📝 Material Overview, History, and Geology
Mexican Velvet Obsidian is a rare and captivating variety of obsidian known for its velvety chatoyance and flashes of color—often appearing in rich green, gold, and purple hues when turned under light. Once imported in bulk during the mid-1900s, this material is now extremely limited, with most available pieces being old stock from the 1960s or earlier.
This obsidian gets its name from the soft, shimmering effect that resembles velvet—making it a favorite among lapidary artists and obsidian collectors. When cut and polished, it produces fantastic cabochons that truly stand out. Its reflective sheen and smooth cutting quality also make it fun and rewarding to work with.
Today, the original mine is largely tapped out, and only a small amount of Velvet Obsidian circulates on the market, with most fresh material being smaller trimmers and tumbling rough. If you're lucky enough to find a slab or chunk, it's worth grabbing—this material is gorgeous, rare, and highly collectible.
