This elegant inlaid opal necklace enhancer will add flash and fire to a pearl or bead necklace, cord, or omega chain. The opal is bright with shimmering greens, with flashes of blue, framed in a sleek modern design. A single small diamond adds a little spark to the opal’s fiery display. I took pictures of the enhancer both under photo floods and with flash to show how the colors shimmer and change with the light. I also added a picture showing how stunning it looks on a pearl necklace (the pearls are NOT included). The enhancer is in marked on the back “18k” and with another mark that looks like “100.” It is about 1.25 inches long. This vintage piece is in excellent condition with only very minor surface wear. If you want a to add a striking new look to a necklace, this exquisite and unusual opal enhancer is for you!
