Some of these pieces are very beautiful with nice flash, some aren’t as flashy, and some are pretty small. Most of them are the same size as shown in the picture but I did get a couple very small ones, not quite “palm stone” sized or with very little flash. Overall, they are very nice and I’m happy with them but there are a few pieces that weren’t quite what i was expecting. Also I weighed the bag and it was exactly 1kg! I got 12 pieces in my bag.
