I came by a strand of low-risk "turquoise" beads last weekend, strung with dyed branch bamboo coral. They're all close to 10mm long, and breaking a bead shows that the color is all the way through. There's a nice color variance, and the shapes remind me of Chinese, though the color had me thinking of American at first. Any feedback on these?
