All the gemstones I have bought from The Bead Traders has been outstanding compared to another large and common gemstone trader here in the US. Seems that quality control is a lot more hands-on here than by other comparable traders. I am really pleased with the Tourmaline gemstones. They vary a little in thickness, but not much in measured size. The finish and quality are very good. I will buy from Bead Traders again.
Great selection, reasonable prices, like the choice of lower cost USPS 1st class shipping. I keep filling these reviews out, but never get the 20% off coupon.
