Thanks so much for your replies.
There is no clasp. It looks like the enhancement was attached on a thread.
So the freshwater pearls are generic. Would you please explain what that means. I’m assuming “nothing special”. Being that the necklace is 48” long I can understand that!
Any help is much appreciated.
The necklace measures 48”. There’s a small diamond near the top left of the loop.
HU on the back BUT the U is attached to the right vertical line of the H and 585 next to it.
The shape of the pendant looks like an L to me.
Thank you for any of your expertise.
