Calibrated Fantasy Cut Laser Garnets, Neodymium and Cerium YAG usfg but eventually they were pushed

but eventually they were pushed too far and the ends blew off

slowly building up transparent gemmy crystals in a variety of colors and forms

I don't know what causes this color but it is very unusual

These were grown in a lithium molybdendum flux mix

These are lab created rubies produced in the Soviet Union back in the 1970s or 1980s

Calibrated Fantasy Cut Laser Garnets, Neodymium and Cerium YAG usfg but eventually they were pushedThese are calibrated fantasy cut laser garnets (Nd+Ce: YAG) with concave facets. They come in violet and gold (depending on the ratio of Ce to Nd) and have variable fluorescence including yellow, pink, red and violet. The laser garnets were grown varying chemistries, creating different colors ranging from pink to orange to gold to green, And the fluorescence has multiple colors too, with some stones showing both pink AND yellow at the same time.
