jasper62 Pillar of the Community United States 2189 Posts	Posted 12/15/2019 07:48 am 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 Edited by jasper62 12/15/2019 09:35 am Report this Post to the Staff

mcstone Valued Member United Kingdom 179 Posts	Posted 12/15/2019 2:42 pm 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.

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 12/15/2019 6:22 pm 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. Report this Post to the Staff

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 12/21/2019 07:50 am 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.
