Synthetic Sapphires - Gemstones Par Excellence
Sapphire was first synthesized in 1902. Synthetic Ruby - the 'red sapphire', though, was produced in 1888 by the French chemist, Auguste Victor Louis Verneuil, through flame fusion process.
Synthetic Diamonds Are Real Diamonds
It follows from the above that synthetic diamonds are real diamonds. They are made from carbon, exactly the same as natural diamonds.
Synthetic Diamonds are a laboratory-produced imitation of natural diamonds that serve wide range of purposes and are devoid of the properties or constraints of rarity and pricelessness of natural diamonds (provided you think rarity and ...

Synthetics: have the composition of a known mineral, but do not necessarily match the composition of the gemstone it is to mimic.
Synthetic stones are those man made gems which consist of the exact same elements in the exact same crystal form as a natural gem.
Synthetic and simulant are terminology used by the USBM for laboratory grown gemstones. Others in the gemstones industry may use different terms to refer to laboratory grown gemstones.
SYNTHETIC DIAMOND/ GEMSTONE:
A diamond/gemstone created by humans in a lab. Synthetic stones mimic the structure, color, and texture of natural stones making it sometimes difficult to tell a synthetic from a genuine diamond/gemstone.
Synthetic stones were an essential part of this category. These first appeared on the market around 1880. The synthetic ruby was the introductory stone and at the time was considered a great scientific achievement.
Synthetic Red Beryl
Previous Let's Talk Gemstones articles have focused upon properties and data pertaining to natural gemstones. Red beryl is the newest and, probably, the least known gem to be offered.
Synthetic sapphire
A synthetic gemstone resembling a natural sapphire, first produced by the Verneuil Furnace in 1910.
SYNTHETIC STONES
SYN
The tag code may be used to describe "synthetic" materials that have essentially the same optical, physical and chemical properties as a naturally occurring counterpart.
Synthetic Color Diamonds
Synthetic colored diamonds are another affordable option you'll find when you shop for vibrant diamonds. Synthetic diamonds are genuine, but they are created in a laboratory and their origins should always be disclosed.
Synthetic cubic zirconia
Produced by the skull-melt process, synthetic cubic zirconia is an inexpensive diamond simulant and an excellent alternative to diamond.

Synthetic - A gemstone created by humans in a lab. Synthetic stones mimic the structure of natural stones. It's often difficult for gemologists to tell a synthetic from a natural stone (also see created).

Synthetic vs. Simulant Gems
A synthetic has the same chemical and basic physical properties as the natural gem. A simulant gem looks like the natural gemstone. A lab grown diamond is crystalline carbon.
Synthetic stone: Synthetic stones are man made gemstones, usually produced in a laboratory, which imitate the characteristics of naturally occurring gems.
Synthetic Stone Certain hard minerals are found with beautiful colors and are cut into stones to mimic the real gems. They are not glass. They are a higher quality mineral.

SYNTHETIC RUBY
Synthetic rubies were first made by the French chemist Auguste Verneuil, who invented the flame-fusion process for producing inexpensive rubies in 1886. It was a ruby, but it didn't look much like one. In 1918, J.
Synthetic (gemstone) A synthetic gemstone is man-made rather than mined from the earth. Natural gemstones which are treated by industry-accepted methods such as heat or irradiation are not classified as synthetic.
