Crystal Quartz Cushion Gemstone, AA-Grade

This AA-grade cushion crystal quartz features a clean, clear quality and high luster. The bright formation of these crystals makes them a great choice for a variety of jewelry designs such as earrings, pendants, and rings. One of the most common minerals, quartz comes in many varieties and colors. The two main categories are macrocrystalline—which are usually transparent, and crystals are visible—and cryptocrystalline, which appear translucent or opaque. The many varieties of quartz each offer distinct characteristics and, according to folklore, their own powers and purposes. The cushion cut is a classic style; it combines features of the oval cut with a deep cut and large facets.
