- Definition of gemstones

Gemstones are naturally occurring minerals prized for their beauty and rarity. They are assessed based on various criteria: composition, which determines their unique chemical makeup; hardness, measured on the Mohs scale to assess their resistance to scratching and abrasion; cleavage, which refers to how a gemstone breaks along particular planes; color enhancement, which may involve treating or altering a gemstone's color to improve its appearance; specific gravity, which compares the weight of a gemstone to an equal volume of water; pleochroism, the ability of a gemstone to show different colors when viewed from different angles; dispersion, the ability to split white light into its component colors; and refractive indices, which determine how light is bent as it passes through a gemstone.

Popular blue gemstones include sapphires, which are composed of corundum and are incredibly hard (9 on the Mohs scale) and have a high refractive index, making them prized for their brilliance. Aquamarine, a type of beryl, is also a popular blue gemstone known for its vitreous luster and hardness (7.5 to 8 on the Mohs scale). These gemstones are valued for their striking blue color and exceptional physical properties.
