In crafting this rear view mirror hanger I selected an inlay Celtic Cross, turquoise nuggets and bamboo coral rondelle beads. The turquoise and bamboo coral is real but I suspect that the materials used in the cross are either plastic or, at best, reconstituted. The cross has want-a-be turquoise coral, malachite, azurite and yellow jade. The reason, other than low price, that I suspect plastic is that the cross is warm to the feel. Stone is usually cool to the touch. The cross is 1 3/4" by 1 1/4". I added a total of 2 1/2" of turquoise and coral beads and a loop of Tiger Tail.
