Amanda,
There are a number of forums on the net. I divide them into two classes, genunine forums and what I call "shill-sites".
One sort of shill is a person, normally a woman who works in a casino. Her job is to latch onto a high roller, usually a man, and use her charms to entice the mark to keep playing and losing money. When I first discovered this site I assumed that since it was run by a pearl company it was a Shill site designed entice consumers and drive traffic to the commercial side of the site. Diamondtalk and Pricescope are notable examples.
Jeremy is to be congratulated because, though he is without doubt, a merchant, he is also interested in deciminating true information. For the 8,000 years or so that we are aware of the gem trade's existence, secrecy and disinformation has been part of its stock and trade. Though it is an old habit and we can understand why it was important in the past, today it works against the interest of all honest merchants.
The more consumers know, the better. This is the age of information and like it or not there is tons of it out there, lots of it false. If we fail to get out the truth, we will suffer for it.
In my book I purposely excluded any discussion of and did did not include a chapter of akoya pearls. Why, because, in the words of a friend of mine and pearl expert, a majority of the akoyas in the market are "a highly processed fraud."
Though I don't share completely her opinions on "pearl plated beads" Zeide's posts are exactly on target. Beads with nacre thicknesses of 1/10th of a mm that are bleached white then dyed pink and will flake if scratched with a fingernail may be a great retail item but to call them pearls is to degrade the definition.
A few years ago, publicity surrounding the sale of a single emerald (The Fred Ward case) caused the emerald market to crash. It still has not completely recovered. All of a sudden consumers were made aware that in some cases the beautiful gem they bought was filled with polymers. W wouldn't want to be holding a big stock of thin skinned akoyas if and when that happens to the pearl market.
