Which diamond inclusions are the worst?

Diamond inclusions, or internal characteristics that extend into the diamond from the surface, include bearded girdle, bruising, cavity, chip, cloud, crystal, feather, grain centre, indented natural, internal graining, internal laser drilling, knot, laser drill hole, needle, pinpoint, and twinning wisp. These flaws might be minor or severe, depending on how well the stone transmits light. Let’s see which diamond inclusions are the worst and why we should avoid them.

Diamond inclusion to avoid

1. Cavity

A tiny, somewhat deep angular aperture known as a cavity is formed when a crystal is removed or dropped during the polishing process. In other words, a hollow in a diamond can be thought of as a surface hole. Polishing can remove cavities, but a cutter must recut the diamond to completely remove a cavity inclusion from its surface, reducing the diamond’s weight.

As a result, cutters prefer to preserve a higher weight even if it means sacrificing some clarity. As dirt and oil accumulate on these inclusions, they darken and become more obvious over time. The hollow can represent a danger to the stone’s durability. Thus, it’s best to avoid such stones.

2. Dark Crystal

Crystals are formed by uncooked diamonds and other minerals contained in a stone. Crystals are often colourless or white, depending on the mineral present. Crystallized carbon patches might look like dark crystals or as little black spots. Too many huge black specks will detract from the stone’s aesthetic charm. The presence of black spots, which are only visible to the naked eye, does not affect the diamond structure. Black crystals in gemstones should be avoided in general because they can diminish the fire, brilliance, and scintillation of the stone by blocking light from entering the stone. When choosing between two diamonds with poor clarity and black spots, a stone with black spots on the sides or deep within the stone can be a suitable choice.

3. Long feathers

A feather is an inner fracture in a diamond. Depending on the angle of observation, a feather can appear virtually unnoticeable or as a tiny white diamond. There are gray and brown feathers visible to the naked eye. Long feathers may present durability issues, particularly if they reach the surface of the girdle. Long

feathers increase a diamond’s susceptibility to stress, and a strong hit can result in fractures. Large diamonds that are shattered are often of inferior quality and cost less. Paying less for a stone is not worth the risk of receiving a flawed one.

4. Chips

It is a small, shallow opening on the diamond’s surface that is most common at the culet, girdle edge, or facet junction. Accidental damage or normal wear and tear are the most common causes. More than only chips can be seen with the naked eye; they’re a bigger concern than first appears. There is a larger risk of the chip growing and spreading if the stone’s structural integrity has been affected. It should go without saying that a diamond with chips will be provided at a discount as the stone’s value has been diminished.

Lab-grown diamonds

A diamond produced in a laboratory is known as a lab-grown diamond. Rare Carat is the best place to find lab-grown diamonds. Scientists can now produce diamonds that optically resemble diamonds mined from the earth, have the same chemical and physical properties, and are accredited using the popular techniques of Chemical Vapor Deposition or High-Pressure High Temperature found at www.rarecarat.com.

Are lab diamonds real?

Yes. Diamonds grown in a lab are just as real as diamonds dug up from the ground. Like real diamonds, they have shape, size, colour, and clarity grades. Both real diamonds and diamonds made in a lab are certified and have the same physical and chemical properties.

How lab diamonds are made

Lab diamonds have two ways of manufacturing listed below;

1. High-pressure high temperature

High-Pressure High-Temperature (HPHT) is the second approach (HPHT). This is meant to resemble the creation of genuine diamonds in their natural environment. Natural graphite is crushed under high pressure and heat in a large machine during this process. Graphite turns into diamond under these conditions.

2. Chemical Vapor Deposition

Chemical Vapor Deposition is the first step in the process (CVD). A seed crystal, a tiny diamond seed, is placed in a small chamber. Filling the compartment with hot gases follows. As soon as the gas temperature reaches a certain level, the seed crystal begins to sprout carbon layers. Because of this, the seed grows into a square-shaped diamond crystal.


Diamond inclusions, or internal characteristics that extend from the surface into the diamond, including the following: bearded girdle, bruising, cavity, chip, cloud, crystal, feather, grain center, indented natural, internal graining, internal laser drilling, knot, laser drill hole, needle, and A lab-grown diamond is created in a laboratory. Scientists can now create diamonds that look like natural diamonds and have the same chemical and physical qualities.
