WikiProject Gemology and Jewelry To-do:

I have made a substantial edit to the freshwater page, and I am certain that someone will request reference. I am currently writing an article for Gems and Gemology about the current state of the freshwater pearl industry in China. This article will appear in the next journal issue. The information in that article and this article come from research performed by myself and a writer from the GIA in Zhuji China. Here is a video log of the trip: http://www.youtube.com/watch?v=8uXeSb7i5X0 JPShepherd


[edit] Cultured?

Freshwater pearls are not necessarily cultured pearls. Scotland, Ireland, Austria, Germany and a number of other countries yield natural freshwater pearls, but not necessarily seawater ones. J.P.Lon 19:59, 8 October 2007 (UTC)

[edit] "...will only go through the treatment"

"These smaller factories perform the treatments [2] that are nearly universal to all freshwater pearls. The pearls are pre-treated in a warm and cold chemical solution and then bleached. The pearls that exhibit strong coloration will only go through the treatment." What does this last sentence mean? It's rather ambiguous. —Preceding unsigned comment added by Shadowcrow (talk • contribs) 11:35, 11 January 2008 (UTC)

[edit] Hybridize those two species?

I don't think they can hybridize considering they are in different subfamilies. —Preceding unsigned comment added by Ecoeric (talk • contribs) 21:48, 26 February 2008 (UTC)

That is incorrect. They are from the same subfamily. They are from family Unionidae, subfamily Unioninae, and from the same genus which is Hyriopsis. They can hybridize and produce fertile offspring.JPShepherd (talk) 16:27, 12 March 2008 (UTC)
