So let's dive in and see what a real Diamond Plot looks like to understand more.
Keep in mind that the only time you'll ever see an actual plot of a Diamond is if you buy a Certified Diamond that has the Plot drawn right on the Report. (And the Report will actually show 2 Plots! One with a Top-Down view like the one show below, and another from the Bottom-Up View - where the Culet faces towards you!)
Some Certificates (Called Dossier) are smaller and don't show you the Plot of a Diamond. These smaller Certificates will only have the details listed and won't show you where the Inclusions lay. But at least all of the Dossier Reports will be Laser-Inscribed Diamonds, so that's a huge perk!
A Diamond Plot

In this diagram you can see a bunch of marks like Feathers, Crystals, Clouds and Needles. But a Plot will also show things like: Pin Points,
Cracks, Breaks, Fractures, Cleavage Lines,
Bearding, Growth Lines, Grain Lines, Cavities, Knots, Scratches, Nicks, Pits, Abrasions,
Extra Facets, Naturals, and
Trigons! Whew!
Now we learn the really cool stuff... What to do with it! Read on...
