Ruby's chemical make up is AL2O3:CR, that means that every molecule in it has 2 atoms of aluminum, 3 atoms of oxygen connected to an atom of chromium. In the 1800's chemists figured out that by combining aluminum oxide with chromium at high heat they would get synthetic ruby.

The process has been modified through the years but, chemically speaking, synthetic ruby is the same as natural ruby. From a retail point of view they are worlds apart and man-made stones must be marked as such and cannot be sold as ruby.

How do you know if it is real garnet?

In general, gemologists identify gemstones by physical characteristics such as chemical composition, refractive index, specific gravity and hardness. In the case of ruby, a gemologist also has to distinguish between natural ruby -- ruby occurring in nature -- and synthetic ruby -- ruby produced in a laboratory through a process such as flame fusion. One of the signature characteristics of a synthetic ruby is curved growth lines formed as the crystal grows upwards in an environment with a high thermal gradient.

Is there another mineral that can be used if ruby runs out?

Scientists may find out another mineral. It is also possible to make synthetic rubies.

How do you identify a real ruby gemstone from synthetic using 10X glass?

Ruby, the gemstone, is the red variety of the mineral corundum. Corundum is crystalline aluminum oxide (alumina). Ruby's red color comes from a small amount (a percent or so) of chromium impurity that substitutes for aluminum in the crystal structure. Other impurities give corundum other colors: gem sapphire occurs in a blue variety where the impurities are iron and titanium Naturally occurring ruby crystals formed slowly at high temperature deep in the earth. A rock containing ruby is unmistakably "natural" as the rock texture is not reproducible in the lab. Also diagnostic are small mineral inclusions in natural ruby. "Fake" ruby results from mis-identification of another red mineral, commonly garnet or tourmaline, or of colored silica glass. These mis-identifications are relatively easy to detect making use of physical properties. For instance, ruby is much harder than tourmaline, garnet, or especially glass. As well, fake rubies are often less dense than the real thing. It's easy to do these physical tests. Now comes the hard part: telling natural from synthetic ruby As is the case for diamond, a lot of ruby crystals have been grown (synthesized) in the lab. Growing rubies is by no means easy, but unlike mis-identified ruby, synthetic ruby is no less "real" than natural ruby. It can be extraordinarily difficult to tell the two apart. In the Verneuil synthesis process (used for over a century), rubies are grown by dripping fused alumina onto a plate, where it crystallizes. Characteristically curved growth features--observed with a microscope-- remain in the synthetic single crystal and are tell-tale signs of a synthetic origin. Heat treatment changes the internal features of the crystal making detection of this type of synthetic ruby more difficult. More recently, the appearance and physical properties of ruby crystals grown in a flux can be made to be essentially identical to those of natural ruby. Chemical analysis to detect trace amounts of impurities characteristic of the flux--like lead-- may be the only way to tell natural from synthetic. Usually Real rubies are heavier than the fake one!

What is ruby bridges best qualitys?

Rubies are hard...on the hardness scale they are next to diamonds with a hardness of 9.0...A ruby laser is a solid state laser that uses a synthetic ruby crystal as its medium. Ruby lasers produce pulses of visible light and deep red color....They are used in a number of applications where you need short pulses of red light...for making holographs...and tattoo removal

What is the jewel ruby used for?

The most common use for rubies is jewelry—stunning jewelry! However, both natural and synthetic rubies are used in a variety of applications—such as watchmaking, medical instruments, and lasers—because of their incredible strength and red fluorescence.

What are clock jewels?

Clock jewels are the bearings used in expensive spring-wound clocks and watches, so called because they use a natural or synthetic jewel surface such as ruby or sapphire.
