Those horrible Tahitians have been smuggled out for a long time.
On one of the Tucson Pearl Walks, Judi McC, Jeremy, and I went to the "tent shows" at GL&W, where there is an acre of freshwater pearls- commercial grade.
Judi took a photo of one of the Tahitians we saw there. It could not have been uglier, but that was close to 10 years ago.The photo is on Pearl-Guide somewhere, maybe in a Tucson Gem Show thread....
I agree the ugly ones will start showing up on eBay! A dab of near-matching nail polish covers a lot of holes.
I did that to my cheapo enormous Ripple pearls and wore them to H and J's wedding. Other wedding guests complimented me, but didn't notice the holes (which were gaping -in a couple of cases, the bead showed before I painted it) until I pointed it out and joked about it with them.
The colors were great on these beads, but the holes made them cost about $100 on eBay. Since that is the only ripple necklace I'll ever be able to afford, I embraced its flaws.
I just love those bi-color, ringed pearls from Tahiti - maybe more will show up.
