    1. Better Than a Chelsea Filter

      If you like using a Chelsea filter for gemstone identification you will love these...
      A very useful set of filters for gemstone identification and can be used for both rough and faceted stones. The Aqua filter makes Aquamarine glow a strong green colour which easily distinguishes the difference between Topaz and other blue gemstones.
      Apart from assisting you to identifying Rubys, the Ruby filter has many other uses for red gemstones including Garnets. Pyrope garnets will appear brown through the filter and Rhodolite / Almandine garnets will appear grey.
      A gemstone filter set, definitely worth having in your tool kit!
