Two gold bands? Help with marks please

Wild guess - it was plated with 18k gold over a base metal

 

This is the only thing I could find for Traudel Jewelry:

The Traudel is the owner

The 18 is purely fraud. There is no method for depositing 18K electrically. The remnant of plate doesn't even look like gold.

 

Not after the cufflink thread discussion about finding nuts and bolts and bullets in jewelry boxes! Anything is possible.

 

Hi,
When I bought my house I found two very heavy gold chains marked with 14kt. I was a little excited until I realized they were brass plated over some base metal. The previous owner had rented out the attic to newly arrived illegal immigrants. I guess they were cheated out of their money for the chains.
I found a nice sewing basket at a sale. Along with the buttons were silver charms, baby teeth and some adult partial plates and coins. You never know.

I once bought a junk bag holding a busted necklace assembled by some child. Most of it was nothing in particular, but.... In addition to some sterling beads was an enameled sterling pansy pendant ... which sold for around $50. I paid $3 for the bag, give or take, and got that back on scrapping the beads. Then again I've also gotten things that were full of nice marks that were junk.

 

Yes you CAN electroplate 18K gold on a base metal.Its 75% gold but its so fine a plating that its not worth the time and effort as the plating will rub off in time.

Thank you Miss Information

And what pray tell metal dissolves the same as gold?

 

Why are you so SNARKY??? I was just letting folks know that 18k CAN be used for plating

 

"Miss Information" ??????????????
So anyone else on this board can give their reply and information, but when I do I get attacked? Just like on the eBaay board, I really don't know what is your problem???????????????????????

 

If 18K gold is dissolved in a liquid capable of dissolving it, the 3/4 that is gold will act completely differently electrically than the 1/4 that isn't gold.

When you spout misinformation it should be countered.

 

HA HA HA HA HA HA HA HA HA

 

Learn about basic titration

 

If you can plate with 24k, and I've seen that done all the time, you can plate with 18k too. Now what were we arguing about again?

 

If 18K gold is dissolved in a solution capable of dissolving 18K gold, the gold will be separate atoms from the other 25% of nongold material. Gold does not bond with other metals to form molecules. They will not be electrically attracted the same to the item you wish to plate. 18KHGE is a spurious mark. 18K plate can only be applied physically.

 

This is just off the top of my head since I have not done electro-chemistry since school, but if there are both gold and silver ions in the plating bath, both the gold and the silver in the 18K will pass to the plated object though due to the slightly different electrochemical potential of the metals, in slightly different proportions to the original alloy.

I don't think snappish sarky posts are much of an ornament to the new forum.

 

Its the various salts used. I will put this to rest after I post some links to those who wish to understand the process of electroplating.
