Very highly polished, when you hold your crystal up to the light, you will discover so much beauty. There is depth to this crystal as well as stunning phantoms inside like clouds. The surface is very smooth to the touch with a few tiny bumps here and there.
 
The crystal measures 1 and 3/4 inches long by 1/2 inch wide with a black cord with a clasp in the length you choose.
