I've seen and lost wax cast 14K and 10K Yellow and Pink Gold and these
pictures look much more tarnished than I would expect. Alan Black "Murray Peterson" wrote in message ... Ignoramus27444 wrote in : I received a "gold chain" as a birthday present, two months ago.

I make jewelry as well, and in my experience, it seems to depend on skin chemistry. My wife can't wear any 14k gold -- it turns even blacker than what is seen in the pictures. |

I took a look at the pictures.
The 14k stamp on the tab appears to be machine done. Now, these ends can be obtained prestamped, but are actually made of 14k. In the pictures, both the chain tip and the clasp are discolored to the same extent as the rest of the chain. Most fakes I've seen have either a poorly stamped mark or are a cheap chain with a 14k tag and clasp. Either this was produced by a highly organized bunch of fakers, or something else is the problem. You haven't been wearing this in a hottub or swimming pool, have you? Paul K. Dickman Ignoramus27444 wrote in message ...

For very high quality scans (including enlarged pictures) of the chain, see http://igor.chudov.com/tmp/gold-chain/ (click on the thumbnail images to enlarge). Can this possibly be gold? I am going to sam's club tonight and will ask their jeweler also. I think that the person who gave me this present got screwed. -- --------------------------------------------------------------------------- - char*p="char*p=%c%s%c;main(){printf(p,34,p,34);}" ;main(){printf(p,34,p,34); } "It's never too late to have a happy childhood." |
