Gold/Silver rings, do they get a halo like coins in the ground

[musky8it]

Post from many experts in here talk about that halo around a coin thats been in the ground awhile. And if you compare test of an old buried coin compared to a fresh buried coin, the reading on a Ace 250 will not be the same. For testing purposes for myself, to see what buried rings will read. I am wondering if fresh buried gold/silver rings will read the same as rings that been buried for a while.

I know its probably a dumb question, but can't learn without asking ??? Do rings get that halo like coins do? From photos of rings people find in here is doesn't look like rings change colors like coins do so I thought maybe the don't get that halo like coins do. The reason I ask was because I was going to bury some rings I have to see how they would read on my 250. So when I am out I would recognized them better. I tried air bench testing rings, but I don't think that can give the same results as ones buried, right?

silver ones do & low k gold ones do in very very bad soil/ salt beaches to but the higher the k the gold is the less halo it gets. also digging the ground up & putting something in it then refilling the hole will change the signal a little due to the disturbed ground. hope this helps
the bigger ring is 9k gold & had a lot more corrosion on it, the smaller ring is 18k & has no corrosion they were both found in the same area

Yeah man, gold nuggetts are the same way, too. They'll give a good signal at depth under ground, but after you dig 'em up they won't signal as deep in an air test.Happy Hunting!

Nothing fresh buried reads the same as old buried due to an effect known as Metallurgical Phenomenon as your detector is reading a lot more than the target. Silver will form a halo and some very low karat gold but high karat gold does not oxidize and leach into the soil. And air testing proves little except your detector is doing what its supposed to do and just gives you a general idea how it might perform under ideal conditions. No one detects in the air.
