Faceted Er-Nd Soviet Laser Garnets, Calibrated Color Change (Orange-Pink) YAG Gemstones

Faceted Er-Nd Soviet Laser Garnets, Calibrated Color Change (Orange-Pink) YAG GemstonesThese are faceted stones of an unusual experimental laser garnet from the Soviet union, codoped with Erbium and (likely) neodymium. The base color ranges from orange pink to purple pink, and they color change from more orange to more pink depending on the light source. This is a new material for us from an old collection, a 40 year old failed experimental laser garnet from the Soviet Union. It is clearly doped with Erbium, and like our modern pure Er:

It also as a spray of glittery bubbles which look like stars in its depths

YAG (yttrium aluminum garnet) doped with both cerium and neodymium

Some also have a noticeable afterglow/phosphorescence

This garnet is grown for its incredible green fluorescence which is used in detecting invisible radiation

these will have flaws like minor cracks and inclusions

with a nice greenish/purple hue under fluorescent lamps

some are a little tinted

These could be used to store your most precious items

The only limiting factor is its rarity which has kept it more obscure than gems like ruby and sapphire

'Phantom YAG':  An unusual material that occurs from contamination at the edges of HDSM boules of laser YAG

Christmas garnet is one of our top materials

Production is fairly scarce today and often what we can get is of very low quality
