Bracelet Markings: Identifying 'PR ST C' - Jewelry Authentication

Question
I have a bangle bracelet marked PR ST C and then it has another C that is facing the last C.  I have other jewelry that has Pr ST CO on it so I know the difference.  Can you help me with this?
Thank you,
Dez

Answer
Hello Dez and thank you for your inquiry. I have searched my resources and cannot locate any designer/manufacturer with this mark. The CC at the end is what throws me. I'll be glad to check with some of my other jewelry associates and see what I can find and I'll definitely let you know. Sorry I couldn't help you at this time.
