What can be mistaken for obsidian?
Obsidian, a natural volcanic glass, is often mistaken for other glassy rocks like flint, chert, onyx (agate/chalcedony), tourmaline, or even industrial slag, due to similar dark, glassy appearances, but true obsidian has a distinctive conchoidal fracture, high silica content, and lacks crystal structure, unlike many imposters which might have banding (onyx), grain (tourmaline), or gas bubbles (slag).What can be confused with obsidian?
Black onyx, Apache tear, black tourmaline, and lastly the black obsidian are a few examples of these. Due to the similar appearance of these stones, people often confuse them and can't tell the difference.What else looks like obsidian?
Obsidian-like stones: Helenite — a man-made blue obsidian gemstone made from Mount St Helens volcanic ash.How to tell if something is obsidian?
To tell if something is obsidian, check for its glassy luster, smooth texture, conchoidal fracture (shell-like breaks), and dark color (usually black, brown, or gray), but know it can sometimes show sheens or be translucent at edges; look for tiny, well-distributed gas bubbles (not large, spherical ones like slag) and remember it's harder than glass but can still scratch it. Obsidian is volcanic glass, so it lacks true crystals and feels cool to the touch.What rocks are similar to obsidian?
Rocks that look like obsidian, a black volcanic glass, include other glassy volcanic rocks like Pitchstone (higher water content) and Tachylyte (basaltic glass), plus minerals like polished Hematite, Black Tourmaline, and even dark Agate/Onyx, though these differ in texture (crystalline vs. glassy) and magnetism; man-made glass/slag can also mimic it but often has bubbles or unnatural colors.Obsidian: Spiritual Meaning, Powers And Uses
What are the black stones that aren't obsidian?

Fake obsidian often looks like unnaturally vibrant colored glass (blue, red, green) or slag, showing large, round, visible gas bubbles and being completely transparent, whereas real obsidian is usually dark (black/brown), opaque or slightly translucent at edges, has tiny, elongated bubbles (often microscopic), and exhibits a distinct "conchoidal fracture" (scoop-like breaks) with a glassy luster.How much is 1 gram of obsidian worth?
One gram of obsidian is generally worth very little, often just pennies ($0.005 - $0.50) for common black types, but rare colors (like rainbow or fire obsidian) can fetch much more ($1.00 - $5.00+ per gram), with prices depending heavily on color, clarity, processing, and whether it's rough or polished. For bulk or craft use, it's very cheap (a few dollars per kilogram), but unique, gem-quality pieces command higher prices due to market demand, not inherent material value like precious metals.How to check for obsidian?
To identify obsidian, look for a glassy, smooth texture, shiny surface, and typically dark color (black, brown, grey), but be aware of colorful variations like snowflake or rainbow types; it breaks with extremely sharp edges in curved patterns (conchoidal fracture), is generally opaque but can be translucent at thin edges, and is harder than glass but brittle. Real obsidian usually lacks visible spherical bubbles, unlike slag.Is obsidian heavy or light?
The density of obsidian is 2.55 g/cubic cm. It means it is heavier than water and dense medium as a mass.How to tell black tourmaline from obsidian?
To tell black tourmaline from obsidian, check for striations (lines) and opacity: Tourmaline has parallel, ridged lines and is fully opaque, while glassy obsidian is smooth with a conchoidal fracture (curved breaks) and can be translucent at thin edges. Tourmaline feels heavier and has a wood-like or metallic sheen; obsidian is typically lighter, has a glass-like shine, and feels cold.What rocks can be mistaken for obsidian?
Most obsidians have a composition similar to rhyolite and granite. Granites and rhyolites can form from the same magma as obsidian and are often geographically associated with the obsidian. Rarely, volcanic glasses are found with a composition similar to basalt and gabbro. These glassy rocks are named "tachylyte."How to identify jet stone?
To identify jet stone, look for its lightweight feel, warmth to the touch (not cold like glass), and its tendency to produce a distinct brown streak when rubbed on unglazed porcelain; it's fossilized wood, so it should be deep black, may have faint wood grain, and won't fade in the sun, unlike some fakes. A professional can use a hot needle to check for a coal-like smell, but this risks damage.What does black tourmaline look like?
Black tourmaline looks like deep, inky black, long, prismatic crystals with distinct vertical grooves (striations) and a rough, sometimes earthy texture, often with a subtle sheen rather than a glassy shine, feeling heavy and solid, and unlike obsidian, it doesn't usually have smooth, reflective surfaces but rather natural imperfections and parallel lines.What is the rarest color of obsidian?
Fire Obsidian is easily one of the most rare forms of obsidian known to exist. Since fire obsidian gets its color from magnetite, it does require bright light, with the stone turned the right direction, to get the color to light up. Under normal conditions, it will appear black.Is it legal to sell obsidian?
Yes, you can sell obsidian, but its value and legality depend on quality, quantity, and sourcing; common black obsidian is cheap ($1-30/lb), while rare rainbow/sheen varieties fetch much more ($50-200+/lb), and you need permits for commercial collection on public lands, as personal collection permits forbid resale. You can sell to rock shops, online gem dealers, or lapidary suppliers, often by the pound or in finished cabochons/tools.Who cannot wear black obsidian?

Black Obsidian is easily compared to the Agate stone. With similar chalcedony traits, the only difference between the two stones is the form of bands found within each stone. Obsidian typically has black and white parallel bands, while Agate has multi-colored curved bands of color within each stone...What is a shiny black rock that looks like glass?
Obsidian doesn't look like your typical rock. In fact, it looks more like dark glass than a rock you'd pick up in your backyard. That's because obsidian is volcanic glass. It forms when volcanic lava cools so quickly, there's no time for crystals to grow.What is the rarest black gem?
The rarest black gemstone is often considered to be Black Opal, prized for its intense, holographic "play-of-color" against a dark body tone, making it extremely valuable and scarce. Other contenders for rarity include Black Diamonds (Carbonados), potentially formed in space, and collector's gems like Cat's Eye Scapolite, known for its unique optical effects and rarity.
