[QUOTE="Ded Driver, post: 535968, member: 12692"] If in doubt, first do a deep scratch to check it is not lead, & Brass will be much harder to scratch than gold. Find someone (or yourself?) that can do a very accurate volumetric test (find the exact volume). They are very clean nuggets so the volume can be taken as all metal. Then do a calculation on the SG of gold for the volume, & that should match the weight on scales if it is pure gold. Gold SG is generally around 19.3 [/QUOTE]
