If you don't mind destroying the quartz, you can find out if you have gold in your quartz by doing an acid test. Place your quartz in a glass jar and cover it completely with white vinegar. The acid in the vinegar will dissolve the quartz crystals in several hours, leaving only bits of quartz attached to the gold.

As the gold and quartz dust melt, the gold will fall to the bottom of the solution. Most attendant minerals will quickly oxidize and float on the surface of the metal. This forms slag which should be removed. You should wear a respirator during this process, not everything in native gold is safe once it reaches higher heat.
