Replying to @kingKongSchlong today we are talking about obsidian. Obsidian is volcanic glass that cooled quickly at/above the Earth’s surface. Due to its amorphous structure on an atomic level, it appears shiny or glassy and breaks with conchoidal fractures. This specific sample of obsidian is actually super cool because it has porphyritic quartz phenotypes within it! - #obsidian #geology #igmetpet #igneous #volcano #rocks #geologymajor #earth #science #womeninstem #conchoidalfracture @Taylor Sw

GIA (Gemological Institute of America) on Instagram: "Obsidian is a volcanic silica glass that forms when lava cools so fast that crystals don’t have time to grow. There are several beautiful varieties of obsidian, including snowflake obsidian and rainbow obsidian (seen here). Rainbow obsidian is unusual in that it contains layers of inclusions that are oriented parallel to the lava’s original flow structure. When light reflects off these layers, it is broken into spectral hues creating iridesce
