Description
The jadeite filter is a specially designed gemological tool that is used to identify and distinguish between natural and synthetic gemstones, especially for the detection of certain red, blue and green stones. Also known as the Chelsea Filter, this filter was originally developed by Anderson and Payne in 1934 and is widely recognized for its ability to detect synthetic spinels and colored gemstones.
Main advantages:
- Differentiation between natural and synthetic stones: Effectively distinguishes between natural stones and their synthetic imitations, including synthetic spinel.
- Dye detection: It allows identification of the use of dyes in some types of gemstones.
- Universal use: The filter can be used at a distance, which makes it possible to view the stones even in windows illuminated by strong light.
Use: Filter is ideal for gemologists, jewelers and collectors who need a reliable tool for quick and accurate gem identification when trading or evaluating stones.
Limitations: The filter has a limited ability to accurately distinguish between natural and synthetic emeralds, which may require further testing for definitive identification.
Test results: The Chelsea Filter has been tested on a wide range of gemstones and has shown high efficiency in identifying synthetic spinels and detecting colored stones.
