I purchased this new from ZOZO about a year ago, but I haven't had a chance to use it and have been storing it. Official details below: 【DAN】 All materials are made of sterling silver 925, with a solid design. Adjustable sterling silver 925 ring & bangle series! Necklaces and anklets are also adjustable in length, making them unisex for both men and women. The gold color is 18K coated on sterling silver 925.
