Need Help Recognizing a logo on necklace please.

Good morning. Need help Identifying a logo on a necklace please. Any info would be greatly appreciated. It is approx. 18" long, it is really pretty but I have not been able to find anyone who could identify the logo.

On another issue, is anyone familiar with pearls? I have several and some are gritty on the teeth but that's all I know.

 

The ones that feel gritty to your teeth are at least genuine nacre on the outside. The grittiness can be very subtle, so you will probably want to do the 'tooth test' again on the others, but if they feel glassy compared with the ones that are definitely gritty, glass is probably what they are. What is it more specifically that you want to know about pearls? I'm sure among the dedicated joolies we know quite a lot. Without seeing the pearls (including the drill holes), there's no way to apply that knowledge.
