Precious gemstones (also referred to as jewels, fine gems, or natural stones) are minerals that have been cut and polished for use as jewelry.

Precious gems come from all areas of Earth’s crust, mantle, and core. They may be found within igneous, metamorphic, sedimentary rocks and minerals and mined underground before being sold to lapidaries for cutting and polishing.

Furthermore, rubies may either appear red or purple depending on iron content.

Many gemstones, like tourmaline and opal, are known to showcase multiple hues. While sliced and faceted slices may best display these multicolored gems, sometimes leaving the stone raw can highlight its unique striped patterns or natural inclusions created during formation.
