4. What are the different lights used for? The short version…

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.

3. How do the buttons work?

The button closest to the USB port is the UV side of the light.

With the first click of that button closest to the USB port will cycle through the UV Spectrums in the following order,

UV365 , UV395 and the intense Blue light.

With each push of the button the you will cycle through the spectrums. 1st click UV365 Mid Wave 2nd click UV395 Longwave 3rd click Blue inspection light 4th click OFF.

Then cycling from there.

The other button controls work the same way, cycling through 2 intensities each of: 1st click bright daylight. 2nd click dimmed daylight 3rd click bright incandescent light. 4th click dimmed incandescent light. 5th click bright infrared light. 6th click dimmed infrared light.

Now with SMART features on the natural light side, hold the button down until it flashes, about 3 seconds, and the next click is OFF.

Or if you’ve left it on one spectrum for more than 10 seconds the next click will be OFF as well.

2. How do I use the condenser cones?

You can use the included condenser cones to focus the light to a sharp point when you are closely examining a stone. They snap right in place on the end of the torch. The rubber grommet keeps them in place while you use them. Store them in the box when not in use to help keep track of them.

1. When/how to charge GemOLight?

A red light will illuminate under the buttons themselves, indicating time for a charge. Any standard mini USB like the one included, when oriented properly plugs right into the USB port next to the buttons. When the red light turns green it is fully charged.

Our lights have been tested to be fully charged and discharged over 1200 times, so if you charge it once every 3 days it should last 10 years or more.
