European Gold Hallmark Question: I recently purchased a ring from a local antique store whom purchased the ring through an estate auction.

Hallmark: A History of the London Assay Office

Price: $55.00

Its band is a very soft (light) yellow gold color. It has a hallmark of P531.

I have looked up as much as I could find, and all I can find is what 12kt and 14kt numbers are in European hallmarks.

So, if this is an European hallmark, than it seems it would be about 13.5 part gold, but I can’t seem to find anything that states there is such a gold combination.

I have also seen the letter markings stating the years in could have possibly been made in, but the “P” text does not seem to match any that I found.

The “P” is also not enclosed in a box. Any help would be so appreciated.

Thank You!

Platinum ring Question: I have a platinum ring and on the inside it says PLAT with a star after it.

I was trying to figure out how pure the platinum is that was used in it because I am thinking about selling it and although at one time I had a certificate for it from the original jeweler I have moved and cannot seem to find it.

I think the purest would say 950 in the marking but I can’t seem to find out what mine is I don’t have alot of time to go have it appraised on my days off I am usually pretty busy so I was just wondering if anyone here might be able to help me.

I bought in in Philadelphia and I live in California now and I had a certificate the jeweler gave me with it but it is lost in the move somehow.

Any help would be appreciated.

Thank you and have a great day!

Platinum Bracelet Quality Question: I bought this bracelet about a year ago and was told that it’s “Platinum”.

Price: $74.81

I do not know what the number for Platinum is, but I do see a stamped number 585 or 586 - can’t make it out 100%.

Would you please tell me what is the correct number.

Many thanks. Maryann - New York

Platinum ring?

Question: Hi David, Is a ring with the stamp “PALAD” - platinum?

I think it stands for paladium which I believe is in the same group of metals as platinum?

Many thanks, Bek
