This is a K10 white gold diamond necklace purchased from Jewelry Tsutsumi. I made a rather large purchase using a coupon when I registered for Tsutsumi's online shop. However, it's been over a year since I bought it, and I haven't used it. I thought it would be better to pass it on to someone who would actually wear it, as the necklace seems unlikely to see the light of day otherwise, so I'm putting it up for sale. Due to the circumstances of the sale, I don't want to sell it to someone looking to profit from the gold's market value, so I will not be listing the weight in grams. If you like the design, please wear it often. However, although it is completely unused, it has been stored personally, so please refrain from purchasing if you are overly concerned about its condition. Thank you. *The box is not included due to shipping costs. It will be carefully packaged and delivered with only the necklace itself. Please understand. *I am also selling a K10YG necklace of the same design in a different color.
