Synthetic Emerald Filter

0.50 LBS
  • Product Description

    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.

    This set 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!"  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.

    Also included is a Support Filter for the easy differentiation of Russian hydrothermal products. 

    To use the set, first make sure the stone to be tested is a natural or synthetic Emerald, using the Chelsea Colour Filter and/or other method.  Then illuminate the stone and hold the filter close to the eye.   A natural Emerald will generally stay greenish or lose body color.  On the  other hand, a synthetic Emerald's body color will generally turn pinkish/reddish. 

    Full instructions are included.  This product typically ships within 1 business day.

    1. Very nice addition to my tests.

      You simply look through the lens close to your eye with the lights on and it will indicate if your emeralds are likely synthetic or natural. My tests were positive for natural emerald gemstones. on Feb 3rd 2021
