This is a K18 necklace from over 50 years ago. It has become dull from being stored for many years, but I believe it will become a beautiful gold color after cleaning. It has a design that is not often seen nowadays, with intricate craftsmanship. The only hallmark is the one for the country (flag-shaped diamond with percentage purity). The weight can be measured to 0.1 grams, but the value fluctuates slightly. There is an error of about 25.0-25.5 grams, so please be aware of this before purchasing. No returns accepted. No claims, no returns. Length: 81.5 cm #K18LongNecklace #K18IntricateNecklace Material: K18 (18 karat gold)
