These beads are not dyed (I check various ways) I have so far only made one bracelet with Swarvoski Crystal for myself to wear and I love them, they have good weight and are consistent batch to batch and when Requesting similar batch colors to make consistent designs Nikki made sure I got matching (within reason) and I am thrilled and requested different batch shade which she said should be coming in a few months Love them and I have ordered from stone dealers tried getting jade of this consistent quality and I have reordered these round jade beads in 4mm, 6mm, and 8mm. THEY ARE GREAT highly recommend for hole, size, and lot consistency thus far. Def re-order picture of the 4mm
