A dark gemstone, often mistaken for black diamond or other similarly colored stones, is a mineral composed of magnesium aluminum oxide. Its deep hue arises from the presence of iron, zinc, or other trace elements within its crystal structure. It possesses a hardness rating of 8 on the Mohs scale, rendering it a durable option for jewelry and other decorative applications.
This material’s appeal stems from its brilliance and affordability when compared to other black gemstones. Historically, it has been used in various royal settings, often confused with more valuable gems like sapphires or rubies. Its availability and relative ease of cutting make it a popular choice for contemporary jewelry designers seeking a dramatic and sophisticated aesthetic.
