[QUOTE="WalnLiz, post: 33449, member: 147"] The Super Sluice is by far the best pan for dry panning gold, but, no pans out there are efficient enough to pan the likes of Sapphire, Zircon, Topaz, or garnet which are among the highest SG stones out there. By far the best method is a set of sieves, 1/4" and 1/8" is the best combo. Dry sieving is very common at all areas without water and almost as efficient as having water. Your quality gems like the ones above have a surface with a "waxy" looking finish, and generally dirt has difficulty adhering to more than a small portion of the stone. These gems also in most cases have what looks like cleavage chips of glass on various spots of the surface, and these throw a visible glint if light in the sieve after being dry sieved. Your Quartz crystals fall into the same category as the gems and are mostly clean or at least "Visible" when dug out of the dirt. Hope this helps, :) Cheers Wal. [/QUOTE]
