Wow, the long strand is very beautiful - looks to be of great quality. The other almost looks artificial in comparison and the pearls do not look like they match the age of the clasp.
you're saying the pearls look newer than clasp? and yes i think nacre thinning in some spot on these. It could just be that the nacre is very thin. An x-ray of the eBay strand could help determine more about it.
yes back to dentist lol
It is hard to sell used pearls for a decent amount. An insurance appraisal will give the amount that it would take to purchase a similar strand if you had a loss, but you might not be able to sell them yourself for that amount. So, there is more than one value. I would insure the good pearls and then wear the heck out of them!
