The 2 heavy liquids I use for immersion are methylene iodide and benzyl benzoate. Heavy liquids used for SG are labor intensive as the slightest contamination results in the need to recalibrate the liquid. One normally keeps a series of "floaters" in the liquids to make sure they are working properly.

LST Heavy Liquid background and properties

At its optimal working density at 2.85 g/mL, LST heavy liquid has a viscosity of 10 cP and so has less of the viscosity related separation problems associated with the older polytungstates such as SPT. In practice, LST Heavy Liquid allows faster grain separations and easier filtration.

It is measured as the ratio of the density of the gemstone to the density of water, and is expressed as a number that indicates how much heavier the gemstone is compared to an equal volume of water. Scientifically, specific gravity is defined as a ratio of the mass of a given material to the mass of an equal volume of water at 4 degrees centigrade.

Identify Your Rock: Key Mineral Traits (With Photos)

To figure out a rock or mineral's density, you'd compare its weight to its volume. For instance, gold is super dense. That's why a small piece of gold feels heavy. Think of it like this: if you have a small object that feels super heavy, it has a high density. But if that same-sized object feels light, it has a low density.

How To Identify Gemstones

Heavy liquids are liquids that have a known specific gravity, they typically are available in sets of five to six separate liquids each with their own SG (specific gravity) usually ranging from 2.57 to 3.32. If a stone is placed in heavy liquid and it floats, the SG of the stone should be close or lower then the liquid that it is placed in.
