In my opinion, real pearls go on real silk cording and are knotted. That's just the way they are supposed to be. Nowutimeen?
Billy ;o)
Real pearls knotted on real silk cord is the traditional way to do them. Knots prevent the pearls from rubbing against each other and IF the strand breaks, at most you only lose a pearl or 2. However - silk is organic, it stretches and subjecting it to sunlight, body oils, normal body dirt and sweat causes it to decay. It is not moisture proof, which also causes rot/decay and breakage. IF they are "good" sea/cultured pearls, if they are antique or vintage and you have the original clasp and want to maintain their value then, by all means, knot them on silk. If it was my choice for a vintage piece, I'd pay someone to knot them.Re-stringing and/or knotting pearls yourself could reduce the value of antique or vintage pearls.
From a bead store owner's perspective, silk is a pain to stock. Because it's an organic thread, it does have a shelf life. We have no demand for silk thread here, so a minimum order from our supplier would sit on the shelves and literally rot before we sell a card or two!
My DH (aka "the jeweler") bought me a strand of pearls before we got married and I wanted to string them to wear at the wedding. (This was years before we started the bead store.) I wanted to add some gold or crystal as highlights and was told by DH in no uncertain terms that it was to be pearls on silk - PERIOD! "Those aren't any old 'gaudy beads', those are GOOD pearls!" he said.
I couldn't find any silk in any of the local stores (see two paragraphs above for why) and really didn't want to pay by the inch to have them strung professionally. I finally used Beadalon Dandyline (which is a braided cord that is UV, abrasion and moisture resistant and has almost no stretch. (I sneaked in a couple of gold spacers for a little "kick", too! <LOL>) I didn't knot them, though I should have. Regardless of the "should haves", I've been very happy with the result, but I AM considering re-stringing them with some of the gorgeous AAA grade amethyst faceted rondelles that we just got in for spacers.
However, when stringing or restringing freshwater pearls, my opinion is that just about anything goes. Crystals, seed beads, strung on flex wire, thread/silk or whatever strikes your fancy - even the dreaded stretch. ::shudder:: One of the best flex wires when it comes to pearls is the SoftTouch wire. In .010" it is SO soft and flexible, it's like thread. The SoftFlex company touts that you can even knot pearls with it. .010" diameter is fine enough to go through the smallest hole, too - without a needle!
::disclaimer:: no relation to or association with SoftFlex, just a store that sells their products once in a while.
Anyway - that's my 2 cents on pearls and stringing.
