Kleine natuurlijke blauwe saffier kralen rond 2 3 4 mm facet geslepen stenen kralen voor het maken van sieraden ketting armband doe-het-zelf accessoires

The stone is natural, no doubt about it. The different arrangement of holes in the beads spoils the impression a little. Because of this, the threads are not even, and when making a bracelet, sorting and spacer beads will be necessary.

I don't know for sure if these are sapphires or blue tourmaline, but it looks quite impressive and is most likely one of the natural stones.
