	Green and rusty GOLD « on: December 17, 2015, 10:50:58 pm »

Does gold rust or turn green?
Well it does (or looks like that does) in Melbourne Victoria Australia.
I got lucky this week.Perfect weather for detecting in the water.
I found All the usual things and two gold rings.
The first one when was found it was just a loop of rust.
It turns out to be a 9crt gold ring.
The second it’s just green. But you can see the gold coming out.
I will post a pic when it’s cleaned.
They where found in the water in the bay with my P.I Garrett sea hunter Mii.
I wish I had an underwater VLF like the ML 3030 to test and see if they would be picked-up.

9k gold is composed of more than half an alloy meaning it is 15/24 of it is some other metal. That is more than 2/3 of its content. Perfectly alloyed gold where the metals are kept heated for a good long while allowing molecular bonding won't corrode. Gold that is not alloyed properly where the atoms of metal are bonded correctly will corrode but normally only in spots. Stampings of 9kt are also done on brass by the street vendors of several Pacific Rim countries who shall remain nameless to protect the innocent.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

Congrats Nickel, Any Gold is Good Gold, The 3030 won't go as deep as your seahunter, so you had the right tools for the Job,

I always give the rings that I am in doubt the sniff test.
Smell a penny or some brass after you rub it and then see if the ring smells like copper or brass.
The composition of the rings has much to do with the corrosion on it. If it's been in the water for a while it might do that.

Some of the gold around here coming up from Mexico plated or low K marked as 14K. Some are even Magnetic. Rascals !

GD I think you are right.
As you say 9k is 2/3 made of an alloy and not gold. Been in the salty water for 50-60 years and next to a peace of iron that corrodes it doesn’t help ether.
I just didn’t know and I was surprised to see it.

RR my concern it’s not the depth of the detector but its ability to discriminate iron.
The place I detect its literally covert by iron. If the 3030 can mask it with out loosing the gold that’s the detector I want.
If it does mask the “rusty” rings then its not good to me.

At 9k, you do have some gold there, just not much in relation to the alloyed metal. Still a nice find but it's not surprising that it has tarnished or gathered oxidation to the other metal. Like I said, if the alloying process is done exactly right with proper molecular bonding, there won't be corrosion. There will be some tinting to the gold over time. Copper tints the gold orange to bronze in color. Silver tints it pink. Bronze tints it an overall blue-green. That is the extent of the corrosion on a perfectly bonded alloy ring.

If, as you suggest, it is very old, then the alloying process may not have been that good and the molecular boding might be "lumpy" instead of perfectly smooth. You get the idea.
