Faq

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.

Does Size Count?

The larger the stone, the more rare and higher the price per carat

When Less Is More

The less colour the better. Light refacts more through colourless stones, giving greater rediance.

Keeping It Clean

Light travels better through clean windows. The clearer the stone, the higher the price

All In The Angel

The better the cut, the greater the sparkle.Precise angles maximise brilliance and add extra value.

Carat Weight

Does Size Count ?

+2.00- +8.2 mm
Eye - caching and gorgeous
a statement in itself

1.00ct- +6.5 mm
Most favoured size for
solitaire engagement rings

0.50ct- +5.2 mm
Excellent size for Diamond
Pendants and earrings

The Larger the stone, the more rare, and the higher the price

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

  • Personal preference – do you or your loved one prefer to wear larger pieces of jewellery?
  • Finger size – slender fingers can make diamonds appear larger than their actual size;
  • Physical activity – a person who is very physically active will more likely knock or bump their ring;
  • Setting style – will the selected setting be aesthetically suitable to the diamond ?

Colors

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.

The colour grades can be described as follows :

  • D, E & F grades :
    These are clolourless diamonds. Only experienced diamond graders are capable of differentiating between D & E colours, and then only if these diamonds are unmounted. Diamond graders can more consistently identify F colour diamonds.
  • K, L & M grades :
    Most consumers will be able to identify color in these diamonds, when mounted. However when these diamonds weigh less than half a carat and are mounted in white metal, they may still appear as clourless.
  • O –Z grades :
    Most consumers will be quick to notice colour in these diamonds, regardless of how the diamond is mounted. These diamonds will range between a very-light yellow and a light yellow, however brown and grey tones may also be identified.

What to consider when deciding on your diamond’s colour :

  • Where your setting is in yellow gold you may be ableto choose a lower colour grade than if you were choosing a platinum or white gold setting
  • Yellow shades, found in K-M graded diamonds, may draw out the latent character of a jewellery piece, depending on the piece selected.

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 :

  • Fluorescence is only detectable under UV lighting;
  • Under UV lighting even trained gemologists are unable to consistently agree on the effects of fluorescence and;
  • Some buyers prefer the aesthetic effect of fluorescence.

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.


Clarity

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:

  • FL (Flawless) :
    No internal or external flaws;
  • IF (Internally Flawless) or LC (Loupe Clean) :
    No internal flaws but some surface flaws;
  • VVS1-VVS2 (Very Very Slightly Included) :
    Tiny inclusions which are very difficult to detect under 10x magnification;
  • VS1-VS2 (Very Slightly Included):
    Tiny inclusions which are difficult to detect under 10x magnification;
  • SI1-SI2 (Slightly Included) :
    Tiny inclusions which are detectable under 10x magnification;
  • I1-I3 (Included) :
    These inclusions are detectable under 10x magnification, and are also visible to the human eye.

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".

What to consider when deciding on your diamond's clarity :

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 :

  • VVS and VS graded diamonds are more expensive but are excellently valued, with difficult to detect inclusions;
  • SI1 and SI2 graded diamonds are more affordable with inclusions that remain almost invisible to the naked eye;

Cut

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.

Cut Descriptions

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:

  • Ideal Cut
    Ideal cut diamonds maximize the brilliance that is reflected out of the table of a diamond. This maximum brilliance is achieved through the exact calculation of the diamonds symmetry and proportions. When finished with the highest standards in polishing of the surface of the stone, these diamonds become the best available.
  • Excellent Cut
    While generally also displaying maximum brilliance, excellent cut diamonds are not as exacting in terms of their symmetry and proportions.
  • Very Good Cut
    In a very good cut most of the light that enters the diamond will be reflected back though the table, creating a high amount of brilliance. Craftsmen working on these diamonds would have made the decision to stray slightly from the proportions and symmetry of ideal cut and excellent cut diamonds, to create a larger diamond. For example a very good cut diamond may have a table size or girdle width that does not comply with ideal cut or excellent cut diamonds. However, in many instances, very good cut diamonds will possess symmetry and proportion characteristics that overlap with those of ideal cut and excellent cut diamonds. These diamonds provide a very good value purchase for buyers seeking a slightly larger diamond for the same price as ideal cut and excellent cut diamonds.
  • Good Cut
    These diamonds will reflect much of the light that enters them back through the table. In such diamonds the craftsmen have significantly deviated from the proportions of ideal cut and excellent cut diamonds to create the largest possible diamond from the original rough crystal diamond. By way of an example these diamonds may have a crown angle or depth that is further deviated from the proportions acceptable in a very good cut. These diamonds may provide the option of a larger diamond then a very good cut diamond for the same price.
  • Fair and Poor cut
    A fair or poor cut diamond will only reflect a small amount of the light that enters, back though the table. Most usually these diamonds have been cut where maximum carat weight was the most important criteria.
