Of the three major factors for determining the colour of Tourmaline, this is the most significant. It relates to the extent to which the colour is bright/clear.
"The T-Shirt Analogy" is when a T-shirt comes to mind: the kind with the deep, crimson red colour. It starts off as a bright red colour. Over time, it will fade to an inferior state because the colour will wash out of it. When it first came out, it was intensely vibrant, but over the years, the brightness faded.
When evaluating a Tourmaline for colour quality, one must consider the richness and vibrancy of the colour saturation.
Tourmaline has different illumination requirements according to the colour kind. Coloureds, greens, blues, and violets tend to appear the most attractive under daylight lighting, while reds, oranges, and yellows appear best under incandescent lights. Whenever purchasing these semi precious stones, one should examine them under different light sources in order to avoid problems.

Tourmaline's varying grades of clarity tend to come from a single kind. This means that even while the marketplace has some nice big blue and blue-green tourmalines with clarity, practically all tourmalines with a red or pink colouration will have noticeable inclusions. Tourmaline is known for being full of broken crystals and healed liquid-filled cracks. It is not uncommon to see needle inclusions.

As with the colours of tourmaline, the cutting has many variations. To display one of the pleochroic colours, darker tourmalines are chopped to expose the other one. The c-axis should be parallel to the table facet. Because tourmaline crystals are lengthy, tourmaline gems cut in this orientation are commonly rectangles and rectangular emerald cuts. Lighter tourmalines often show richer colour if they are positioned with the table facet at a 90-degree angle to the c-axis. This results in them being chopped into rounds, triangles, trillions, and ovals quite commonly. Take a look at the tourmaline suite and you'll see for yourself. Cabochon cut tourmalines are seen with faceted gems.
