This chunky piece of Selenite weighs nearly 70g, which in Selenite density makes it as thick as your average small ruler and a half inch wide. It's about 4 inches long.
We received this Selenite stick as part of an old crystal collection which we recycled. It has a bit of scuff here and there. Photos will show it well. This is just normal handling scuff.
We use Selenite in our crystal collections to soak up and disperse bad vibes, but it is a soft mineral and scuff reasonably easily. I did think about splitting this up into smaller pieces but I can never be sure which way it will fracture.
