About Synthetic Emerald Filter
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 Synthetic Emerald Characterization Set which enables 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!" Do not buy an Emerald which shows red through both the Chelsea Filter and the Hanneman-Hodgkinson Synthetic Emerald Filter unless you intend to purchase a synthetic flux grown product.
