Review: ✨️SMALL BUT PERFECTLY FORMED!! ✨️❤️🧡💛💚💙💜 - A stunningly beautiful and perfect bismuth specimen. This has well exceeded my expectations. The rainbow colour balance, the crystalline formation from every conceivable angle, the size. (Tip for those who's size expectations aren't matched: Read the dimensions, keep a tape measure handy and look! If size not given, ask! Photos of all crystals are exceedingly deceptive). I am, quite honestly, blown away by this little beauty and would happily highly recommend this seller if all pieces are equally finely created. I've seen what it involves to make these and I'm tempted to try myself but I'm doubtful I could produce anything as remarkable as this. Thank you so, so much 🙏🏼 ( And no, I'm not an influencer/ tester or person who makes anything out of writing this review. I am simply a lover of crystals, a trained crystal healer and when training, we were taught to look for the same ' clarity, brilliance and fire' as any other precious gem/ metal. This has it in abundance!)
Review: Beautiful and unique! - A Beautiful and interesting crystal which looks really unique. Mine was shades of blue and yellow, not the rainbow effect you see in the picture, but still very pretty. The crystal is packed securely in a display case, but you can take the crystal out of the display box too, if you prefer. The crystal also feels quite heavy and is cold like metal. The only negative thing I can say about this item, is that the large isn't very large. I was expecting it to be bigger, but for the price I can't complain too much.

### ⭐⭐⭐⭐ A little smaller than expected
*by E***A on 29 December 2022*

Smaller than expected, the picture I took shows its about 3cm instead of 4-5 like product description said it would be. Would be pretty easy to break as the bit in the middle was quite thin. HOWEVER it is very pretty and the person I gave it too really liked it. I dont know much about Crystal type things but would recommend. Also it arrived alot sooner than it said it would 👍🏻
