Kunzite gemstones can be identified as true or false based on their colour. The colour of a genuine gemstone is either very pink or pinkish violet. Most kunzite stone cutters will shape the stone's face such that the angle at the top emphasises the stone's richest, brightest pink. When you hold the stone in your hand and look at it from various angles, you'll see that it has a variety of colours, which distinguishes it as a real gemstone.
