RARE Kornerupine Gemstone Lot | 3mm to 3.4mm Round Faceted Stone | Z229
RARE Kornerupine Gemstone Lot | 3mm to 3.4mm Round Faceted Stone | Z229
A lovely lot of four round faceted kornerupines in a bright sea green-blue. Kornerupine is one of the rarer collector and designer gem species in active circulation — production is limited and fine facetable rough is scarce. Finding four stones of consistent color, diameter, and weight in this variety is not a casual occurrence. These gemstones do have inclusions that can be seen with the eye, but it doesn't not impact their beauty, brilliance or color.
Kornerupine remains largely unknown outside collector and specialist designer circles, which means it offers genuine rarity and distinction in finished pieces. It has no synthetic or simulant counterpart in commercial production. Buyers and wearers are unlikely to encounter it elsewhere, and its color in fine material is competitive with far more expensive gem varieties. For designers building a differentiated inventory, kornerupine is a credible choice on both rarity and optical merit.
Kornerupine is not treated. No heat enhancement, fracture filling, or coating is applied to this species. Color is entirely natural.
