While in the past, the color black had negative connotations, black crystals are now appreciated for their grounding and protective energies. Here are the top 10 black crystals, along with tips on identifying them, their metaphysical properties and different uses:
1. Black Obsidian
Black obsidian is a natural glass formed from volcanic lava cooling rapidly. It has a smooth, glassy texture and is usually opaque with a black or dark greenish color. Natural obsidian may contain small gas bubbles or flow patterns.
Metaphysically, black obsidian is a grounding and protective stone. It can shield against negativity and absorb negative energies. Black obsidian is also known as a 'stone of truth' as it brings clarity by revealing secrets and hidden issues. Physically, it aids digestion and relieves pain.

2. Black Tourmaline
Black tourmaline belongs to the tourmaline group of minerals. It has a prismatic crystal structure and is found in long black striated crystals. The striations along the length of the crystals are a distinguishing feature. Like obsidian, black tourmaline has a smooth, vitreous luster when polished.
This stone has powerful metaphysical properties – it repels negative energy and protects the wearer from destructive forces. Black tourmaline also promotes self-confidence, power and spiritual grounding. Since ancient times, it was used as an amulet against dark forces.
Industrially, tourmaline crystals are used in electronic instruments and pressure gauges due to their unique electrical properties. Tourmaline is also mined as a semi-precious gemstone used in jewelry.
3. Black Onyx
Black onyx is a variety of the mineral chalcedony, which is a cryptocrystalline form of quartz. Natural black onyx stones have fine bands of white and black that create a parallel lined pattern. However, the black onyx sold in the market has usually been artificially colored by dyeing chalcedony.
Metaphysically, black onyx enhances emotional and physical strength and stamina. It is believed to increase willpower, self-confidence and discipline. Black onyx is also regarded as a protective stone that can absorb negative energy.
