Exterior Flaws


These diamond flaws are gift at the surface of a stone and can occur naturally. However, those are much more likely to be caused because of the outside environment, when a diamond become being cut and polished. These blemishes are labeled as below.


These are fine strains determined on the floor of the vvs diamond. They might also were present clearly or brought about when a diamond changed into cut. While minor scratches can be removed via right polishing, deep scratches need to be cautiously considered whilst shopping a stone.

Extra aspects

These are commonly reduce to put off blemishes or certain close to surface inclusions on diamonds. At times those extra facets also are cut to beautify the brilliance of the diamond. These do not generally affect the clarity grade of a diamond.


A breakage in diamonds that is not parallel to the cleavage aircraft is called a fracture. Fractures are commonly abnormal in shape creating a diamond look chipped. The exercise of fracture filling is commonly hired to improve the clarity of such diamonds.


Fingerprint inclusions within the form of fingerprints can on occasion be determined in diamonds. However such inclusions are uncommon in diamonds as compared to different stones like rubies. Such inclusions are usually formed during fluid assisted partial healing of fractures already found in stones. For this to take vicinity in diamonds, excessive pressures and temperatures are required, that is unusual. Till now few such inclusions had been stated in natural blue and colorless diamonds. While this can indicate that diamonds had been HPHT handled , giving the specified temperatures for fingerprint inclusions, such isn’t always always the case. The earth might also motive geologically excessive temperatures, leading to the formation of fingerprint inclusions.


Small holes may be gift on the surface of a diamond. These pits are usually no longer seen to the bare eye. However, pits gift at the table side of a diamond are generally visible and decrease the clarity of a diamond.


Diamonds are also chipped at places inflicting the appearance of nicks. This is frequently repaired via adding extra sides. However too many sides lessen the brilliance of a diamond and are to be averted.


This refers to the unique surface of the diamond which has now not been polished and left as it’s miles. Naturals are commonly left on or near the girdle of the diamond. While these are considered as blemishes, the presence of naturals is an indication of precise slicing practice, in which the cutter has managed to keep as tons of the original weight as feasible. Indented naturals also are seen to exist on some stones, wherein the portion of the natural is visible to dip inside slightly from the diameter of the stone. Here the cutter commonly leaves the indented natural either on the girdle or pavilion of the stone, for you to preserve it less significant. In such positions, the herbal is not seen regardless of a loupe. Indents can be removed if the cutter polishes out rougher. However, this would bring about a drop of the diamond’s weight by using up to 25%.


Diamonds are made from carbon, commonly graphite. Nevertheless, while a diamond is being shaped, it could now not completely crystallize main to the presence of small dots of black carbon. These black spots have been labeled to be those of graphite, pyrrhotite and pentlandite. These floor flaws resemble a small black dot and may have an effect on the clarity of the stone depending on the dimensions of imperfection. The incidence of this form of flaw is uncommon in diamonds as compared to pinpoint inclusions. Carbons are commonly seen in white or blue-white stones. However carbons are not generally determined in diamonds of poorer hues.


The breaking off of a small piece of diamond closer to the surface is commonly referred to as chipping. The term may be confused with ‘diamond chips’ which seek advice from very small pieces of diamonds. These are usually caused because of minor effect from the surroundings. Downward effect precipitated while a stone is being set or is being worn, can purpose chips at the culet of the diamond. As those are usually brought on whilst a diamond is worn, it’s miles counseled that even as diamonds are being set, a bit space be left between the bottom of the diamond and the top of the prongs of the hoop. This area acts as a cushion defensive the diamond from viable chipping whilst it falls. Chips are however clean to get rid of.


Larger chipping in diamonds ends in a diamond cavity. This term for this reason refers to the presence of a large or deep starting in a diamond. These can be precipitated either by chance or whilst a diamond cutter has eliminated a massive crystal inclusion close to the diamond surface.

Internal flaws

Crystal/ mineral inclusions

Some diamonds show the presence of small crystals, minerals or different diamonds. These are classified in diverse classes relying upon the scale and structure of the inclusion. While many such inclusions are small in size and now not seen to the bare eye, a few diamonds may additionally have massive inclusions, which may be visible with the bare eye and might affect a diamond’s readability and also its lifestyles. Some crystals resemble a diamond internal a diamond and might also upload to the look of the stone. These take on shapes of bubbles, needles or grains and are classified as below

Pinpoint inclusions

As the name implies, these inclusions are minute crystals usually white in colour gift in the diamond. These resemble a small point of mild and are, by using a ways, the most not unusual of all flaws observed in diamonds. Most pinpoint inclusions do not affect the readability of a diamond and aren’t seen to the naked eye and are generally no longer indicated at the plotting diagrams of diamond reports. Comments together with pinpoints now not shown can be indexed within the feedback phase.


Diamond crystals in a diamond can also be present within the shape of lengthy and thin needles. These may not be visible to the naked eye, unless the needle inclusion is of a sizeable colour or has a sizeable presence. Some needle inclusions are acknowledged to give diamonds a special look too.


The presence of three or greater pinpoint inclusions near collectively can create a place of haze or a cloud inside the diamond. While the incidence of a small cloud isn’t always seen to the naked eye, presence of many pinpoints overlaying a large location can affect the readability of the diamond. These are typically indicated on grading reviews in the form of tiny crimson dots close collectively or as circles and other formations.


When diamond crystals extend to the floor of the diamond, they may be known as knots. These may be regarded underneath proper lights situations with a diamond loupe. Certain knot formations may additionally purpose raised regions on specific aspects of the diamond. The presence of knots may affect each the readability and sturdiness of the diamond and are high-quality averted.

Grain traces

Crystal inclusions in diamonds also can arise inside the shape of traces, known as grain traces. These are normally fashioned due to improper crystallization of the diamond, while it become being formed. Grain strains can also be caused due to flawed sprucing of the diamond. Even skilled diamond cutters may also stumble upon diamonds with variations in hardness when a side is polished. This can cause microscopic lines throughout the aspect. These grains are typically hard to get rid of without excessive weight loss. Grain lines are normally visible in red fancy diamonds. A saturation of grain strains on red stones also can cause them to appearance purple.


These are cracks within the stone that resemble the design of feathers. Presence of this in a diamond usually does no longer have an effect on the life of the stone unless and until the feather runs through a major length of the stone or shows most important strain factors where it can spoil. If the cracks reach the surface or have deep fissures, the sturdiness of the stone may be reduced with the opportunity of the stone breaking with age.

Twinning Wisps

Twinning wisps or intergrowths can also be visible in diamonds. These formations are commonly inclusions in diamonds that have twisted together at some stage in the time of diamond formation. Thus various inclusions like pinpoints, needles or feathers might also shape collectively developing a white strip within the diamond. Surface graining will also be seen in some cases. Such intergrowths are greater typically visible in fancy fashioned diamonds and are extremely uncommon in perfect reduce diamonds.


These are cracks in a diamond that occur in a immediately line and are parallel to one of the diamond’s crystallographic planes. Cleavages are commonly resulting from deep inner stress in a diamond and can also had been because of a robust blow on the diamond. It typically indicates no feathers and has a exquisite risk of inflicting the stone to break up, mainly if located inside the high stress grip of prongs in rings. Stones with cleavage must be selected carefully and averted as a long way as possible.


Also known as girdle fencing or ‘dig marks’, that is brought about around the diamond’s girdle because the diamond is cut or bruited. These exceptional strains generally resemble a hair strand and do now not gift a problem. However widespread bearding can lessen the brightness of the diamond. It is appropriate that such diamonds be reduce or polished again to enhance luster.

Diamond flaws aren’t always a poor phrase. In truth it is these flaws that often lend a unfastened diamond its extraordinary splendor. It is frequently these flaws that make a stone look unique and regularly improve its value much in addition. It is however essential that even as purchasing man or woman diamonds, the customer examines them with a jeweler’s magnifier to test its brilliance and the presence of flaws.
