Apatite is an electric vivid blue unlike any other blue gemstone. The color is often described as "swimming pool blue" or "Windex blue" These 6mm 1.90ctw Apatites are from Madagascar and that mine has been closed now for years, so they are increasingly more difficult to find. They are set into sterling silver castings with butterfly backs. This is the type of gemstone that most likely will not be found at your local jewelers and is considered a rare gemstone. All jewelry comes gift boxed.
