I've recently come back from a week's rigorous and exhaustive product testing...circle tahtians...9-11mm, very varied, not classically rated but great in a long strand on leather...
We take quality control very seriously, as you can see...!
Question...is that first pic of your tahitians in a swimming pool? If so, was the pool chlorinated? If so, how did the pearls respond? I've been fearful of wearing any of my pearls near a swimming pool, it would be so cool if I could do this without stressing out...lots of pool-time in the summer
Yet more testing.
Yes. the first pic is in a pool. I don't know how it was cleaned but it did not smell of chlorine nor was it salty..could have been UV. As far as I know pearls don't mind a quick meeting with very dilute chemicals. The problem is usually if they are on silk which will of course rot very quickly if often damp. If they are on a synthetic or caitlin's beloved fishing line then they should be fine (you could rinse them...and avoid very chemical pools which won't do you much good either)
