Jewelry, Gems, & Minerals/ring marking


I have a heavy,Silver colored metal ring with PL not ststamped or engreaved but instead looks to be etched. There is no other markings.  Is this a Platinum ring or what do I have?  Any help would be Appreciated

Dear John,

Thanks for this question. The markings do not fit regulations for the USA.  I suspect the mark is to indicate the manufacturer or is meant to confuse, as in fraud.  The best thing to do is have the metal tested by a jeweler.

PL is no acceptable as a marking because it confuses Platinum and Palladium. Marks for platinum are pt and plat often with a numeral to indicate amount of platinum in the alloy. Palladium uses PD as the marking. You see, the marks do not use letters found in both metals names. No "t" in palladium and no "d" in platinum.  The potential for confusion to the buyer is why PL is not accepted as a metal quality mark.

I hope this helps!  God Bless.  Thomas.

Have a question about jewelry repair or working with precious metal jewelry and gemstones? For many years up to December 31, 2010, I was a working professional bench jeweler, involved everyday with setting stones in mountings, designing and making jewelry, repairing and limited custom manufacture. If you work with jewelry as a hobby or as a profession, I might be able to help. I deal with the retail business, not mass production. Ask privately if you wish. See the box for that: It keeps your question between us. Please DO NOT ask MAKER'S MARKS, but metal quality marks are fine to ask. Please DO NOT ask diamond prices. See a gemologist for that.


I have extensive experience in design, service and making of jewelry. I deal mostly with precious metals and gemstones but work with many materials as needed and usable to create an artistic design. My experience also includes freelance photography and photographer of jewelry and similar items for a former employer and individuals. Design of custom items requires reading the desires of the client and being clear on what can be done within that framework...then fulfilling the transition of idea to reality. Effective communications is essential in a working designer/producer and customer relationship.

Education is English/Physics! Started in human resources, to advertising, to, what a road. I have had formal training in jewelry work and many shared experiences with top grade jewelers. We just never know were we will go or be. Follow your best, your dreams, with some discretion! Don't let the work tear up your body along the way as it has mine.
