INTRODUCTION

Some gemstones appear to change colour when viewed through the RUBY Colour Filter. This colour change helps identify many gemstones, distinguishing ruby from paste; distinguishing garnet (though not all garnets) emerald and aquamarine from paste. The Ruby Filter also distinguishes many manmade stone such as cobalt-blue glass and blue synthetic spinel from natural blue stones. As with all gem testers, care must be taken since nature does not make gemstones to standard formulae and variations exist.

 

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.
