Jason1 ... I agree ... I prefer the Specific Gravity test, also ... dry weight divided by wet weight, will give you the S.G. of any metal

So can you measure accurately enough considering there is only .05 gram difference between gold and tungsten density?
That gold maple he weighed varied that much.

I've found specific gravity reliable to 2 decimal places. (Measured in grams/cubic centimeter and with adjustment made for density of water at room temperature.)

Tungsten is not your problem though. Platinum alloys beautifully with copper and gold, and because it was so much cheaper than gold, was used in knockoff sovereigns and francs.

Not everyone want to submerge their metals in water.

Alternate options is Digital scale & Vernier digital caliper.
Be familarize with your metals and their sizes.
