Diamond Flaws

Exterior Flaws


These diamond flaws are present at the surface of a stone and might arise certainly. However, those are much more likely to be induced due to the outside surroundings, when a diamond was being reduce and polished. These blemishes are classified as beneath. 鑽石耳環


These are pleasant lines determined at the floor of the diamond. They may additionally had been gift obviously or brought on while a diamond changed into cut. While minor scratches can be eliminated through proper sprucing, deep scratches want to be cautiously considered while buying a stone.

Extra sides

These are usually reduce to eliminate blemishes or certain close to floor inclusions on diamonds. At times those greater facets also are reduce to enhance the brilliance of the diamond. These do now not typically have an effect on the readability grade of a diamond.


A breakage in diamonds that isn’t always parallel to the cleavage plane is referred to as a fracture. Fractures are normally abnormal in shape creating a diamond look chipped. The exercise of fracture filling is generally employed to enhance the clarity of such diamonds.


Fingerprint inclusions within the shape of fingerprints can occasionally be determined in diamonds. However such inclusions are uncommon in diamonds in comparison to other stones like rubies. Such inclusions are typically shaped at some point of fluid assisted partial recuperation of fractures already present in stones. For this to take vicinity in diamonds, excessive pressures and temperatures are required, that is uncommon. Till now few such inclusions have been pronounced in herbal blue and colorless diamonds. While this can imply that diamonds had been HPHT handled , giving the specified temperatures for fingerprint inclusions, such isn’t constantly the case. The earth may also motive geologically high temperatures, main to the formation of fingerprint inclusions.


Small holes can be present on the floor of a diamond. These pits are generally no longer seen to the naked eye. However, pits gift at the table aspect of a diamond are typically seen and decrease the clarity of a diamond.


Diamonds are also chipped at locations inflicting the appearance of nicks. This is regularly repaired by using including extra facets. However too many sides lessen the brilliance of a diamond and are to be avoided.


This refers to the unique surface of the diamond which has now not been polished and left as it’s far. Naturals are typically left on or close to the girdle of the diamond. While these are taken into consideration as blemishes, the presence of naturals is an indication of excellent cutting practice, in which the cutter has controlled to maintain as much of the unique weight as possible. Indented naturals also are visible to exist on a few stones, wherein the portion of the herbal is visible to dip internal slightly from the diameter of the stone. Here the cutter normally leaves the indented natural both on the girdle or pavilion of the stone, if you want to hold it less substantive. In such positions, the natural isn’t always seen even with a loupe. Indents can be removed if the cutter polishes out rougher. However, this would result in a drop of the diamond’s weight with the aid of up to twenty-five%.


Diamonds are made from carbon, usually graphite. Nevertheless, even as a diamond is being shaped, it could no longer completely crystallize main to the presence of small dots of black carbon. These black spots had been labeled to be those of graphite, pyrrhotite and pentlandite. These surface flaws resemble a small black dot and can have an effect on the readability of the stone relying on the size of imperfection. The prevalence of this type of flaw is uncommon in diamonds as compared to pinpoint inclusions. Carbons are usually seen in white or blue-white stones. However carbons are not typically observed in diamonds of poorer colours.


The breaking off of a small piece of diamond towards the surface is typically called chipping. The term may be burdened with ‘diamond chips’ which talk over with very small portions of diamonds. These are generally brought about because of minor effect from the environment. Downward effect prompted when a stone is being set or is being worn, can motive chips at the culet of the diamond. As those are usually induced when a diamond is worn, it’s far recommended that at the same time as diamonds are being set, a bit area be left among the base of the diamond and the head of the prongs of the hoop. This space acts as a cushion shielding the diamond from possible chipping when it falls. Chips are however clean to dispose of.


Larger chipping in diamonds leads to a diamond cavity. This term therefore refers to the presence of a large or deep beginning in a diamond. These can be induced either by chance or while a diamond cutter has eliminated a massive crystal inclusion near the diamond floor.

Internal flaws

Crystal/ mineral inclusions

Some diamonds show the presence of small crystals, minerals or other diamonds. These are categorized in diverse classes relying upon the dimensions and shape of the inclusion. While many such inclusions are small in length and not visible to the bare eye, some diamonds might also have large inclusions, which may be seen with the bare eye and can have an effect on a diamond’s clarity and additionally its life. Some crystals resemble a diamond inner a diamond and might also upload to the appearance of the stone. These tackle shapes of bubbles, needles or grains and are categorized as below

Pinpoint inclusions

As the name implies, these inclusions are minute crystals usually white in coloration gift inside the diamond. These resemble a small factor of light and are, through far, the most not unusual of all flaws found in diamonds. Most pinpoint inclusions do not affect the clarity of a diamond and are not seen to the naked eye and are typically now not indicated at the plotting diagrams of diamond reviews. Comments which includes pinpoints now not shown may be listed inside the remarks phase.


Diamond crystals in a diamond can also be present inside the form of lengthy and thin needles. These won’t be seen to the naked eye, unless the needle inclusion is of a substantive color or has a major presence. Some needle inclusions are acknowledged to give diamonds a special appearance too.


The presence of three or extra pinpoint inclusions near collectively can create an area of haze or a cloud inside the diamond. While the incidence of a small cloud is not seen to the bare eye, presence of many pinpoints masking a massive location can affect the clarity of the diamond. These are typically indicated on grading reports in the form of tiny crimson dots close collectively or as circles and different formations.


When diamond crystals increase to the surface of the diamond, they’re called knots. These may be considered underneath right lights situations with a diamond loupe. Certain knot formations may purpose raised areas on specific aspects of the diamond. The presence of knots might also have an effect on both the clarity and sturdiness of the diamond and are pleasant avoided.

Grain traces

Crystal inclusions in diamonds can also arise in the shape of lines, known as grain strains. These are commonly shaped due to improper crystallization of the diamond, whilst it turned into being fashioned. Grain strains can also be brought about because of wrong sprucing of the diamond. Even professional diamond cutters can also come upon diamonds with variations in hardness while a aspect is polished. This can reason microscopic traces throughout the facet. These grains are normally difficult to dispose of with out immoderate weight reduction. Grain strains are usually seen in red fancy diamonds. A saturation of grain lines on pink stones can also lead them to appearance red.


These are cracks inside the stone that resemble the layout of feathers. Presence of this in a diamond normally does no longer affect the existence of the stone unless and till the feather runs via a main length of the stone or suggests primary stress points where it can smash. If the cracks attain the surface or have deep fissures, the sturdiness of the stone may be decreased with the opportunity of the stone breaking with age.

Twinning Wisps

Twinning wisps or intergrowths may also be seen in diamonds. These formations are generally inclusions in diamonds that have twisted collectively at some stage in the time of diamond formation. Thus various inclusions like pinpoints, needles or feathers might also shape together growing a white strip within the diamond. Surface graining can also be seen in some instances. Such intergrowths are more normally seen in fancy shaped diamonds and are extremely uncommon in ideal reduce diamonds.


These are cracks in a diamond that occur in a directly line and are parallel to one of the diamond’s crystallographic planes. Cleavages are normally resulting from deep internal pressure in a diamond and could also were resulting from a robust blow on the diamond. It commonly indicates no feathers and has a remarkable threat of causing the stone to break up, specifically if positioned inside the high strain grip of prongs in rings. Stones with cleavage must be selected cautiously and avoided as a ways as possible.


Also referred to as girdle fencing or ‘dig marks’, this is prompted across the diamond’s girdle as the diamond is cut or bruited. These nice strains typically resemble a hair strand and do no longer gift a problem. However sizeable bearding can lessen the brightness of the diamond. It is appropriate that such diamonds be cut or polished again to enhance luster.

Diamond flaws aren’t constantly a negative phrase. In reality it’s miles these flaws that regularly lend a loose diamond its exclusive splendor. It is frequently these flaws that make a stone look precise and often enhance its value lots similarly. It is but necessary that while buying individual diamonds, the customer examines them with a jeweler’s magnifier to check its brilliance and the presence of flaws. Careful issues will move a protracted way in helping you purchase a stone that stays precious, lovely and unique for a lifetime.
