Hi, Leeuwenstein - I recommend you don't yet use the mobile spectrometer (which is experimental) but the desktop version:

Once you have built it, you can follow instructions here:

They are a little out of date but will be updated soon and mostly work fine. Calibration info is here:

Good luck, spectrally analyzing gemstones sounds very interesting. You might try using an ultraviolet light.

In general, you'll find a lot of info and data on:
