This is a gorgeous ring and very heavy. The top is covered in pave diamonds. The designs are braided rope etched in the silver. It is solid sterling silver. It looks exactly like it was made by John Hardy, but I did not see any specific maker's mark. Maybe someone else will know more about this unique ring. It is stamped 925 in a circle. Size 6. It has over 10g of silver. This ring is being sold for over $1,000. This is a great price!
