Galt & Bro has designed an eternity ring that actually fits over your knuckle in all kinds of changes in weight and weather! It is 18k yellow gold and diamonds, as you would expect from a piece of fine jewelry. But there is enough stretch and flexibility to it that it glides over your finger and then gently returns to its original size, fitting snugly. No need worry about those few extra pounds or the humidity in the hot weather. It measures 3 mm wide with one carat of high quality diamonds. Ease, comfort and beauty are the keywords for this unusual piece. Fits finger sizes 7 to 11.
