When people are shopping for Loose Diamonds, they're always curious about
Clarity and Inclusions. They always want to know what types of Inclusions are
the Worst Inclusions to have in a Diamond.
Is it Imperfections like: Fractures, Chips, Bearded Girdles, Extra Facets, Naturals, or Scratches?
Or is it Inclusions like: Black Carbon Spots, White Spots, Clouds, Pinpoints, Crystals, or Feathers?
Some Inclusions are okay to have, some are on the bottom of the list. Let's take a look...
The 4 Worst Inclusions
Out of all the Inclusions and Imperfections that you could have, there are a couple of different types of Inclusions that are considered really bad. Most honest Jewelers will try to steer you away from these types of Inclusions. They are...
1) Black Carbon Spots.
2) Inclusions, Top, Center of your Diamond.
3) Cracks or Fractures running through your Diamond.
4) Chips or Cracks on the side of the Diamond.

1) Black Carbon Spots
Black Carbon Spots are Dark or Black Inclusions that look like pieces of Pepper. (Read: Black Pepper in your Diamond!) They are very noticeable in Diamonds and stand out like a sore thumb.
Black Carbon Spots are normally only visible in Diamonds with I1, I2, and I3 Clarity. (Sometimes you can see Black Spots in SI2 Clarity Diamonds, only visible from the side view though!)
Black Spots in your Diamond are actually Pure Carbon Minerals that never crystallized properly. Black Spots also identify it as a low grade Diamond. If you have Black Spots in your Diamond they will be in there forever.
Not all Carbon is Bad...
The more preferred Carbon Inclusions to have are White Carbon Spots!
White Inclusions can be the same size and shape as the Black ones, but because they're White, it makes it harder to see them. A White Diamond masks the White Imperfections. So if you must get inclusions, get the White ones! Read more: White vs Black Inclusions!
Point is, stay away from Black Spots!
No Bride-to-be will want to stare at an Ugly Dark Flaw for the rest of her life!
