This book was created for the jewelry designer such as myself. Have you ever purchased gemstones, beads or cabochons at a bead show then to go home and realized what you had purchased is not labeled and you can't remember what it's called? I have done this, including online purchases, it was very frustrating to realize you've design a beautiful jewelery piece but now you are unable to write a description all because you don't the name of your bead, gemstone or cabochon. This book shows you a color picture and gives you the name of each stone to help your jewelry business.
