From my Unity collection this Marina necklace is exquisitely unique in design, I love it !
The clasp at the front is on a hinge which gives you the freedom to swap the drop if you fancy a change. You can wear the necklace with the clasp to the back or the side  to create  different looks. You can also add the matching bracelet to the necklace to give you a longer look.
This really is the "wonder woman" piece of all neckwear. This sterling silver  and aquamarine necklace is approximately 18" long, the  woven square  chain is 6mm wide. The drop is 3.5cm long.
