Gem Filter Set
- Ruby Filter for discriminating among red stones such as Ruby, Spinel, Tourmaline, and Garnets.
- Aqua Filter for differentiating blue gemstones, separating Aquamarine from Topaz and other blue gems.
- Synthetic Emerald Characterization 2 Filter Set which allows one to quickly separate synthetic Emeralds (flux or hydrothermal) from natural Emeralds. Used in conjunction with the Chelsea Colour Filter, this filter set greatly simplifies the recognition of synthetic emeralds. Just remember, "Red, Red, Drop Dead!".
- Bead Buyer's 4 Filter Set designed for the simultaneous examination of a number of gemstones, either as a string of beads or a parcel of loose stones. The idea is that if all the beads or stones in a set are of identical material, they will appear the same when viewed through any filter in this set.
Characterization and identification of Gems by the use of color filters has always been an appealing approach because of its affordable simplicity and the ease of examining multiple specimens. Featured here is a combination set that includes a Ruby Filter, Aqua Filter, Synthetic Emerald Filter, and a Bead Buyer's and Parcel Picker's Filter Set.
