Man-Made Diamonds

Man Made Diamonds.Diamonds-2

There has been a great deal of discussion about lab-created diamonds.  The jewelry lover, who is interested in realizing the huge savings and aesthetic beauty that simulated diamonds offer, is often bewildered by the manufactured diamond industry jargon and available options.

‘Man made diamond’ is also known as synthetic diamond and this ‘man made diamond’ or the ‘lab created diamond’ undergoes a chemical and physical process in the diamond mines.  The main difference between ‘Man made diamond’ and the natural diamond is the composition of three dimensional carbon crystals. 

The ‘lab created diamond’ or the ‘man made diamond’ is known by various names such as manufactured diamond, artificial diamond, industrial diamond or the cultured diamond.  ‘Man made diamond’ is manufactured either from the silicon carbide or the cubic zirconium.

History of the Lab Created Diamond.

The first ‘man made diamond’ was manufactured in Sweden in 1953 by Quintus and by an engineer Anders Kampe.  This lab created the diamond manufacturing process in which bulky and huge machines designed by Baltzar Von Platen were used.  After one year General Electric took a giant step in manufacturing the ‘man made diamond’ and the industry came into existence in the nineteenth century. 

The main industrialists in lab created diamonds or the ‘man made diamonds’ were the GE Super abrasives and the De Beers Industrial Diamonds.

Around 1980 industries were formed in Korea.  The Chinese later became pioneers in the lab created diamond process.  The GE Super abrasives ‘lab created diamond’ unit was sold to Little John and this was named the Diamond Innovation Company of 2003. 

During this same time De Beers Industry was divided into two different ‘man made diamond’ industries and the second industry was known as Element Six.

Today the ‘lab created diamond’ has a market of one billion dollars and produces around three billion carats of the man made diamonds in a year.  Out of these three billion carats only 130 million carats are used in the manufacturing gems.

Manufacturing Process.

To create a diamond, there are basically two methods that are used now.

One of the methods is a high pressure, high temperature method and commonly known as HPHT method in the ‘man made diamond’ manufacturing arena. 

The production cost is less in this process, making it a more popular method which is used world-wide.The main accessory used is a heavy press that provides a pressure of 5 GPA and the temperature that is formed due to this pressure is around 1500 degree Celsius. 

The diamond better known as a ‘man made diamond’ is created by copying the procedures naturally occurring inside the earth’s crust. In this process there are two types of presses used – a belt press and a cubic press.

Another method used in ‘Lab created diamond’ is the Chemical Vapor Deposition which is also called the CVD method. In this method carbon plasma is formed on the top where the tiny carbon atoms that are made form a ‘Man Made Diamond’.  In this CVD various gases are used to energize the suitable conditions for diamond growth on the top layer.  This method of Chemical Vapor deposition was introduced in 1980.

Quality Variances.

There are three primary grades of simulated diamonds — high, medium, and low.  For the jewelry shopper it should be noted that the quality of setting goes hand-in-hand with the quality of the gemstone. 

The manufactures of diamond costume jewelry use low quality or scrap stones that are not gem quality, and have disco ball appearance or look murky. 

TV shopping channels that sell manufactured diamond jewelry with a sterling silver, or micro-thin layer of gold plated over silver settings, also use medium stones not of gem quality. 

Those that sell solid 14K gold or solid platinum settings, as a rule, use the highest gem-quality man made gemstones that replicate mined diamonds.

Industrial Uses.

  • Diamonds are now being used to machine tools, especially non-ferrous alloys.
  • CVD diamond also has applications in electronics.  Conductive diamond has been demonstrated as a useful electrode under many circumstances.
  • Diamonds are also being used as radiation detection devices.
  • Diamonds have uses as semiconductors because they can be contaminated with impurities.
  • Diamond is the ideal material.  It can be used in computers to run them at speeds that would melt anything on the market today.
  • Diamonds can also replace rubies to make lasers of extreme power.
  • Diamonds can be used as memory storage devices which could be so small as to allow a cellphone to fit into a watch and an iPod to store 20,000 movies.

Pricing. Low grade stones are sold in bulk to costume jewelry makers and are often glued on electroplated settings.  This jewelry is fine for children, where loss risk is high, and usually retails for less than $15 per item.  

Medium grade stones are used primarily in sterling silver jewelry that sells for under $100 per item, settings and stones. 

Medium grade simulated diamonds can be distinguished by the naked eye as not being mined diamonds. 

High grade gemstone quality lab-created diamonds, indistinguishable by the naked eye from mined diamonds, are found mounted on settings of solid 14K gold and platinum.  This is considered to be fine jewelry, with the best quality gemstones selling for under $100 per carat for the gemstones alone.  

Recommendations.

If you buy simulated diamonds set in sterling silver, expect decent stones, but they are not mined diamonds.  With any plated settings, gemstones are low to medium grade, and the plating will eventually chip or wear off, particularly around the edges.  When that happens, the nickel/copper alloys will be exposed.

Simulated diamonds with mined-diamond qualities, must be set in 14K solid gold.  Jewelers who offer lab-created diamonds invest in gold settings for the purpose of creating fine diamond-like jewelry.

Diamond Veneer

The best simulated diamonds & diamond coated cubic zirconia jewelry in the world!

Diamond Veneer Jewelry: THE FUTURE OF CUBIC ZIRCONIA

Introducing the revolutionary process of treating Cubic zirconia with a film of Carbon Diamond particles. This process results in a flawless “G” color on the diamond color scale.

This exciting new concept, known as Diamond Veneer will change the way you regard Cubic Zirconium jewels.

As its namesake states; visually you see a “G” color diamond. The veneer of carbon diamond crystallized around the entire gem creates a perfectly cut Cubic zirconia. This vaporization process under extreme heat and pressure conditions, significantly increases (5-times) the fire, refraction and durability of the CZ as a real diamond at a fraction of the cost.

Diamond Veneer will revolutionize the way you look at CZ’s and will certainly render them obsolete.

Diamond Veneer: Soon to become the iconic term used to define this new, innovative process in this new jewelry niche! As “Kleenex” is for napkins, and “Frigidaire” is for refrigerators.

How do you spell Diamonds at a Cubic zirconia price? Diamond Veneer.
How do you spell luxury at an affordable price? Diamond Veneer.
It’s our dirty little secret!

The best simulated diamonds & diamond coated cubic zirconia jewelry in the world!This revolutionary new Carbon Diamond treatment for the enhancement of gemstones produces very uniform, consistently hard and durable films with excellent adhesion.

Diamond Veneer Technology is generally amorphous, having no overall crystal structure and is the ideal type of coating for gemstones such as Cubic zirconia (CZ).

The film is condensed from a vaporized form of carbon onto the gemstones.

Diamond Veneer uses the Microwave Assisted Chemical Vapor Deposition (MACVD) method of depositing DV film. The resulting process makes hard, transparent well adhering films.
