The chain is 18k. I believe there are no scratches or stains. I haven't used it much. I have the purchase card. How about it for everyday wear? The only markings are 4℃ 18K. The color is pink gold. The diameter of the top, including the round part, is approximately 0.4 cm. Total length is about 40cm. There is a round ring that allows you to shorten it by about 3.8cm. If you are very particular or looking for a perfect new item, please refrain from purchasing to avoid any problems. #Diamond #Diamond #4℃ #Sirena Azzurro #Necklace #Accessories #4°C #Urban Research #La Soeur #Magnolia12
