Gemax Chelsea Filter
$35.00
Correct Chromium Filter. Stable & accurate results !!!
Some gemstones appear to change colour when viewed through the Chelsea 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 Chelsea 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.
