On my tests it reads in the nickel area on detectors. You sure it is not white gold. I have a electronic gold tester that I use for this stuff.

Are there any backmarks (hallmarks) of any kind?

I was with Boobie when he found it and he wrote a nice story about the ring. We and the owner are awaiting for it's publication in a magazine.
I have found two and I know platinum is extremely brilliant, I mean it is beautiful, and it makes silver look dull.
Platinum is also very heavy compared to gold rings, an three time more valuable

I have a friend that found one while water detecting and it was a size 16 ring, it was hugh, It went over my thumb, about a month later the owner called him and he returned it to him.

Anyway it came in as a 48 on my Cortez. Someone told me Platinum comes in low but actually it depends on the ring size.

Platinum Stamping: What are the marks inside my platinum jewelry? You're familiar with the gold standard, where 24k = 100%. The platinum standard is based on parts per thousand, where 1000 parts = 100%. All platinum alloys are derived from this standard. The two most common platinum alloys found in the US. 95% Platinum: This alloy is 950 parts per 1000 and 50 parts other metals. Common quality marks are: Platinum, Plat, Pt, Pt950, 950Pt, 950Plat and Plat950. 90% Platinum: This alloy is 900 parts per 1000 and 100 parts other metals. Common quality marks are: 900Pt, Pt900, and 900Plat. Typically platinum is alloyed with copper, iridium, palladium, cobalt, ruthenium, tungsten, gallium or indium. It can also be alloyed with rhodium, osmium or titanium but these are rarely used.
