These will be mostly or all rounds, maybe some shapes. Selection will vary. I bought about 18,000 strands about four years ago, sure they would sell out in weeks. The rounds will vary from 4 - 8mm. 15 - 16 inches long. We pray that these are turquoise. Probably none of the "tuyrquoise" I've bought from the Chinese over the last few years has actually been turquoise.
