This piece of obsidian just makes it into the "golden sheen" variety- it has large gas bubbles here and there that give it a gold translucence, especially when held up to the light. Obsidian fractures in conchoidal designs, with sharp edges and rounded curves. It's glassy, with no crystals, having been formed from extremely viscous lava that cooled quickly.
