GAGG Pixels, Yellow Lumogarnet Scintillator (Day Glow Fluorescence, Slight Phosphorescence) Stone:Incomplete Larger GAGG Pixel (fragment of a complete pixel) These were cut from aThese are pixels of GAGG, a type of hyperfluorescent lab created garnet which were produced for use as scintillators in PET scanners, CAT scanners or similar devices but didn't quite make the cut. We have complete pixel prisms, ones with cracks or missing areas, partial fragments as well as ones that have been faceted. The complete prisms measure 27x5x3mm and weigh in at 14. 5 carats on average. We also have had some faceted as bright and brilliant
