This is a one off ring combining an amazonite gemstone of rare colour with a smaller moonstone gemstone. 
Amazonite is said to filter stresses and have a calming effect on the wearer.  Whilst the colour of the stone conjures up memories of tropical seas. 
Moonstone is said to be the stone of the moon, deep healing waters, and sacred feminine energies.  The moonstone brings calm, peace, and balance. 
Set in sterling silver on a hammered band which represents the sea.
