Color A gemstone’s color depends on its mineral composition and response to light; unique qualities like asterism, chatoyancy (cat’s-eye effect), or iridescence may also contribute.
Precious gemstones (also referred to as jewels, fine gems, or natural stones) are minerals that have been cut and polished for use as jewelry. Rocks, organic materials (such as amber, jet, and pearl), non-mineral substances, and synthetic substances that exhibit aesthetic qualities also qualify as gems when they exhibit beauty and value. Gems are valued for their color, luster, durability, and other physical characteristics like refractive index dispersion cleavage fracture pleochroism; additionally, their rarity and notoriety make them valuable commodities.
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. Precious stones may be natural or enhanced, the latter being treated using heat or chemical enhancement methods that alter their clarity or color to increase value further.
Most crystalline minerals found on Earth, such as diamonds, sapphires, rubies, and emeralds, can be considered precious. All four belong to the corundum family of minerals, sharing similar chemical composition yet differing in atomic structure and hue due to trace impurities like beryl (which makes up an emerald), which acquires its green hue from trace amounts of chromium; otherwise, it would remain colorless (known as aquamarine). 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.
Other stones, such as smoky topaz and tiger’s eye, are known for their ability to change colors in response to light, known as aventurescence. Gems with this property are known as cabochons.
As well as color, a gemstone’s beauty is determined by its luster and transparency. The higher its luster is, the more expensive its stone will be; At the same time, transparency measures whether a gem is transparent or opaque – with high levels of transparency being valued by collectors.
