GAGG(Ce) Raw Materials

GAGG(Ce) (cerium-doped gadolinium aluminum gallium garnet) is a new type of scintillator crystal, which is often used in radiation detection in the laboratory. It has the advantages of high luminous intensity, fast decay and no radiation itself, and is currently widely used in the fields of medical treatment, security inspection and non-destructive testing.

This stone was still producing pixels and lenses yesterday for gamma-ray detection in a university laboratory, and we took them out of the production line today and selected small pieces that are suitable for gemstones.This substance is very expensive in industrial applications, with the finished product approaching the price of gold. It is usually cut into thin slices of only 0.1mm or made into grid-shaped inspection products.

Characteristics after cutting into gemstones:

As a gem, GAGG is very good. It has a hardness of 8.0 and a density of 6.63g/cm3, which is great whether it is used as a ring facet or a necklace main stone. It is a canary fluorescent yellow in color to the naked eye. Its fluorescence is very strong, and its most unique feature is that when we use an ultraviolet flashlight to irradiate it, it will emit a unique and dazzling yellow fluorescence. Even sometimes without ultraviolet rays, you can see its faint fluorescence only under indoor lights or sunlight.
