Natural opal and diamond necklace. 18K gold, stamped K18 Approximately 2.5ct Please check the stamp. The focus was not good in the image, and I couldn't take a good picture, but the stamp is clearly visible. There is no stamp for the stone weight. Therefore, it is offered at a bargain price. Unused item. The price was about 80,000 yen. Both 18K gold and gemstones are rising in price. Take this opportunity, it's a bargain price. Gifting is also possible. If you wish, I will do simple wrapping! If you wish, I will also include a box! Thank you. Chain: 40cm service chain The material is K18 and K18 coating. Thank you.
