We at Kiran Gems believe in sharing knowledge about diamonds and its necessary attributes that affects its valuation. The knowledge here would serve handy while buying or selling loose diamonds. A diamond’s quality and value is judged on four fundamental characteristics, known as the Four C’s (4Cs). These are the clarity , colour , cut and carat weight of a diamond. The higher a diamond is graded on one or all of these characteristics, the scarcer and more costly the diamond will be. Most of us will choose one or two of these characteristics at a higher grade at the expense of the others. This will reflect a personal preference. Some buyers prefer a large sized diamond and are not too concerned with the clarity. On the other hand some buyers look for a well cut diamond and will be prepared to compromise on size and clarity. We invite you to discover more about diamonds and find out which characteristic is most important to you.
The larger the stone, the more rare and higher the price per carat
The less colour the better. Light refacts more through colourless stones, giving greater rediance.
Light travels better through clean windows. The clearer the stone, the higher the price
The better the cut, the greater the sparkle.Precise angles maximise brilliance and add extra value.

Carat is the unit of measurement used to weigh diamonds. One carat is the equivalent of 200 milligrams, or 0.2 grams. The word carat is derived from carob seeds that owing to their very slight weight-variance, were used to balance scales in ancient times. Due to the processes involved in the formation of nature, large diamonds are created less frequently then smaller sized diamonds. Due to the rarity of larger sized diamonds they command substantially higher prices than smaller sized diamonds. For instance, a one carat diamond will cost more than two half carat diamonds of equal colour, clarity and cut. However the weight of a diamond is but one of the factors used to value a diamond, and it should be understood that two diamonds of equal weight may have very different values, depending on their cut, clarity and colour. In fact, a smaller but perfectly cut diamond of whiter colour and flawless or near- flawless clarity can be more valuable than a larger diamond with a weaker shade of white and less clarity.
What to consider when deciding on diamond size :
It can often be difficult to choose between the size and the other criteria of a diamond but by considering the following factors your decision may be made
While diamonds can be found in almost every colour of the rainbow, colourless diamonds remain the most popular. When describing the colour of a diamond reference is being made to the degree of colour found in that diamond. The less colour displayed in a diamond the better the colour grade. The notable exception to this would be in the case of fancy coloured diamonds, such as pink, yellow, green and blue. In fancy coloured diamonds a strong presence of colour would improve the diamond’s colour grading. Diamonds displaying little colour will allow more light to pass though, creating a prism effect, with its spectrum of colours and flash, known as fire. Diamonds are allocated a grade according to the level of colour they possess. This grading is alphabetical, starting with a D grade given to colourless diamonds and further movement down the alphabet for diamonds with progressively larger amounts of colour, ending in a Z+ grade.
A word on fluorescence
Fluorescence is the reaction of some diamonds to exposure of UV lighting. Generally it has been understood that fluorescence makes clear diamonds appear as cloudy and yellow tinted diamonds appear as clear when subject to UV lighting. Under normal lighting conditions fluorescence is not detectable. However, the presence or absence of fluorescence has had only minor importance in the purchasing decisions of most diamond buyers. This is because of the following :
Our suggestion is that buyers who are able to purchase colourless or near-colourless diamonds at reduced prices because of the presence of fluorescence, should seriously consider this option.
As a product of nature diamonds may bear traces of the pressure and processes involved in their formation. These traces may appear on the diamond either externally, or internally and are referred to as "inclusions". Where appearing internally on the diamond these inclusions may include air bubbles, cracks and non-diamond mineral deposits. Inclusions appearing externally may include scratches, pits and chips. Not all diamonds have inclusions, and those without, are rare and often the most expensive. Diamonds with inclusions are graded according to the amount of inclusions detected. Diamonds are graded for clarity under 10x magnification. Grading is allocated to a range of diamonds from "Flawless" to "Included-3" according to the following the following grades:
Each diamond's inclusions are unique to that diamond, with no two diamonds displaying the exact same inclusions. The Gemological Institute of America (GIA) diamond grading reports include graphic illustrations of inclusions found in diamonds. These graphic illustrations match the inclusions actually found in the diamonds, providing each diamond with its own "diamond fingerprint".
While certainly setting the ultimate standard in an ideal diamond, flawless diamonds are not alone in providing exquisite diamonds. Generally, all of the grades, excluding the "I" grade, will be more an indication of a diamond's value than its unmagnified appearance. In other words, despite differences in grading, these diamonds will display few outward differences. We suggest you choose a diamond that is "eye-clean" – not visible to the naked eye. "Eye-clean" diamonds are those in IF – SI2 clarity grading ranges. Some brief details about these diamonds may assist you in making your decision :
Cut is a reference to the proportions, symmetry, polish and shape of a diamond. It is the cut of a diamond that will influence the diamond's reflective character. This is the extent to which a diamond will reflect light from within itself, from one mirror-like facet to another, and then disperse it though the top of the stone, known as a diamonds "brilliance". A diamond with well cut angles (symmetry) and a good finish will enhance the diamond's light and brilliance. In a well cut diamond, light enters through the table and travels to the pavilion where it is reflected from one side to the other before being reflected out of the diamond though the table. A well cut diamond will reflect all of the light back causing the stunning brilliance that makes diamonds so alluring. In a poorly cut diamond, light enters through the table and travels to the pavilion and then "leaks out" of the facets at the sides or bottom of the diamond. A reduced amount of light is reflected out of the diamond through the table, with reduced brilliance.
Due to the importance of cut, a range of cut grades between well cut and poorly cut diamonds has been developed. The AGSL (American Gem Society Laboratory), HRD (Antwerp Diamond High Council) and GIA (Gemological Institute of America) use different standards when grading a diamond’s cut, and at present only allocate a Cut Grade to round diamonds. Despite the minor differences between the various grading systems the following different cut grade descriptions are broadly accepted by the diamond industry:
