These iolite 8mm gemstones will used in an Angel Chaplet. Beautiful. Wish they had a bit more bluish hue to them. They are a bit darker than the photos shown for the listing thus the 4 stars. Still, they are a beautiful gemstone, lovely in their creation from the earth. I believe I will add a more vivid translucent faceted blue gemstone for the larger beads in the chaplet to bring out the color in the iolite. I will also use diamond chips to space the gemstones. When I am done, these iolite stones will shine, and the chaplet will be stunning. The seller shipped them promptly and they arrived safe. The description was accurate. My expectations met.
