What does ruby look like in the ground?

It is much easier to tell if a ruby is real when it is raw and uncut, for a variety of reasons. Rubies like to grow in a flat, hexagonal shape. If the uncut gem shows this natural growth characteristic, along with parts of its host rock (marble or alkali basalt) still attached, it is very likely it is a real ruby.

How do you identify a natural ruby?

The rub test includes rubbing your ruby across a smooth (but hard) surface, like glass, and seeing if the gem leaves any color behind. Glass only has a hardness of 5 on the Mohs scale, so it's much softer than actual rubies. Real rubies and some gems shouldn't leave any color behind, but cheap fakes or imitations can.

How do you tell if my rock is a ruby?

Real rubies glow with a deep, vivid, almost "stoplight" red. Fake gems are often dull: they are "light, but not bright." If the gem is more of a dark red, then it may be garnet instead of a ruby. If it is a real ruby, however, know that darker stones are usually worth more than lighter stones.

How do you remove rubies from rocks?

A high-pressure stream of water washes the gravel away from the stream deposits. As the rocks containing the rubies are dense therefore they remain in place while the smaller deposits wash away. The gemstone is extracted by hand from these deposits as they are small and irregularly shaped.
