diamonds vis-à-vis natural diamonds

There is not much difference between the resale value of a HPHT diamond when compared to the natural diamonds. Both carry discounted values when resold. Moreover the price variation in case of discounted value is not much in both the cases. Considering that both HPHT diamonds and natural diamonds look exactly the same and also considering that the resale value of similar types of both diamonds is also the same it is always better that we buy HPHT diamonds. This is due to the fact that HPHT diamonds sell at much less price as far as their initial value is concerned.

The quality of both diamonds is not distinguishable by a naked eye. Tests need to be conducted in laboratories to distinguish between both of them. These tests involve equipments which are very costly. It is very difficult for a jeweller to tell the difference between HPHT diamonds and natural diamonds.
