Base Material...14kgf (Gold) Motif Material...Natural Stone This is a handmade item. I'm offering it at a trial price, hoping everyone will give it a try. Uses grandidierite and aquamarine. I've combined a beautiful blue-green grandidierite with a leaf-carved aquamarine, creating a simple yet cute design. Thank you very much! (*´˘`*) Shipping will be by regular mail, but for those who are concerned, I can change it to Nekopos for an additional 200 yen. Please send me a message.
