I saw this pair of Opal Boulder splits on a tray at a very crowded booth at the Tucson Gem Show. They were in a group of other Boulder Opals, but they were the only ones that were speaking to me. I had to shoulder my way in and ask politely, “May I see those”? Luckily, they were not spoken for so we have them! A Boulder Opal split is when a vein of Opal is “split” to make a left and a right stone. This is a very rare occurrence. The coloring reminds me of a beautiful blue sky. And they will do that to you too. I pictured just the Opals in 18K gold (at an inch and a quarter long) with a few bezel-set Diamonds like stars in the night sky. The ear clips are worn on the ear with omega clip backs.
