Large spessartine or spessartite garnets are rare, sizes in the 15-50 carat ring can be terribly expensive and extremely rare. Gem manufacturers need to cut many hundred kilos of rough spessartite to dream of striking it that big. In recent years cabochon gems have become the trend, the smooth finish on the gem delivers a nice light reflection that is not distracted by facets, angles and internal reflections. The same is true of large spessartite cabochon gems too, basically you get more gem weight for a reasonable price, the stone seems more fulfilling. Talented designers have always done wonders with gems like turquoise, opals, black onyx and the like - these gems are almost always cut smooth with no facets. Kaisilver offers large spessartite garnet gems in the 15 to 50 carat range, supply is limited in both faceted and cabochon form.
