[Jeweler's Tools] Limited Edition Chelsea Color Filter Emerald 2-Piece Set

The Chelsea Color Filter is a gem identification tool that transmits deep red and yellow-green wavelengths. Even gemstones of the same color may appear different colors when viewed through a filter, so it is used as an aid when purchasing and identifying gemstones. This is a set of two items: the Chelsea Color Filter and an emerald . You will receive one of the eight emeralds shown in the photo.

Originally developed to identify emeralds, it has been used primarily to distinguish between green stones, but is now also used to distinguish between red and blue colored stones.
*Not compatible with all colored stones.

For example, emeralds and rubies, which are known to contain chromium, appear red when viewed through a Chelsea Color Filter.

However, the color and vividness can vary depending on the amount of chromium and other trace elements present, so some colors are difficult to tell.

*The color does not necessarily change due to the amount and balance of elements contained, as well as individual differences.
*In appraisal, the Chelsea Color Filter is merely an auxiliary tool and is not used alone to make a judgment.
