The surface is smooth and reflective, sometimes showing a faint sheen or translucency at the edges when held to light. Rounded and palm-friendly, the Black Obsidian has the cool, glassy feel characteristic of the material.\u003c\/p\u003e\n\u003cp\u003eBlack Obsidian is traditionally associated with protection and grounding, and is often used for releasing or working through difficult patterns. Many people keep it by the door, hold it during shadow or release work, or place it in a grid as a protective anchor. Its deep, absorbing colour and long history as a ritual and tool stone make the Black Obsidian a staple for grounding practice.\u003c\/p\u003e\n\u003cp\u003eEvery Black Obsidian piece is natural volcanic glass and unique, varying in sheen and surface character from the example shown.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Properties\u003c\/strong\u003e\u003cbr\u003ePrimary Focus: Protection \u0026amp; Grounding\u003cbr\u003eSecondary Focus: Transformation \u0026amp; Growth\u003cbr\u003eChakra Association: Root\u003cbr\u003eZodiac Sign: Scorpio, Sagittarius\u003cbr\u003eChinese Zodiac: Snake, Dragon\u003cbr\u003eRuling Planet: Pluto\u003cbr\u003eElements: Earth, Fire\u003cbr\u003eMohs Hardness: 5-5.5\u003cbr\u003eStone Family: Volcanic Glass\u003cbr\u003eMaterial: Natural Black Obsidian\u003cbr\u003eOrigin: Mexico\u003cbr\u003eForm: Tumbled\u003cbr\u003eFinish: Polished\u003cbr\u003eApproximate Size: 20-30 mm (0.7-1.3 inches)\u003cbr\u003eApproximate Weight: Single Stone, 100 g, or 1 lb (454 g bulk quantity)\u003cbr\u003eListing: Single unit, 100 g or 454 g as selected\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeological Information\u003c\/strong\u003e\u003cbr\u003eBlack Obsidian is a natural volcanic glass of silicon dioxide, amorphous rather than crystalline, with a Mohs hardness of 5 to 5.5. Its jet-black colour comes from iron, magnesium, and other mineral impurities suspended in the glass. Obsidian forms when silica-rich lava cools too quickly for crystals to develop, and its conchoidal, shell-like fracture produces edges that can be sharper than surgical steel, a property that made it one of the most important tool materials in human prehistory for over 700,000 years. Sources include Mexico, the United States, Iceland, Italy, Japan, Turkey, and Armenia.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuturaSol Standard\u003c\/strong\u003e\u003cbr\u003eEach natural stone is selected for its authenticity, geological integrity, and energetic clarity.
