KORITE produces two types of gemstones: 1. Ammolite Naturals: These stones have a hardness of 3.5 on the Moh’s scale, like that of a penny, and are discovered and polished with minimal treatment. These gemstones can be used for pendants and earrings only. 2. Ammolite Triplets: These gemstones are calibrated to a precise size to fit in jewellery settings and are covered with a quartz crystal cap increasing its hardness to 7+ on the Moh’s scale; like that of a steel nail. This increases the stones durability and makes it ideal for all categories of jewellery.
