This hoop is the lightest most wearable hoop. This imperfect oval hoop is a basic staple that looks super unique and is almost universally flattering. It is forged from one continuous piece of sterling silver 1mm wire and has a “tension” closure. The medium size is about 1-1/2 inches long and the large is 2-1/8 inches long.The gold hoops are gold plated sterling and the silver hoops are made from sterling silver. If you feel you might be sensitive to gold plating you can choose the 14k gold fill wire option.
