Various sizes of hard to find Cobalt Blue colored lab created spinel rough for faceting and gemstone creation.
***This material is becoming harder to source. The material that we are getting typically has cracks towards the top and will have quite a bit of crazing (small cracks on the shell).
Items that are significantly cracked are noted and discounts are applied.
The faceted gem is for example only, and is not included.
If you would like to see additional pictures of the piece(s) you would like, please feel free to contact me and I will be happy to provide additional pictures for you to review.
