I found a ring metal detecting last week and noticed the stamping was a 0 then a dot 950 it weighs 4.0 grams. Is this platinum or a fake. Thanks

I believe it could be silver or platinum, or not. Most likely you will need to acid test.

Hi, in my experience palladium is commonly found at .950 purity and often will just be marked .950 rather than having a proper hallmark. If it is palladium will be slightly less bright than platinum. Palladium is also significantly less dense than platinum so a specific gravity test will tell you for sure, but at 4g I would guess it probably is.

0.950 could indicate the fineness of silver.
A platinum ring for a professional jeweler, would feel obviously heavy, because platinum is close to the density of gold.

I wish I had a clue.There are no other markings on the ring

Added a picture of a 14K Gold ring 4.6 grams along side a 1952 Dime with the ring in question. 4.0 grams

Pure silver is a bit too soft and weak for practical jewelry purposes, or for silver tableware.
That is why a small amount of copper is alloyed with silver. 925 fine silver is the most popular and practical.

For practical jewelry purposes, 950 fine silver is about as fine as you can go.
