I had this purchased for me as a commemorative item about 20 years ago at a jewelry store. It was quite expensive. I used to love it, but I've decided to sell it. A K18 diamond pendant like this seemed to be rare. The back of the diamond setting is stamped with "K18" and "1.045". The chain cannot be removed. The chain is Venetian. The chain length is 38cm. An appraisal certificate is included. I will send it in a jewelry case with an outer box. I hope someone will like it. Please understand this is a pre-owned item. Also, returns are not accepted to prevent item substitution. The photos and product description are all-inclusive, so please consider purchasing after you are satisfied. Discounts are negotiable.
