It is a diamond shape necklace made of concrete (natural concrete color) with scandinavian moss (biol. reindeer lichen) hanged on metal chain.
A size of element is about 2 x 2 x 2 cm, lenght of chain- 80 cm.
As it is handmade it can differ a little from the one presented here.
Reindeer lichen is a kind of plant (exactly plant mixed with mushroom) which takes the water from the ear (you don't need to water it). Even after years it won't change and it will look the same :)
