While getting that personalized diamond ring from the store you must have heard about HPHT diamonds. Designed during the 1950s to make the diamond industry more rewarding, the process of making high-pressure, high-temperature (HPHT) diamonds is contrarily affecting the present industry. HPHT diamonds are more affordable than their natural partners and build up a fundamentally better color after going through this process.

Jewelry stores in california buy cheaper, less desirable diamonds, put them through the HPHT process, and sell the subsequent (and better looking) diamonds at a lot higher cost. The HPHT process permits producers to choose imperfect or discolored diamonds and modify them into more desirable colorless, pink, blue, or canary yellow diamonds.

Process:

HPHT diamonds are exposed to incredibly high temperature and pressure inside uncommon machines in a lab to reproduce the process that happens somewhere inside the Earth’s crust. Temperatures take off as high as 2,600 degrees Celsius to impersonate the naturally occurring heat in the earth essential to make a natural diamond. The exorbitant expense of the energy and apparatus needed to perform such an errand brings about a desirable (and worthwhile) item — a colorless diamond.

Concerns:

Jewelry stores in California say with numerous consumers needing to buy the “greatest and best” diamond, the demand for HPHT diamonds developed. These upgraded stones permit consumers to get a bigger stone with preferred color for less than what they would pay for a natural diamond of similar specifications — yet at what cost? Buying HPHT diamonds isn’t suggested for a few reasons. These improved stones can show traces of color noticeable from the side of the stone upon close inspection. They also will, in general, lose a portion of their original weight and clarity during the process. Much more concerning is that HPHT diamonds will, in general, be attractive, and some can even be gotten by attractive force!

HPHT must be utilized on high-clarity diamonds (VVS1, VVS2, VS1, VS2, and flawless) because the limit pressure and temperature can make diamonds with inclusions or breaks detonate during the process.

Reactions From the GIA:

It’s hard to recognize natural diamonds from HPHT jems, so a few consumers incidentally buy improved diamonds thinking they are real. The Gemological Institute of America (GIA) needed to cure the present circumstance to assist forthcoming purchasers with knowing whether they were taking a gander at a natural or upgraded stone. A group, driven by the GIA’s director of examination, Dr. Wuyi Wang, put diamonds through a torrent of tests to show if they were natural. They found that to separate the HPHT from the natural diamonds, progressed spectroscopic methods should have been utilized. An instrument called the DiamondView is used to identify manufactured diamonds by searching for unique spectroscopic obvious highlights like an absence of natural graining in the stone.

Final words

Jewelry stores in California are exploring different avenues regarding HPHT treatments, and not all are denoting these improved stones with legitimate ID. Therefore, it is getting more and more hard for industry professionals and GIA analysts to separate among natural and HPHT diamonds. Specialists at the GIA keep on growing new procedures to recognize HPHT jewels; however, staying aware of the creating innovation is testing.
