Large Lake Superior Iridescent Rock Pendant. Most likely containing translucent quartz and other minerals, this piece has many colors and very unique iridescent stripes in it, to go with its amazing glossy shine. This one is sure to be the eye catcher in the room. Each handmade Quartz stone pendant on this website is found by Greg, slab cut, shaped, and polished to a beautiful shine. No two are the same. Each bail is securely attached to the stone using very strong E6000 glue. Consider purchasing a 925 Sterling Silver Chain with this item.
