The size of this piece is 1 ¼ “x 1 ”. Each pendant weighs 0.4 oz. which is the same weight as 2 quarters. You will be able to choose the attachment of your choice. Either 18K Gold Plated or Sterling Silver Plated. I make every piece myself in my glass studio & no two pieces are quite the same. Dichroic glass is unique in that you see different colors of the rainbow depending on the viewing angle. I also make other items such as key chains, tie tacks, money & belt clips etc... I also take special requests. Please just ask.Shipping is extra.
