Intarsia Gemstone Jewelry - Intarsia is an art where they take precious gems and cut them into geometric patterns and piece them together to make one piece of gem material that will eventually go into a piece of jewelry. Gemstone intarsia is almost a lost art and rarely do you see it offered on QVC or Jewelry Television or any of the popular jewelry tv shows. Here you will find some of our one of a kind intarsia pendants and more.
