No Hallmark & a Hallmark

[Hwhydah17172002]

I found a couple oddities.. Any help will be apreciated. Thanks in advance. One ring tests out at 18K but I am curious about the date if possible. It was the Mother's ring that was missing all of it's stones... & The other ring that tests out at 10 K but is it white Gold, seems to be prety heavy. weighs in at 11.1 grams. but the funny thing about it is it is very pitted so thats what is throwing me off, and also shows some glimmer of yellow gold on the face? Crazy stuff for sure. Paladium? Platinum? does the saltwater corrode that type of metal after a very long time in the water? No markings in the ring, Need help... Thanks Whydah

For consideration I'll add:
I have cast ring by centrifuge and by vacuum -----minor mistakes in heating, impurities, metal recast too many times& poor alloyed metal can cause porous castings. Many times the band is the most porous. For a save-instead of just scrapping and starting over---some people will just plate the object to hide the severe pitting. The plating will eventually come off.
MDers that find a lot of jewelry-especially in the salt- should occasionally find a green spot on silver or a black spot on white gold (aside from any solder joint) due to one or more of the reasons listed above.

Always test your metals. When I made jewelry ('77-'95) anyone could purchase any type of Hallmark or benchmark.

I would not think saltwater would bother the Platinum group metals.
