HP-HT Colors Enhancement Process
A natural diamond can be termed as the best “wonder of the world“ with its various color effects.
The diamond rises from beneath the earth, we make it more beautiful by simply enhancing the richness in color.
The color of the natural diamond is enhanced by sophisticated advanced technology called hpht (high pressure heat treatment).
We replicate the same method by which earth produces the natural fancy color diamond.
We simply enhance the natural colors to beautiful colors without using any harmful methods.

Our diamonds forever reveal its beautiful rare colors.

HP-HT Color Enhancement Process
Natural Fancy Colored Diamonds are extremely rare and are highly priced because of their rarity.

Fancy Diamonds are completely out of reach of ordinary people and also for the Diamond dealers unless you can pay  $30,000 for a 1 carat vivid yellow, $150,000 for a one carat fancy blue, and $500,000 and more for a one carat fancy intense red.

HDPL Color Treated Diamonds TM attains what nature can only produce in scarce quantity. We color treat dirty industrial diamonds and transform them to magnificent fancy colored ones and that too at unbelievably low prices. 

WE COLOR ENHANCE from brown diamonds OF type IIa , and turn them into white colors usually from D to H and also to Fancy Pink.

There is also a part of those brown diamonds that can be made Fancy Blue.

Brown diamonds from the type Ia goods are color treated to make Fancy Green , Fancy Intense Yellow , Fancy Vivid Yellow , Fancy
Greenish Yellow , Fancy Orange colors.
We also Color Enhance from  WHITE TO "CANARY YELLOW" Diamonds.

Below is a chart which shows the current world wide Price ratings of Fancy Colored Diamonds:

The following table lists the different colors diamonds can take.The diamonds are listed in order of decreasing price. Red diamonds are the rarest and thus fetch the highest prices:

Price Color grade
1 (highest) Red diamonds
2 Orange-yellow diamonds
3 Pink diamonds
4 Green diamonds
5 Blue diamonds
6 Yellow (canary) diamonds
7 Orange diamonds
8 Colorless (white) diamonds
9 Purple diamonds
10 Brown (cognac) diamonds
11 (lowest) Black diamonds




Diamonds originate deep in the earth where conditions of intense pressure and temperature exist. They are brought to the surface through geological events which alter the structure and color of the stone.

Diamonds are brought to the surface by geologic forces such as magma flows and volcanic activity. The journey to the surface can change the color of the diamond.

1.Diamonds are formed deep in the earth under the geodynamic conditions of intense pressure and temperature.
 

2.Diamonds are brought to the surface by geologic forces such as magma flows and volcanic activity. The journey to the surface can change the color of the diamond.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


3.To geodynamically restore the color in a diamond, a rough stone is placed into a press that replicates the conditions deep in the earth. As the pressure and temperature increase the color is restored resulting in a HDPL Color Treated Diamond TM
 

4.Once the color in the diamond has been geodynamically restored, the rough stone is cut and polished.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
     
Thus the SAME NATURAL CONDITIONS when created in the laboratory produces Magnificent "FANCY COLORED DIAMONDS" in the shades of Green, Canary and the like.

At Heaven Diamonds we recreate such natural conditions and produce these wonderful Fancy Colored Diamonds through High Pressure High Heat (HPHT) process.

We also provide "FULL CONSULTANCY" for Color Treatment of Diamonds, including Machineries, Technology, Processes, Setup and Know How . Our charge for Consultancy and Transfer of Technology is US$ 1.2 million.



PREVIOUS ARCHIVE NEWS:
1) LKI Announces New GE Diamond "Processing" for Loose Diamonds
General Electric will be processing natural diamonds to create a "super-duper diamond" according to Gus Weil, speaking for Pegasus Overseas Ltd. (POL), a newly developed subsidiary of Lazare Kaplan International, Inc. (LKI). LKI has signed an agreement with POL to market gems that will have been processed to enhance certain aspects of the natural diamonds. "This will affect color and brilliance, but not the general clarity," said Weil in an exclusive interview with the Diamond Registry Bulletin.

The process is owned by GE and its specifics are being kept extremely quiet. Indeed, when the DRB asked whether the process was one of physical, chemical, laser or some other type of change, Weil would only state that it did not include laser drilling, irradiation surface coating or fracture-filling. "Although we’re not saying what it is, it is only an additional step in the already lengthy process," said Weil. Using the process of elimination, we assume that the process is either pressure or heat, General Electric’s specialty for years.

Apparently, once the process has taken place – and it is irreversible – a jeweler will not be able to tell the difference between a stone that has been treated and one that has not. Exactly how much difference will be made Will the laboratories mark the certificates with some sort of statement, "processed diamond", for instance? Will the color change be as much as, say, I to G Should one know or be able to tell somehow if one’s diamond has been chemically, physically or otherwise treated? Will other cutters be able to use the treatment or will it remain a proprietary process.

The most interesting question raised by the discussion with Weil is that of "brilliance." If the brilliance of the diamond is affected, how is that possible without changing either the material involved, i.e. the carbon, or changing the faceting of the stone? Indeed, by keeping its process so under wraps, GE seems to raise more questions than it answers.

POL will be marketing the processed stones only, which, at this time, will be sold with the standard certification for diamonds.


2)  Altering Diamond Color by Irradiation Process in Nuclear Reactor
In order to alter their original color, diamonds can be irradiated using a nuclear reactor and controlled heating known as "annealing". This improves the color of the diamond, to make it appear the same shade as natural fancy colored diamonds such as yellow, blue, green, brown, and pink diamonds. Sophisticated equipment, such as an infrared spectrometer, is needed to identify the origin of color.
Today diamonds are color treated in an electron accelerator where they are exposed to a stream of electrons turning the diamonds to a greenish hue. Then through a heating process the stones are annealed to the yellow, orange and brown colors. The diamonds do not become radioactive in this treatment and therefore can be used in jewelry immediately after the color change process.
Basically, the radiation bombards the atoms in the gemstones, knocking them either out of the stone, or moving them around inside the stone. The removal from the stone, or relocation inside the stone, causes the stone to react to light differently, which causes the stone to offer a different color.Does this treatment save money Oh Yeah! Without the radiation of gemstones there would be very few colored diamonds on the market.
