Ruby Filter is a filter that is extremely useful in differentiating red stones such as Ruby, Spinel, Tourmaline and Garnets from others that might look similar in comparison.
For gemstones which have intense red fluorescence, such as natural ruby, synthetic ruby, and red spinel, they appear very bight red under the ruby filter. (As the three all show bright red under the ruby filter, need to use the eyes, magnifying glass, fluorescence, polarizer for further testing. Ruby belongs to the uniaxial crystal, it shows polarization. Spinel belongs to the cubic crystal, it does not change under polarizing. Synthetic ruby shows more bight color under long wave UV fluorescence. In addition, you can also distinguish them according to their difference in inclusions and dichroism).
For gemstones which have no or weak fluorescence,, such as red garnet, the red tourmaline, they appear dark gray or black under the ruby filter.
Operation:
1. Place the stone in natural light or other white light, reflected or transmitted light both ok.
2. Hold the filter close to the eye, observe the color of the stone at a distance of about 30 cm.
