Have you looked closely at it irl? I suspect it's but a standard guitar-amplifier type, acrylic lens and so.
I've been on the continuous lookout for real-glass, good-looking jewel lights for more than a decade now. I still only find small batches of very NOS "RAFI" brand telephone-exchange-type indicator lights, there's almost nothing else out there matching the criteria. I'm using these for my commercial products, would be nice to have a real viable and modern alternative.
So let us know if you find real-good-versions!
