These 1960’s or 70’s vintage glass cabs are uncirculated old stock. They have a black base with wavy mauve pink stripes with a translucent moonstone effect. They’re unfoiled stones, and they measure 10x14mm each.
Some of the photos make these stones look as if they’re scratched, but they’re not. The highly magnified photos picked up every speck of dust and flash of light in the background.
This style is also available in black with white stripes, and black with green stripes.
