Reputable gold exchange or appraisers in western WA.

I'm sitting on some Montana gold nugget but do not know the purity. Anyone have experience with dealers/appraisers west of the mountains?

When I was over that way, I used Northwest Gold and Diamond. Technically in Renton, but down the street from IKEA so it's kind of at that intersection of Renton, Kent, and Tukwila.

I think most pawn shops can do scratch/ acid tests to determine KT/purity. also seen some with the gun. I know Alaska is usually about 22kt or better and usually the cream of the crop. I wanna say the rest of the US was 18-20kt at the most but obviously varies from piece to piece

I believe Porcello Jewelers in Bellevue can accurately test for purity with the GIA acid test. They may be able to xray it too unsure.

Thanks all, great advice and suggestions. I followed hkcavalier's advice and contacted http://www.nwgoldanddiamond.com/

Great information, great experience, and Mark seems like a really decent guy. Plus, he had some good suggestions for my construction project!

Did you sell the nuggets? Some are worth more then scrap price.

Sounds like the OP has already offloaded his nuggets.... but I thought I'd throw this up here for anyone else.....

These guys have onsite assay capabilities for weird mixes or unknown purity precious metals.....

Unfortunately, they only pay ~80% of spot, but it gets you out of the assay fees and turnaround time. They'll pay 90% if you set up an account with them.

I've got some platinum and palladium I need to offload and these guys seem like the only ones that can deal with it on the 'spot'.

Called into NW G&D to see what their rates are, but they lack onsite assays.
