Onyx is a sedimentary rock, formed as stalactites and stalagmites in cave interiors. … While vulnerable to chemical and abrasive attack, the decorative appeal of onyx is perhaps unsurpassed by any other material.
Is Topaz anisotropic?
Topaz is anisotropic and shows a moderate dichroism of two tones of the body colour. … Rough topaz crystals usually present as elongated orthorhombic prisms.
Can a diamond shatter inside?
Diamonds do not crack. Diamonds will not crack a little. You will either chip the diamond completely or not all. Often a client will see an inclusion in a diamond and think it is a crack -rest assured these are just inclusions. Inclusions in diamonds don’t usually lead to a diamond chipping.

Are Diamonds anisotropic?
Diamond is crystalline and anisotropic, meaning that its properties are directional. The single crystalline diamond shown in the left picture contains lots of facets. In contrast, amorphous diamond is isotropic like glass, and it may be cut to any shape including an ideal sphere.
Is Emerald anisotropic?
Emerald is anisotropic and displays moderate dichroism of bluish green and yellowish green. Gemmologists can use many different instruments to identify emerald. … Rough emerald crystals are usually long, hexagonal prisms.
Is graphite isotropic or anisotropic?
The distance between adjacent layers is appreciable. Carbon atoms are arranged in different layers and each atom is covalently bonded to three of its neighboring atom in the same layer. Hence the transfer of electrons is possible. Hence graphite is anisotropic with respect to the conduction of electric current.
What’s harder than diamond?
