Black Sri Lankan limpet shell combined with two turquoise gemstones. 
I found the black limpet shell on the beach in Sri Lanka directly in front of the famous lazy left break. 
Turquoise is known for being a master healing stone and is intended  to remind you of tropical, turquoise seas 
They are set on sterling silver bands which have a hammered effect to represent the sea! 
Size N 1/2
