Hello, I am here in Oakland, enjoying the quiet afternoon.. taking a break from drilling and stringing blue baroque tahitian pearls....mmmm!
There is no question that the pearls pictured at the beginning of this thread are not Japan Kasumi pearls (they are Chinese fresh water pearls). Then there is the question about "pondslime" pearls. This is a term that Fuji Voll coined some years back (it is obviously not a market wide vocabulary term). At first I fought him tooth and nail about using this description, but I must say that now it has kind of caught on, and our customers for the most part have gotten past the initial shock, and now ask for them by name. (Personally, I find it a little refreshing when a product is described honestly, as opposed to glossed up to seem better than another)... So what we mean when we describe a pearl as being "pondslime" is when there is a mix of natural fresh water colors and often with a sort of golden green veneer coating the surface to add to it's luster or depth of color. It is an effect that is completely natural, no pearl processor would waste their time to dye a pearl these colors.
Here are four photos of some of the pearls I have here. I hope this helps.
The first photo: JAPAN KASUMI PEARLS (always bead nucleated) (fresh water pearls from Lake Kasumi-ga-ura). You can see that the two loose drops on the right have a sort of "pondslime" effect.
The second photo: BEAD NUCLEATED CHINESE FRESH WATER PEARLS
The third photo: BEAD NUCLEATED CHINESE FRESH WATER PEARLS, the texture of these pearls, is often compared to the texture of Japan Kasumi pearls, and thus it is common to find other dealers selling them as either "kasumi" or "chinese kasumi" pearls. I have even had other dealers try to sell them to me as that (and these are people who we have exhibited next to us for years, who have come and looked on in amazement as customers clammered for our *baroque japan fresh water pearls*).
The fourth photo: TISSUE NUCLEATED CHINESE FRESH WATER PEARLS, these are a great example of "pondslime". We realize neither the name nor the look of them is for everyone, but if they were, we wouldn't like them anyway! (he he).
So in the end a name is just a name.
Buy only what you love, that way you can be happy with it no matter what people call it.
Sorry to be late to chime in here, I got scared off by the "ethical consumer" thread. Too much to say to that, so I have been drilling and stringing the pearls that I love!
Enjoy and I hope this helps!
Cheers Sarah
