Crystals

Bony amber is a rare type of amber containing fossilized animal remains. This precious material forms when tree resin traps small creatures before hardening over millions of years. Paleontologists prize bony amber for its ability to preserve ancient DNA and soft tissues.

Anyolite is a rare metamorphic rock composed primarily of green zoisite and black hornblende, often featuring vibrant ruby crystals. Found mainly in Tanzania, this striking gemstone is prized for its unique appearance and used in jewelry and ornamental carvings. Its formation requires specific geological conditions, making it highly sought-after by collectors.

Biotite is a common mica mineral found in igneous and metamorphic rocks. It forms dark-colored, sheet-like crystals with perfect cleavage. Composed of potassium, iron, magnesium, aluminum, and silica, biotite is an important indicator of geological processes and environmental conditions during rock formation.

Binghamite is a rare, golden-brown mineral composed of manganese silicate hydroxide. Found primarily in Minnesota, it forms fibrous masses with a silky luster. Named after Florence Bingham, this mineral is prized by collectors for its unique appearance and scarcity.

Ammonites were prehistoric marine mollusks that lived in spiral-shaped shells. These extinct cephalopods thrived in ancient oceans for over 300 million years before disappearing alongside the dinosaurs. Fossils of ammonites are prized by collectors and provide valuable insights into Earth’s geological history.

Ametrine is a rare variety of quartz that combines the purple hues of amethyst with the golden tones of citrine. This unique gemstone forms when two distinct color zones grow together in a single crystal, creating a striking contrast. Ametrine is primarily mined in Bolivia.

Boji stones are unique geological formations found in the Mojave Desert. These circular stones contain both positive and negative polarity, creating a balanced energy flow. Believed to have healing properties, they are used in crystal therapy and meditation practices to promote physical and emotional well-being.

Black coral, a rare deep-sea organism, forms tree-like colonies in ocean depths. Prized for jewelry, it’s actually an animal, not a plant. Despite its name, living black coral is often colorful, only turning black when polished. Harvesting is strictly regulated to protect this slow-growing species.

Blue amber, a rare gem found primarily in the Dominican Republic, exhibits a striking blue color when viewed in sunlight. This unique hue results from fluorescence caused by hydrocarbons within the fossilized tree resin. Highly prized by collectors, blue amber is often used in jewelry and decorative objects.

Bismuth is a metallic element with unique properties. It forms colorful, iridescent crystals and has a low melting point. Used in cosmetics, pharmaceuticals, and electronics, bismuth is non-toxic and has the unusual characteristic of expanding when it solidifies, unlike most metals.
