Let's continue with number 2...
2) Inclusions Top and Center
If you have an Inclusion dead center of your Diamond, it will not only look bad, it'll drive you crazy.
You'll always be staring at it. It'll overpower your Diamond. You won't be able to look at anything else but that spot! No amount of Brilliance or Sparkle can hide it. It's right on the top, floating in plain view like a scar.
You'll find yourself constantly trying to rub it or wipe it away. It won't help! Once you know it's there, you'll be blinded by it. Eye-visible Inclusions stop light and make your Diamond look dirty. You won't want to show it off to anyone for fear that they'll see that bulls-eye Imperfection. Eye-visible Inclusions like this are considered an I Clarity Diamond!
Try to skip Inclusions that reside top center of your Diamond. Get Inclusions that lay deeper into the Diamond, or off to the side of the stone, where it's hidden by the facets. Never directly in the center!
3) Long Cracks or Fractures
Cracks, Fractures, Lines and Flaws not only look horrible, but they weaken your Diamond. If you hit your Diamond hard enough, your Diamond could literally break in half. It will crack right where the fault line is! Your Diamond will now be split into two chunks of worthless rock!
Fractures and Cracks are sightly, deep and long. They block light, look dark, and cloud up your pretty little Diamond. All it does it leave your stone vulnerable.
Be careful about purchasing a Diamond with long cracks and lines in them. It may be cheaper than other Diamonds, but a broken stone is impossible to fix!
Don't waste your money. Skip the crack!
4) Chips on the Side of the Diamond
The last of the worst types of Inclusions to have in a Diamond are the ones that Chip or Break the surface of your Diamond.
(As a side note: A Chipped Diamond can also mean that the Diamond's Girdle is thin and fractures easily.) (Read more about The Diamond Girdle!)
