Therefore, obsidian is solid before crystals can form. It is no ordinary stone, but nature’s glass formed from volcanic lava and hardened so quickly it formed no crystalline structure, when other elements become trapped in this process the stone takes on a “snowflake” appearance when cut and polished into a bead. Obsidian has a glass-like texture and is sometimes known as Volcanic Glass. The beautiful patterns of snowflakes that stand out of its black background are inclusions of gray feldspar and it is found in Utah. Open box (never used), Large hand formed on a heavy silver surround, priced to sell.. Make an offer! Tacoma, WA. The crystal particles trapped in the glass are a type of quartz called cristobalite. The three varieties of obsidian found are the snowflake, sheen, and rainbow obsidian. It is not considered a true mineral, as it does not have an entirely consistent chemical content and it does not form crystals. She has only one eye (possibly due to corruption) that's closed most of the time. Snowflake Obsidian is also called Gray Snowflake Obsidian as well as White Snowflake Obsidian. She also has no nose. Distribution Comments: Obsidian is formed by volcanic activity so it is found throughout western North America in areas formed by volcanic activity. Obsidian is formed volcanically when lava that is rich in silicic acid has been cooled extremely rapidly. Obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. The crystals that develop through devitrification cause obsidian to lose its conchoidal fracture and glassy texture. Snowflake Obsidian History Obsidian is a naturally occurring volcanic glass formed in swiftly cooling lava that has a high silica content. The intersections of these fractures can form edges sharper than the finest steel blades. With time, the respective glass is turned into a rock. snowflake obsidian crystal. It resembles snowflakes, hence the name. Especially the snowflake obsidian is considered a protective stone, which is supposed to protect its wearer from false friends, coming dangers, negative influences and black magic. She has a spiky white mane-like structure around her head, shaped similarly to the patterns scattered over her form, which mirror real-life snowflake obsidian. — Pliny the Elder, Naturalis Historia 36,67 (AD 77) Formation. These gorgeous Snowflake Obsidian Cabochons are free-form in shape and crafted in India. It can form delicate patterns across the surface of some obsidian specimens. Snowflake Obsidian is usually black in color, with white patches called Phenocryst. It is occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian can be formed in several different locations around lava. Obsidian Appearance. Snowflake Obsidian is a tall, bulky, warrior-like Gem. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian is an extrusive igneous rock. As such, it has the same general composition as the other variants. When lava cools more slowly, quartz crystals begin to form giving the rock a more textured, “snowflake” appearance. Snowflake obsidian is a product of a volcanic eruption. How is Snowflake Obsidian Formed? Instead, snowflake obsidian is best used in larger decorative pieces where its beautiful snowflake inclusions are much more noticeable. Visit gemdat.org for gemological information about Snowflake Obsidian. About A small, rounded piece of snowflake obsidian, roughly an inch in size. Snowflake Obsidian is a black, opaque stone with gray to white distinct markings. The volcanic glass occurs naturally. A variety of Obsidian A rock - a natural volcanic glass containing white 'snowflake' crystal patterns of the mineral cristobalite, originated due to partial crystallisation of the glass. Snowflake Obsidian is jet black with the distinct grayish-white snowflake patterns that Snowflake Obsidian is known for. Instead, the molten material immedately solidified into an amorphous solid called a "glass". Obsidian is formed when molten lava erupts from a volcano and cools rapidly. Snowflake obsidian is formed when crystallization occurs in the flowing lava. Native Americans discovered almost all of the obsidian locations in North America.
