How to Select
The most popular varieties of grossular Garnet are the orange-red Hessonite and green Tsavorite, with the latter generally more expensive. In general, color saturation is an important determinant of value. While the prevalence of imitations often depends on the variety, glass and synthetic fakes are often present on the market. These fakes typically have different hardness but may need professional evaluation to authenticate. In some cases, the Hessonite variety has been passed off under the misleading name "California Ruby."
