hello everybody, never really been into pearls but have been given these from my mum to try evaluate. She got them off her ex boy friend who bought them with a bag of stuff from a savers shop (they sold things from people who have died and tragically had nobody to leave there stuff to) about 10 years ago, apparently they where worth around $2500au when they where looked at (around 10 years ago) im not sure to much else about them, they are all very circler without many flaws that you can see from that naked eye standing away, they feel kind of sandy but smooth at the same time it also has 8 what I think are diamonds and a name staped on the back but I cant tell what it says, also it looks like afew have lost there shine or faded (ones closest to the link that has some green moss type thing on it) any help would be greatly appreciated
