Thank you for viewing! This is an Itoigawa jade pendant top. The material is 10K gold. It's a deep blue from the Nyukonsawa area of Itoigawa jade. This is a brand new, unused item. It will be sent after the stone is set with prongs. A necklace chain is not included. It can be prepared separately. If you have any questions, please feel free to ask in the comments section. I have other items for sale, and I can combine shipping, so please let me know. I hope you will consider it. Thank you. #ItoigawaJade #Itoigawa #Jade #Hisui #Nyukonsawa #Blue #PendantTop #10KGold #New #Unused #FreeShipping
