The Chelsea Filter is a specialized gemological tool designed for authenticating and distinguishing between real and synthetic gemstones such as emeralds, aquamarines and sapphires. This filter allows only deep red and yellow-green light to pass through, making it ideal for identifying certain colored stones and detecting dyes.
Main advantages:
-
Differentiation between genuine and imitation gemstones: It allows the identification of emeralds and their imitations, with genuine emeralds usually showing a red or pink color, while most imitations remain green.
-
Dye detection: Effectively detects dyes in some gemstones such as dyed green and blue chalcedony.
-
Usability for multiple stones at once: The filter can be used to evaluate several stones simultaneously, which increases efficiency.
Use: The filter is intended for gemologists, jewelers and collectors for use in mixed batches of stones and jewelry where it is necessary to distinguish genuine gems from imitations and detect the presence of dyes.
Limitations: Some emeralds, especially those from South Africa, may not show the expected pink color, which may require additional tests to confirm authenticity.
Test results: The filter demonstrated high efficiency in distinguishing between genuine and imitation emeralds and was effective in detecting dyes in gemstones.
