    • 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. Using it is as simple as holding the filter close to your eye, look at the stones, examine your gems, and reveal there's true identity.
