Posts Tagged ‘Man Made Diamonds’

While most people still think of diamonds as being created over millions of years deep in the earth’s crust, increasing concern over the environmental degradation that often results from diamond mining is causing more and more people to reconsider the purchase of mined gems. Many are choosing more reasonably priced man made diamonds instead.

It is a pleasure to regard the sparkle, fire and brilliance of a well cut diamond. For many years, this stone has symbolized love and commitment between partners. It is unfortunate that the diamond mining process does not reflect this beauty — in fact, it is quite the opposite. As much as a ton or rock and earth must be removed to get a single one-carat gem. A tragic, ugly scar on a once beautiful landscape is the sad reality of diamond mining.

But that is only the beginning. This method of mining damages the local ecosystem greatly and pollutes the surrounding streams and rivers with huge amounts of cyanide and mercury (the products used to free gems from their rock casings). This adversely affects humans and animals alike. Luckily, recent developments in man made diamonds provide an excellent, environmentally responsible option.  Read more...

Fake diamonds seem to possess a negative connotation nowadays. Perhaps it will take quite some time before fake diamonds will have a good image. A lot of people are asking, what are these so-called fake diamonds? Let’s face it, diamonds are everywhere. There are lots of colors, kinds, sizes, and shapes of diamonds. These fake diamonds that we’re referring to aren’t diamonds that are downright shams and not dull. These fake diamonds are also called simulant diamonds. Simulant diamonds are not the same as synthetic diamonds. Nonetheless, simulant diamonds are also lab-grown diamonds. These diamonds undergo certain scientific processes that imitate the natural process of creating diamonds.

The two main ways in which simulant diamonds are created are through chemical vapor deposition, also known as CVD and high pressure and high temperature, which has the acronym HPHT. High pressure and high temperature is a more basic and more crude method of crafting these simulant diamonds. In essence, just like how diamonds were created more than 3 billion years ago, a piece of carbon is exposed to tremendous heat and pressure in order to come up with a sparkling diamond.  Read more...

How can one purchase the fire and scintillation desired in a diamond at a reasonable price? This is the question diamond lovers everywhere who are deterred by high gemstone prices are asking. The once popular, inexpensive synthetic substitute, cubic zirconia (CZ), is heavier and far less fiery than real diamond, and larger CZs can’t even pass for real to the naked eye. However, all is not lost. Lab- created diamonds are finally here, and they aren’t pale imitations of the real thing any longer. These flawless gems ARE the real thing — chemically and visually identical to natural stones.

Cultured, or man-made, stones are the same carbon crystals with the same chemical, optical and physical properties as those stones that nature created in the underground mines throughout the world. Cultured stones offer the same brilliance, sparkle, fire and scintillation. The Gemological Institute of America (GIA) grades the cultured gems by the same standards it uses for the mined ones, although its rating describes the stones as “laboratory grown.” In fact, the GIA acknowledges that these ARE diamonds, just man-made.  Read more...

An understanding of the differences between a lab produced gemstone and a naturally mined one is quite useful when considering the purchase of diamond jewelry.

Old methods of synthetically creating diamonds produced stones that were far inferior to natural gems. Cubic zirconia, as they are often called, were looked down upon by the jewelry industry. However, modern technology now allows scientists to produce gem-quality cultured diamonds in laboratories all over the world. Lab created stones take a matter of days to grow, rather than the millions of years that are required by nature. The Gemological Institute of America (GIA), the leading research and grading body in gemology, recognizes some of these lab produced stones as real diamonds.

There are two basic ways that man-made gems are created. HPHT (high pressure high temperature) is a process that has been used for several decades. While this method does simulate the natural way that mother earth makes these precious stones, and physically, visually, and chemically they are almost exactly the same as those found in the earth, these synthetic stones can be identified by a trained gemologist using standard gem-testing equipment.  Read more...

It’s not surprising at all to see backlashes and adverse reactions about lab diamonds. Lab diamonds have been proven by science to be just as real as authentic diamonds in terms of makeup. In fact, it’s even better. Hybrid diamonds can be made by two procedures: chemical vaporization deposition or CVD and the HPHT or high pressure and high temperature method. The HPHT is clearly favored because it is much cheaper than CVD. CVD is a process that’s more scientifically evaluated because it requires all the elements of HPHT along with some added components like carbon gas.

Carbon gas is utilized in order to trigger crystallization on a diamond seed within a superheated vacuum chamber. This, along with the components of HPHT makes for a more refined diamond that precisely looks like an authentic diamond. In addition to that, because new technologies and scientists are now able to bring the price of producing diamonds down, a lot of applications have also emerged. These are applications that are considered to be essential in our industry today. Suffice to say that lab diamonds have definitely entered a new age.  Read more...

Diamond engagement rings are a image of love and unity. Diamond engagement rings are a strong symbol of romance and are the precedent to a wedding. The engagement ring contains a terribly vital role of symbolizing the unity of 2 people in everlasting love. A chunk of Sona Diamond Jewelry which has such an necessary meaning should be created with the simplest materials in a very lovely style which can be proudly worn and kept forever.

As a result of diamonds found in nature take such a while to develop and they’re terribly expensive too. Simply as a result of diamonds are expensive will not mean anyone should fail to see having a lovely diamond engagement ring. There’s now an alternative method to making diamonds by Sona Diamond that makes owning a diamond a more cost-effective reality.

Diamond rings don’t seem to be only for the wealthy. Sona Diamond’s New technology have enabled scientists to grow diamonds from a little ion crystal in an exceedingly lab environment. These diamonds solely take days to grow instead of the scores of years that it takes for nature to supply diamonds that may be mined.  Read more...
