Identifying & Dating PD Jewelry: Expert Assistance

Question
This is a very pretty pin of apparent good quality.. I "piddle" in vintage jewelry and realize that this is a contemporary piece, but would like to date it anyway.
Do you know if the company's stuff is cataloged anywhere.

Answer
Hello Rudy and thank you for your inquiry. Do you have the full name of the company or just the initials ? I have not been able to locate a company with just the PD initials. Is this a vintage piece or more contemporary ? If you can give me more information, I'll be glad to check my listings again.  Thanks !
