Triple stacking ring, comprised of three individual bands that can be worn in any combination.  There's one shiva's eye shell that I found in Vietnam, a moonstone triangle and a very rare piece of blue multi coloured seaglass found on Seaham beach.
All three rings are on sterling silver bands with hammered effect which represents the ripples of the sea. 
The spiral shell is often called ‘shiva’s eye’ and is regarded as a very important symbol especially in India.  The ‘shiva’s eye’ shells are said to awaken a sense of adventure, change and can eliminate fear!  These shells were found in Vietnam so will connect the wearer to the Pacific Ocean.
Moonstone is said to be the stone of the moon, deep healing waters, and sacred feminine energies.  The moonstone brings calm, peace, and balance
Each ring individually measures U.K. size N 1/2 but when worn stacked together they will fit like a U.K. size M.
