Diamond inclusion is the error of the crafting process during the polish on the grading wheel. Inclusions in diamonds are not placed, but during the process, it’s automatically generated due to more pressure and heat, which isn’t in the control of the diamond polish worker. It’s an exception which diamond manufacturers have to mandatory accept; there isn’t a way to escape.
If the diamond manufacturer wants to take a high price for included diamonds, then it will be a very severe result bring out. This is because diamond inclusions are not the total result of the polishing process, but they sometimes carry natural inclusions which can’t remove from the diamond polishing manufacturing process.
Let’s clarify the diamond inclusions and types to determine why it’s important and affecting for the purchasing decisions.
What is an inclusion in a diamond?
Inclusion in a diamond means some types of errors or signs which affects the clear and transparent appearance. Diamond inclusion is mainly generated in the polishing and crafting process, where the diamond anatomy was shaped in predefined proportions and dimensions. Sometimes more pressure falls on the particular diamond anatomy, such as the table, crown, girdle, and pavilion, and lines or scratches generate those are called diamonds in inclusions.
Diamond inclusion is the type of defect which destroys the glorious look of the diamonds instead of having the best color grade and best diamond cut. There’s no space for the best characteristics of diamonds when having inclusion in the surfaces or maybe on the anatomy.
Diamond inclusion meaning
Diamond inclusion meaning is a structure covered with natural or maybe artificial defects on the anatomies. Diamond inclusion separates the light reflections in various directions, which makes it duller and untransparent depending on the amount. In simple terms, inclusion in a diamond means tells a diamond's internal and external structures have a crack formed appearance.
Buyers have space to understand that diamond inclusions decided the clarity grade of the diamond and, from that overall price acquired. Thus, buyers can also identify diamond inclusions as price decider factors that can help pay the right price.
Diamond inclusions types
Diamond inclusions have 14 types which are decided by the amount and placement of inclusions on the anatomies. Inclusions diamond types are scales on the diamond anatomy placing space which could be better for the appearance. That’s why from the different looks of diamonds(having impurities), inclusions are scaled in varieties known as inclusion charts.
List of diamond inclusions types
- Bearding Inclusion of Diamond

- Diamond Chip Inclusion
- Diamond Cloud Inclusion
- Crystal Inclusion in Diamond
- Diamond Feather Inclusion
- Graining Diamond Inclusion (known as internal graining diamond)
- Intended Natural Diamond Inclusion
- Knot Inclusion In Diamond
- Needle Inclusion in Diamond

- Twinning Wisp in Diamond
- Internal laser drilling diamond (type of diamond inclusion)
- Laser drill hole diamond
We can one by one see the diamond inclusions types. So, you can be aware of the inclusion of diamonds and able to decide to purchase diamonds.
A. Bearding inclusion of the diamond
This bearing inclusion of diamond looks like a hair of beared, which counts in a group and is found around the girdle anatomy. Bearding inclusion type of diamond will take birth during the polishing process of the girdle anatomy because sometimes more pressure becomes a cause to generate it.
Where is the Bearding inclusion diamond type found?
Bearding types of diamond inclusion found around the girdle anatomy corners with the 360-angle covered-up format. The girdle of a diamond is covered with the bearding inclusion types, which is easily noticeable in the 10x magnifications. Bearing diamond inclusions type doesn’t affect the sparkle for more, but yes, the small amount of reflection stops there.
B. Cavity in Diamond (type of diamond inclusions)
The cavity in a diamond means that one part or facet of the girdle is a miss or loss during the inexperienced polishing and manufacturing process. Diamond cavity suggests that a diamond girdle since now the lost sparkling reflection ability and can’t able to provide an optimum look. Usually, the diamond cavity type of inclusion is identified when a one-triangle faceting is not available on the anatomies of the girdle.
Diamond cavity structure is mismatched during the crafting process of symmetry. Because when crafting workers want to place a diamond symmetry on the girdle, then more pressure not absorbs by the anatomy. As a result, for one side, more pressure came as the loss of that part of the diamond, which is the Cavity Diamond Inclusion Type.
Diamond cavity inclusions are generally found near the crown corner, which connects to the girdle anatomy.

C. Diamond Chip Inclusion
A Diamond chip inclusion means that a diamond anatomies carries a miss part or space between each other aspects, such as a diamond crown doesn’t match with the girdle surfaces. Moreover, a chip inclusion diamond type doesn't succeed in creating a bridge between the characters and has a scratch appearance to stop the reflective ability.
Chip diamond inclusions are found near the girdle and crown faceting borders with scratchy efficiency to affect the sparkle reflections. Chipped diamonds aren’t worth anymore if they carry more inclusions on the surfaces. But if the amount of inclusions is less, then it will be worth buying chipped diamonds.
D. Cloud Diamond Inclusion
Cloud diamond inclusion indicates that white colored defects are appeared or may be placed during the manufacturing process in the form of tiny dots. In diamond cloud inclusion, the clear sky colored(usually white) structure is created for not approving the light reflection as the cloud stops the ultraviolet rays released from the SUN.
Clouds in diamonds are neither bad nor good, but it depends on which place it appears and which quantity. If clouds in diamond appeared on the table anatomies, then it absolutely decreased the reflections. As a result, cloud in diamonds clarity means that it will attain less graded clarity, known as SI2 or I2 and I3. Because clouds in diamonds can’t be able to throw sparkle reflections.
E. Crystal Inclusion in Diamond
Crystal inclusion in a diamond definition that mirrors typed scratches lines is available in yellow, black, and green color on the diamond anatomy, which can be found without a 10x magnification loup. Instead, crystal inclusion will be found in the microscope machine, where the diamond inspector will understand its characteristics of it for approval.
Crystal diamonds aren’t bad, but it will be appreciated if they can’t be noticed with a clear, opened eye and are not noticeable in the light reflection. Diamond inclusion of crystal type transforms from which type of mineral is used when a crafting process is done. Look, diamond absorbs more heat and temperatures in laboratories and mines then sometimes it can release the sign of defect called diamond crystal inclusion.
In negative crystal inclusion, we can’t tell that it’s a total defect of the polishing process, but diamond often gains a naturally crystal type of inclusion which decreases the overall value. The customer doesn't want to buy a crystal inclusion diamond for having different hues on the pavilion and girdle anatomy(usually crystal inclusion founding place).
Crystal inclusion diamond is decided with the color mineral usage such as reddish(garnet), black(carbon), and greenish(peridot).
Is Inclusion in diamond determining diamond fluorescence grade?
Yes, inclusion in diamond decides diamond fluorescence grade because the sparkle reflection depends on it. Diamond fluorescence is a blue colored light that reflects in a mostly dark atmosphere. That's why if any diamond carries inclusion on the table anatomy or crown anatomy maybe then a diamond fluorescence grade turns from Medium to None.
F. Diamond Feather Inclusion
This inclusion contains a fracture or puncture on the girdle anatomy in the form of a transparent and invisible line to the naked eye. It usually generates in the polishing process where the grading wheel interacts with the girdle placement. Feather inclusion in a diamond means that a girdle surface is covered with different line faceting patterns which not match with the ideal faceting style on diamonds.
Diamond feather inclusions are known as hackles diamonds inclusions due to having a fraction of scratches.
Diamond feather inclusion is a durability risk? Not at all. When a diamond inclusions scale at the feather type that understands it does not decrease the durability; after all, diamond has a form of tough carbon. Feather diamond inclusion means that a bit of part of the anatomy is covered with unmatched faceting patterns, which not look beautiful and optimum, but it decreases the diamond’s overall appearance.
G. Graining in Diamond (diamond inclusion type)
Graining in diamonds means that surfaces are limited to facing more lights and decreasing the reflection amount. Graining diamond inclusion means acknowledging the internal structure is covered with defects and unable to release lights.
Internal graining in diamond is the one type of polishing process during the manufacturing, and sometimes the diamond space(a particular place such as a girdle or maybe a pavilion) cannot catch fire, and that part appears as a crease with milky and faint color.
Internal graining on a diamond shows how beautifully and carefully the faceting work has been done. Because in the diamond’s internal part, placing a faceting pattern isn’t easy anymore; it demands a high level of craftsmanship.
If any tiny mistake occurs during the internal graining diamond process, then it features the inclusions, called as graining diamond inclusions. Diamond manufacturers want to produce something other than graining including diamonds, to avoid less final prices. That’s why it is called as internal graining diamond inclusion.
H. Intended natural diamond inclusions
Intended natural inclusion meaning that a diamond part isn’t polished and is still in the rough stage because it is sometimes essential for the overall appearance. The intended natural meaning is that a specific part of a diamond is not changed during the polish or crafting process.
If that specific part(ordinarily diamond crown and girdle) is polished, the diamond lose the anatomy and manufacturer lose their expected cost or production. Therefore, the intended natural diamond will be easily available at less price that doesn’t have the polish effects on the crown(usually intended natural diamond inclusion found).
Intended natural inclusion isn’t placed or created, but when a diamond is found or grown in the mines and laboratories, some of its parts would be mandatory kept the same or as it is. If the diamond manufacturer wants to remove the diamond's intended natural inclusion, then a diamond loses its value and reflective ability.
Intended Natural vs Chip
Between Intended natural vs chip, intended natural is appreciative because it doesn’t more affect the light reflections, but it isn’t noticeable with opened eye and sometimes does not appear in the 10x magnification. While chip inclusions of diamonds are easily detectable from the girdle anatomy inspections during the polish process. Chip type of diamond inclusion has lost part of the girdle anatomy where they were actually found. Thus, between intended natural vs chip inclusion comparison, intended natural diamonds imperative.
I. Knot Diamond Inclusion
Knot diamond inclusion means that a tie typed group of impurities has appeared on the diamond table and girdle surfaces. This knot in the diamond will not deliver the deserved light reflections but will provide less light in the exit. Knot inclusion diamond has mostly been covered with scratches and defects during the polishing process.
In knot shaped diamond inclusion, the form is round, and it has white color than the actual color grade of diamonds; that’s why knot diamond inclusions are easily identified. In addition, knot diamond inclusions are easily identified for having bigger shapes than chip inclusion diamonds. As a result, knot inclusion diamond sells for less than its actual price.
Can knot diamond inclusion affect the overall clarity grade?
Yes, a knot diamond inclusion affects the overall clarity grade because it comes with group impurities that decrease the diamond's glorious and transparent look. As a result, knot diamond inclusion gained I1, SI2, and I3 clarity grades depending on the number of inclusions.
J. Diamond needle inclusion
Diamond needle inclusion means diamond surfaces covered with scratches look like injection needles with sharp edges. This needle diamond inclusion was found at the crown and pavilion anatomy because the polish process was done many times for exact symmetry.
Needle diamond inclusion isn’t found during the mining or laser process, but it carries the impurities from its original form, which can’t easily to remove, and if it does, the look will be ugly and ordinary. In addition, inclusion as the needle in a diamond will quickly not appear for viewing; it needs the 10x magnification or microscope machine to be identified.
K. Pinpoint inclusions in diamond
A pinpoint inclusion in a diamond means the sparkle affections are severely impacted due to having a block on the diamond anatomy. Thus, pinpoint inclusion diamonds carry impurities on the crown and pavilion surfaces which are the most especial factor of brilliance, fire, and scintillated light response.
In diamond pinpoint inclusion, the girdle and pavilion faceting were overworked with more pressure during the polish process. As a result, 50% of diamonds carry pinpoint inclusions lose their refractive index. That’s why pinpoint inclusions in diamond scales between the clarity grade of VS1 and SI2 depend on the number of inclusions on the anatomy.
L. Twinning wisp inclusion
A twinning wisp of inclusion means that all the impurities are gathered or coupled with each other and placed in the internal & external structures. Because a twinning diamond wisp inclusion tremendously affects the light reflection ability, it scales on VS2 or maybe I3 clarity.
The twinning wisp in a diamond suggests that hard carbon surfaces (a diamond) are covered with different types of inclusions such as cloud, chip, pinpoint, needle, graining, and intended natural. In twinning wisp inclusion diamonds, all the space is covered with many of the impurities, such as I3 or maybe I1 clarity. As a result, twinning diamond wisp inclusion scales between I1 to I3 clarity.
M. Laser drilling inclusion (Known as internal laser drilling)
Internal laser drilling means diamond anatomies are drilled from the heat and lose their stabilized structures. When a laser process starts to give a specific shape to a rough diamond, then sometimes laser rays pressure increases, or maybe the rough diamond doesn’t control the heat of the rays. As a result, the diamond came out as laser drilled, which isn’t valuable anymore, and if it carries values, then it gives only 5-10% of the actual value.
Laser drilled inclusion diamonds can acquire less graded quality, such as I1 to I3, for having more impurity on the pavilion or maybe at the table surfaces. The laser drill will be fallen any of the surfaces of diamonds; it's not predefined and predetermined. It totally depends on the laser machine operator, who knows the diamond characteristics better.
N. Laser drill hole inclusion (Not recommended)
When a diamond has laser drill hole inclusion, then it’s a clear indication that some part of the diamond destroys from the exact place, or maybe it missed the deserved place for absorbing high temperature in the laser machine. Laser drill hole inclusion means that a diamond cannot generate the demanded value and cannot release more lights in return.
Laser drill hole inclusion is the total error of the laser machine operator who fails in handling the temperature and wants to create better diamond internal & external structures. Laser drill hole diamond loses its actual value, or sometimes maybe, at 100% breakage. Laser drill hole diamond inclusion, which means that a diamond has zero value instead of doing all the rough-to-polish diamond process. Diamond manufacturers can’t be able to get revenue from the laser drill hole inclusion diamond.
This is the end of diamond inclusions examples that scale on the amount of impurities which is naturally or artificially available on the anatomy of the diamond. If buyers purchased the diamond having inclusions, isn’t mean that it is not sparkly or good, but it depends on how much the inclusions are available on the diamond surfaces. Thus, these diamond inclusions types do not approve lights to reflect with more ability.
