Yves Lemay | Aug 09, 20

Pearls are unique among gemstones, being the only ones found within a living creature and the only ones that require no fashioning before use. Another distinctive feature is its near-exclusive use by one gender. Although some efforts have been made to market pearl jewelry to males in recent years, pearls remain the most "feminine" of all gemstones. Designated officially as the June Birthstone, it is, unofficially, a near requirement for brides.

How gemstones get their colors

Color in minerals is caused by the absorption or lack of absorption of various wavelengths of light. When pure white light, containing all wavelengths of visible light, enters a crystal, some of the wavelengths might be absorbed while other wavelengths may be emitted. If this happens, then the light that leaves the crystal will no longer be white but will have some color.

Mohs scale of hardness

Hardness is one measure of the strength of the mineral's structure relative to the strength of its chemical bonds. It is not the same as brittleness, which is another measure of strength, purely related to the structure of the mineral. Minerals with small atoms, packed tightly together with strong covalent bonds throughout tend to be the hardest minerals.
