Its green coloration forms due to iron and trace element inclusions, such as Fe²⁺, Fe³⁺, and magnesium, which create a greenish tint, or from tiny gas bubbles and microscopic mineral inclusions that scatter light. With its rich, glassy luster, green obsidian makes for striking cabochons, beads, and carvings, and when polished properly, it achieves a mirror-like finish that enhances its vibrant hues.\u003c\/p\u003e\n\u003cp data-end=\"908\" data-start=\"638\"\u003eTraditionally, green obsidian has been associated with personal growth and truth-seeking.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eChemical Composition\u003c\/b\u003e\u003cspan\u003e: Volcanic glass (rhyolitic; about 75% SiO₂ with Al, Na, K)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eGrade\u003c\/strong\u003e: Lapidary Grade\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eAppearance\u003c\/strong\u003e: Opaque\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eCracks:\u003c\/strong\u003e None\u003cstrong\u003e\u003cbr\u003eInclusions\u003c\/strong\u003e: None\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eApproximate Size of\u003c\/b\u003e\u003cb\u003e 1 pc\u003c\/b\u003e\u003cspan\u003e: 7cm x 6cm x 3.5cm\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eApproximate Weight of 1 pc\u003c\/strong\u003e\u003cspan\u003e: 160g\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003ci\u003e\u003cspan\u003eRough is rough.
