A quality microscope with 10x advanced balanced visual response zoom together with the magnification range of 10x to 45x. Features intensity light control, dark field, bright field, overhead light source, stone holder and additional 20x lens(optional). This immersion scope gives the possibility to perform immersion analysis by submerging a sample in liquid. If the stone’s refractive index is close to the liquid’s one, immersion makes the interior more visible by reducing the effects of refraction and surface reflection. This enables you to see a gem’s inclusions or color distribution more easily. Immersion is also necessary to see crystal growth structures, which might help you separate natural from synthetic corundum. Features like curved growth striae in flame-fusion synthetics, or separation planes in assembled stones, are often far easier to see when the stone is immersed.
