would work on Swarvoski crystals?
You can use the battery operated bead reamer on Swarovski crystals, just be sure to keep the tip and the crystal under water to prevent the diamond grit tip from wearing down and make sure you have fresh batteries in the reamer to prevent the tip from sticking inside the bead. The reamer does cause the hole on the crystal to become frosted, so that is something to keep in mind. If you’re gluing the crystals, the frosted end helps hold the bead in place and the glue seems to prevent the end from looking frosted.
