Gem Testing Tutorial: how to use the hydrostatic balance instrument to determine specific gravity

This is my favorite test. Along with the refractive index, this test also provides a "number" to cross-reference. With a simple hydrostatic balance you can measure specific gravity and unlock another huge clue in gem identification. I’ll show you how to weigh a stone in air and in water, avoid bubbles, and apply the formula with confidence. I’m Nick, trained in colored gem identification at SSEF in Switzerland.
