These broke while attempting to wire wrap them so I emailed asking for a replacement as I was working on a customer order. I said they could charge my original card if they had saved it. Then one of the chrysocolla broke as well. So I emailed again. The reply was simply that chrysocolla is a soft stone and any pressure can break it. No replacement, no acknowledgment of my first email. The other 11 earring pairs were fine and I’ve purchased from them at shows for over 15 years without a problem. I expected better customer service when there was an issue.
