The crystals that i received were excellent. i just collect cool minerals and rocks here and there, and i found the quality of these crystals to be quite good. there is a clear presence of bismuth oxide, which gives the crystals the great color. the crystals that i ordered look great on display. i found no major flaws in the crystals that i received. a great deal if you're a collector or someone who just loves minerals and rocks. they look great under a good light source.
Awesome! My son who is collecting physical samples of as many elements as possible is thrilled! Thank you.
I love looking at touching this crystal. It's beautiful and tactile.
The colors are outstanding!
