Lost triangular ish stone and silver necklace pendant

[Seemiddy]

This is a bit of a long shot.

But.

My lovely mum lost her necklace pendant, which is of great sentimental value, in east Dulwich. She lost it a long time ago, but it didn't occur to me to post here to see if anyone found it. If you happen to have found it and know where it now is please do get in touch.

It's a dark stone in a silver setting, about an inch high. I've attached a bit of a bad photo.

It'd be so amazing if it was found. It's so greatly missed.

Thank you.
