A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
The garnet group comprises a series of related silicate minerals, including almandine, pyrope, spessartine, grossular, andradite and uvarovite, among others. These species form an isomorphous series with diverse compositions and colors, ranging from deep red and orange to green, yellow and colorless. Garnets generally have Mohs hardness 6.5–7.5 and no cleavage, offering good durability and strong refractive indices that give them lively brilliance when well cut.
