specifically, are there colourations within the surface geology that increase the probability of possible diamond sites beneath?

The diamond "pipes" are ancient volcanic vents raching to great depths. Kinberlite is a type of magma formed at those depths. However, by no means all kimberlite pipes have diamonds in them.
Also, while diamonds originate in kimberlite, they aren't all found there by any means: the pipes erode, the diamonds get washed out, and they accumulate in sediment deposits. All the commercial diamond working in Namibia are of this type. So you look for sediment patterns, try to workout where the flow has come from, and see what is in the source area.

Putting it simply there needs to be traces of diamonds themselves to be found. It's most likely to be glass like structure and very hard in nature. It would be very difficult to brake or drill into. When light shines into it, you may see the colours of the rainbow.

They are found in things called kimberlite pipes, a ~circular on surface, tubular area in (usually) very old bedrock. The rock type is very ultramafic extrusive volcanic rock, called komatiite or kimberlite, which is very rare. In canada, they are usually found by doing geophysical surveys- the komatiite is very weak, and it weathers to clay and breaks down. So, they look for low gravity and circular depressions.

Dont be silly ...its a sign with a little arrow pointing and saying diamonds

I find my diamond mines at the mall!
