Daylight- a wavelength that closely mimics sunlight so you can see what stones may look like in natural light.
Incandescent- many stones such as alexandrite and some garnets and sapphires will exhibit a distinct color change in a typical incandescent light given off by a tungsten filiament. This wavelength closely mimics that of the traditional bulb or even the light of a flame, such as a candle.
Infrared light- has many applications which are being explored as we speak…stay tuned.
Longwave (A) UV 395 nm
Longwave(A1) UV 365 nm
Blue Amber Inspection light, as of now, I cannot pinpoint the exact spectrum.
I have personally used it to differentiate between natural and artificial amber and I’ve used it to examine jade, in which applications the light penetrates so strongly that you can have good idea of what resides inside of the stone, at the same time the light being blue it seems to not wash out the colors and inclusions making them easier to see.
Also, another feature I have never seen before it causes certain fluorescent reactions in some stones, such as a calcite clam from Florida glowing bright red.
