This beautiful pc is made with hypersthene natural c grade stone which has mohs hardness 5 to 6. I did tumble wash some beads and got every bead bit different from each other... few had shiny silver glitter layer , few had shining blue light under sun just like labradorite..(hypersthene is also called velvet labradorite). I will post a video of same.
