For that reason it’s important to know what to look for in the small percentage of the worst types of inclusions diamonds can have.

Diamond Inclusion Types to Avoid

In this article we’ll dive deeper into which inclusion types are best to avoid and how to recognize them quickly. 

  1. Black Carbon Spots: not only will they lower the diamond’s ability to sparkle and dampen its brilliance, but they will actually make the diamond look terrible with black little dots inside it, similar to black pepper.

    The diamond’s brilliance and sparkle comes from the light’s ability to reflect, refract and disperse in its external and internal facets; think of it as the light dancing.

    With these black spots inside, the light is absorbed by them blocking its ability to “dance” or create that wonderful sparkles that diamonds are well known and adored for.

    The way to avoid these issues, if you decide to purchase a diamond with black spots, is to make sure the spots are not located anywhere visible, like on the outer lower parts that are usually concealed by the ring setting.

    These diamonds are less expensive, but still you’d want to get the most value for your money.

  2. Center-Stage Inclusions: these inclusions are blatantly located at the center of the diamond, either on its table (flat top part) or inside of it in the middle.

    They are called “Center-Stage” as they seem to be mocking the viewer, distracting and covering the diamond’s potential beauty.

    When looking at a diamond make sure to check its certificate details which usually indicate the location of its inclusions, usually including a magnified image of the diamond.

    But in case that these are not available ask to use a magnifying tool to look at a diamond yourself and make sure there are no show-stoppers like these pesky Center-Stage Inclusions.

  3. Fractures and Cracks: these faults don’t only lower the sparkle of the diamond, they also weaken the integrity of the diamond and lower it’s durability.

    Try to imagine this situation; you purchased a diamond with a small fracture that runs through it top to bottom.

    Everything is fine until one day when you watch your favorite sports team in a high stakes championship match, the best player on your team just missed an important opportunity to score against the opposing team, and they missed by only a few inches.

    You raise your hands in horror, and your ring struck a hard surface causing your diamond to crack in half!! The day just got a lot worse…

    Avoiding these types of diamonds, with a crack or fracture, is a sure way not to be in such a situation in the first place, especially if you can actually see a crack or a fracture reaching the surface of the diamond.

  4. Surface Chips: not only will this lower the sparkle and brilliance of your diamond by not allowing more light to enter or exit the diamond properly, it also means that the diamond’s surface is weaker and prone to even more chips.

    Chances are if you strike the diamond on a hard surface it will chip again.

    The best course of action when you see a chip on a diamond is to avoid it.
