There are a variety of different shapes and sizes of coral beads on the market. These corals I have found on the ever intriguing jewelry markets of Thailand. The red coral is more common but the green one is something I have only bumped into once and this was in Thailand. (Still think I should have bought more) The color of the green is perfect. It is beautiful. So here are two necklaces and a bracelet.
Off to make some silver jump rings.
