Does this work on natural gemstones?

Yes, it works on both artificial gemstones and natural gemstones.

Does it come with instructions for testing turquoise, rubies and saphires?

Hello - This device can only detect authentic diamonds (loud beep, beep, beep) or metals (fast buzzing beeps). Keep in mind that you MUST allow the "lamp" to power up and you MUST be holding the item with your fingers. This device will not determine genuine gemstones (i.e. rubies or sapphires) nor distinctions in metals (i.e. gold, silver or steel). So it will not determine if rubies, sapphires or turquoise are real. The only true way to do that is through a reputable jeweler. They have devices (light refractors) and experience to make those determinations but it may cost you for them to provide that information. I hope this helps.

I only tests diamonds, it was misleading in the description

What is the difference between the black and multicolored tool?

The difference would be what the tool is capable of measuring. It measures the hardness of the stone. If a real diamond, it will light up and beep. Precious stone light it up in the mid area range.
