Help with mark on clasps of necklaces.

I am helping out over at the auction house. There is a coral necklace & a malachite bead necklace that are marked 14KG. I did a Google search & it said this would be 14 karat gold. Is this a true statement?

I apologize for the lack of photos, but I really just stopped by to pick up something I won Tuesday night & I had no intention to do any work.

 

It's supposed to be gold, at least. It if goes cheaply enough, it's probably worth grabbing.

 

Thanks!!

I likely won't buy anything. He has an estate lot of the real deal & some "costume".

Supposedly the guy was a jeweler & he made many of the pieces for her.

I am going to try to remember to bring my camera tomorrow to take some "drool photos".
