The normal test is to 'beep' it with a thermal diamond tester. This device measures how fast the material conducts heat and can thus tell if it is real diamond or not (diamond is the best heat conducting material at room temperature).
Basically every jewelry store has one of these, so you can ask them to test it for you.
Physically, if the stone appears to be clear, even though it's coloured -- and it is extremely hard, it's worth taking it in for testing. See below for photos of raw diamonds.

Your question is about a raw diamond. A raw diamond must be evaluated for its natural colour and clarity.

Typically more than 50% of the carat weight of a raw diamond is lost during the cutting process.
