F-35 Fighter Jet Window Sapphire EOTS Cut Loose Gems (F35 Gem)

F-35 Fighter Jet Window Sapphire EOTS Cut Loose Gems (F35 Gem)These are lab created sapphires which were grown for use as a sensor window in the F35 fighter jet but didn't meet spec. They've been faceted in my custom EOTS design which mimics the shape of the sensor array they would have been a part of if they made spec! These stones glow blue under shortwave UV because of titanium contamination. This is a really cool material lab sapphire grown for windows on the F35! These aren't used on the cockpit but on a

but once CZ hit the scene and got insanely cheap the demand for other gem crystals plummeted

Even pinching the stone too hard when bending the silver prongs can make it decide to start cleaving (as we learned to our dismay)

Normally lithium tantalate is colorless but this is a special formula with added magnesium which is used for wafers--the magnesium makes it tougher in addition to giving it this rich yellow-orange coloration

We recently got our hands on a few alexandrite crystal heads

The papers always have justifications about it being a good crystal matrix to hold chromium--but I suspect it has more to do with scientists proving that they can

It has a nylon thumb screw which acts as an adjustable friction brake for vertical operation

as well as for some specimens that show very strong fluorescence (hence why the pheonomenon was named after the mineral)

Inspired by classic videogames

when doped with praseodymium instead you get this very odd multifluorescence: longwave UV gives a pale green

It still looks neat

The crystal structure has been improved over the older versions

but with an even richer and slightly bluer green base
