[QUOTE="Heatho, post: 122484, member: 487"] The fluid bed 1mm gap underneath the expanded mesh is 1 reason why, it's quite ingenious actually, it will create slight upward pressure, enough to get rid of lighter materials and let sapphires settle to the bottom, just needs a bit of a shake now and then to help it along. What works for Gold won't necessarily work for gemstones. Walbankers are proven as working very well for both, you won't see many upset owners who have built it right. [/QUOTE]
