Unakite vintage tie tack natural cut semi precious stone

Unakite is a true rock: a composite material made up of multiple other stones. This gives unakite its familiar moss-on-brick appearance and makes it a popular lapidary material. The patterns, durability and affordability of unakite have also made it a useful stone for architecture--its most prominent use is trimming on the front steps of the Smithsonian Museum of Natural History in Washington, D.C.!
