📝 Material Overview, History, and Geology
Rainbow Obsidian is a volcanic glass prized for its colorful iridescent bands created by microscopic magnetite inclusions formed during cooling. When cut and polished, it reveals layers of green, purple, blue, gold, or red sheen that shift under light. The Jalisco region of Mexico is one of the most famous sources of high-grade Rainbow Obsidian, producing material known for its vivid multi-color displays.
Collectors and lapidary artists favor Rainbow Obsidian for its ability to produce dramatic freeforms, domes, and cabochons with strong optical effects. Though it may appear black in raw form, the hidden play of color makes each piece a surprise waiting to be revealed.
