Popular Black Gemstones
Onyx
Onyx is one of the most recognized black gemstones. Known for its smooth texture and striking bands, this gemstone comes in shades of black, gray, and brown. With its hardness ranking of 6.5 to 7 on the Mohs scale, it’s a favored choice for both jewelry and decor. Traditionally, onyx was believed to protect its owner from negative energies, making it an important stone in various cultures.
Obsidian
Obsidian is a naturally occurring volcanic glass formed from rapidly cooled lava. It possesses unique characteristics, including a glass-like luster and sharp edges, which made it valuable for making tools in ancient times. Varieties like rainbow obsidian and snowflake obsidian feature beautiful iridescent colors or white patterns, respectively, adding to their demand in modern jewelry designs.
Black Tourmaline
Black tourmaline is often hailed for its protective properties. Composed of complex boron silicate minerals, it enhances positive energy and dispels negative energy. Its unique chemical composition results in a beautiful, opaque black rock that is often seen set in silver or gold jewelry. The metaphysical community frequently utilizes it in meditation and healing practices.
Black Diamond
When discussing black gemstones names, the black diamond stands out due to its rarity and distinctive allure. They are less sparkly than traditional diamonds and lack the clear brilliance. However, black diamonds are gaining popularity in modern jewelry design, often appreciated for their unique aesthetic and creative use in engagement rings.
Black Spinel
Black spinel can be identified by its vitreous luster and is often confused with black sapphire or onyx. However, it is more refractile and shows a higher brilliance. It varies from opaque to translucent, making it a valuable gemstone in the jewelry industry. Because it is more affordable than diamonds, many jewelers are choosing black spinel as a substitute.
Black Sapphire
Black sapphires are valuable with a hardness of 9 on the Mohs scale, making them a great option for daily wear. Their striking deep black color commands attention and they are used in high-end jewelry pieces, including engagement rings and statement necklaces. Their density exceeds that of other black gemstones, making them a durable choice for any collection.
