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 magnificient 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:

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. |

2Diamonds 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. Some stones retain color and are known as "fancy-color" diamonds.

3To 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

4Once 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
Magnificient "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.

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) Another Big Company Is Selling HPHT Treated Stones
Another big company is entering the high pressure high temperature field, competing with General Electric.
The company is called U.S. Synthetics. They say that they are the biggest manufacturer of synthetic diamond components for use in oil and gas drilling. Its new division, HDPL, can permanently change brown and cape diamonds to fancy colors, including yellow, orange and green, and take Type II diamonds from unmarketable colors to colorless or near-colorless.
Rob Galloway, general manager said in an interview with the Diamond Registry Bulletin that they have been working on this process for two years and the new process is very similar (but not exactly the same) as GE’s.
From what we hear, there may be other, smaller companies also treating stones.
The company requires all its customers to sign an agreement disclosing the treatment in all sales. It is also assisting industry laboratories and institutions with HPHT detection and research.
3) 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.
