Author Topic: can 750 be plated? (Read 645 times)

parsec · « **on:** December 17, 2011, 19:21 »

I didn't find this detecting, I noticed it in a bag of jewellery at a market. I picked up a gold tooth, several marked plated bits of jewellery and this little item that grabbed my attention pretty quickly. It is marked 0750 but I can't imagine it is solid as well it weighs 2oz. So my question is do they mark plated jewellery with 0750?

oh, sorry for the white ballance, I took this indoors, but it is the appropriate colour

cheers, shaun.

Parsec
see the number above 750?
the 18 K

there is your hint

parsec · « **Reply #2 on:** December 17, 2011, 20:01 »

yeah, I know it is 18kt, but do they mark plated stuff? I guess I am asking did I just find a $5 piece of jewellery or a $2500 one?

cheers

You could be on the money parsec.

it is heavy, I might get to it with a knife and see what is hidden

Goodbeard · « **Reply #6 on:** December 17, 2011, 20:10 »

If it was plated then it would probably have a mark like "lined", "gp" or "rg". Check with a magnet, if it doesnt stick it still might be gold. If it only going to be scrapped you could put a deep scratch in it to see what lies beneath.
My vote is 18k of sweet gold.

alimo88 · « **Reply #7 on:** December 17, 2011, 20:10 »

what is it?
more pictures please if you can stop shaking
is something written on the edge of the clasp?
do a density test please. you are killing me

Correct me if im wrong, but isn't like white gold just ordinary gold with a coating of rhodium? Could something similar be going on here?

alimo88 · « **Reply #9 on:** December 17, 2011, 20:17 »

wrong
different alloy gives it a white colour
more silver and platinum in it I think
there is a nice pic of gold alloys on the web some where
i.e. rose gold may have more copper??

I have to admit I am semi turgid

well done

and tooth gold is 14 K i think

I bet you paid less than the tooth will earn you

parsec · « **Reply #11 on:** December 17, 2011, 20:26 »

here are a couple more pics.

Yep I paid less than just the tooth is worth, so anything else is a bonus. This thing though has my attention

Parsec can I have LxBXH?
I would like to work out how many cm cubed it is

it's probably by one of those dodgey Lalique, Cartier or Faberge clowns

Lenth 200mm

thanks for the help

alimo88 · « **Reply #16 on:** December 17, 2011, 20:54 »

all the ones I have seen on the web like that are vintage or antique
be carefull

I think they are called cuff braclets

lets have some info on that makers mark

Goodbeard · « **Reply #17 on:** December 17, 2011, 20:56 »

Thats about $2400 worth where I sell my scrap. A couple of weeks ago it would have been $2690.

Here's hoping gold price rise again soon!! $:-\$

parsec · « **Reply #18 on:** December 17, 2011, 20:58 »

indeed goodbeard, bring on 2k/oz

alimo88 · « **Reply #19 on:** December 17, 2011, 21:21 »

those dimensions would give you over 200 grams of gold
but on the plus side. that is from the dimensions only with no air gaps
that's exactly why Archimedes shouted Eureka (or something)
you have all the tools need to do a density test at home if you get restless.
and another plus is that no one would want to wear a 200 gram bracelet so I vote for gold still
Good luck

parsec · « **Reply #20 on:** December 17, 2011, 21:27 »

Thanks.

Good point about the air gaps, but I think it doesn't add up. Will have someone look at it on Monday. Still happy with the day though, and fingers crossed on this one.

thanks again for your help

Hi Parsec, I hate to dampen your spirit, but need to show you a couple of pics of a massive 18ct chain, stamped in 3 places on the chain and clasps, that i found detecting at the beginning of the year. I was sooooooooo dissappointed when the only gold i could see on it was a little piece of plating around the clasp. I thought i had found a $5000 18ct chain, but it was copper junk. Those market people generally know there gold, i have found, be very careful. I wish mine had been gold. $:-\$
