Investigative Reporting: When is a "Pearl" not a Pearl?

Thanks to JewelryBizGuru for bringing this article and resource to my attention. I was a bit surprised by it but ultimately glad that I read it.

I'm still investigating the environmental and ecological implications of harvesting freshwater pearls, perhaps Mr. Roskin will write about that at some point. In the meantime, his article When is a "Pearl" not a Pearl? is a very interesting read.
