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.

 

HOW TO USE A RUBY FILTER

 

Hold the filter an inch or two from the eye. Shine a light on the stone with a strong light bulb or torch. The stone may appear to change colour. The filter must be held near to the eye but there is no need to hold the filter close to the stone, even items in showcases can be examined providing they are lit by strong lights.
