3. What is diamond and why is it special?


 Diamond derives its root from the Greek word – “adamas” meaning unbreakable.

 Recognized first in India along the rivers Penner, Krishna and Godavari, their existence is

 dated back 6000years. Diamonds have a lot of uses; namely for adornment, scientific

 experiments, drilling and cutting.

 This priceless rock’s most popular usage is in adornment. Now the question is are they

 expensive, unavailable and unaffordable? NO. A diamond is not just a precious stone or a

 piece of expensive jewellery anymore; it’s a communication of emotions. A diamond is a

 commitment, a promise, an investment and a sense of security to your near and dear ones.

 It is a sign of empowerment to women and men alike all over the world. Gone are the days

 when diamonds were only available to a privileged few.

 With RC Diamonds, if you want it, we provide it.




4. How to buy diamonds online?


A few tips can give an edge over others while selecting a diamond. While selecting a white

or colourless diamond one follows the trusted 4 C’s of selecting a diamond. It is said that

while white or colourless diamonds are the most desired, yet coloured or fancy diamonds can fetch

higher prices or be nearly worthless. Some important pointers to help you guide in the right

direction whilst selecting a coloured diamond:

  1. Reds and pinks: The rarest of colours, these diamonds get their ruby hues thanks to an irregular atomic structure.
  2. Blues: Coloured by trace amounts of boron, blues include the allegedly cursed Hope Diamond and the Blue Heart Diamond, both today held by the Smithsonian Institution in             Washington, D.C.
  3. Yellow: Nitrogen, usually an unwanted quality in mostly colourless natural diamonds, can create expensive, vivid canary-yellow diamonds.
  4. Green: Radiation causes the colour, but gemmological labs often cannot determine if the radiation was natural or man-made.
  5. Champagne, cognac or chocolate: Skip these newly popular colours.

Some advantages of purchasing online:

More options – You get the offerings from a lot of vendors at one place

Competitive Prices – There are many instances when you can get a much lower rate for a really good stone because of lower cost of operation.

    tracks around a gemstone centrepiece. This shape is similar to emerald shape.


The Trilliant DiamondThe Trilliant Diamond

The Trilliant Cut is one of the unusual cuts and the diamond with this shape displays

a very sharp brilliance or fire. This triangular shaped diamonds may either have pointed corners or

more rounded corners.




7. Carat:

Carat (ct.) refers to the unique unit of weight measurement used exclusively to weigh gems

and diamonds.

Carat weight is often confused with visual size even though it is actually a measurement of

weight. Depending on the shape and type of gemstone being weighed, the weight will

visually show itself differently. For example, a 1.00 ct. round diamond will measure around

6.5mm, and a 1.00 ct. round sapphire will measure around 6.0mm. This is due to the varying

density of different gemstones.

Once cut, colour and clarity grade have been determined, the carat weight of a diamond can

be easily established to fit within a budget. Carat is often confused with size even though it

is actually the unit of weight of a diamond. Larger diamonds are much more valuable

because they are discovered in nature much less frequently than small ones. Diamond

prices actually rise exponentially with carat weight rather than linearly. For example, a 1.00

ct. diamond of a given quality is always valued higher than two 0.50 ct. diamonds of the

same quality. In fact, a general rule of thumb is that a diamond of double the weight costs

around four times more.

“Under-sizes” are diamonds that weigh just below a cut-off weight. While fewer exist, they

may represent an enhanced value. They are more difficult to find as a diamond cutter will

choose to sacrifice beauty in order to cut a diamond with a weight that reaches one of the

cut-off weights, or “magic numbers” as they are known in the industry. The cut-off weights

are 0.50 ct., 0.75 ct., 0.90 ct., 1.00 ct., 1.50 ct., and 2.00 ct.

Total carat weight (t.c.w.) is a phrase that represents the total weight of all diamonds or

other gemstones in a piece of jewellery, when more than one gemstone is used. Diamond

solitaire earrings, for example, are usually quoted in t.c.w., indicating the combined weight

of the diamonds in both earrings.

Diamond Carat Size Guide

Our Diamond Carat Size Guide demonstrates how diamonds of various carat weights appear

when viewed from the top down. Since carat is a unit of weight, not all diamonds of equal

carat weight will appear to be the same size due to their differing measurements.




8. Colour:


Colour refers to the natural body colour of a diamond and not to the reflection of spectral colours that flash when a diamond moves.

Most diamonds naturally exhibit slight hints of yellow, brown, or gray. This colour is caused

by natural trace elements of nitrogen that were present when the diamond formed under

the Earth’s crust. The less colour a diamond exhibits, the higher the rarity, and therefore the

higher the value. After cut, colour is the next most important characteristic to consider

when choosing a diamond. Diamonds with fewer colours allow more light to pass, releasing more brilliance and fire.

A diamond acts as a prism by dividing light into a spectrum of colours. It refers to a range of D-J colours and reflecting this light

as colourful flashes called dispersion or fire. Similar to looking through coloured glass, colour in a diamond will diminish the spectrum of colour,

or fire, emitted by acting as a filter. A diamond with a higher colour grade, i.e., one with less colour, demonstrates more colourful fire.

The international gemmological colour scale begins with the highest rating of D for colourless,

and travels down the alphabet to grade stones with traces of very faint or light yellowish or brownish colour.

Diamonds with grades D through F are considered "colourless," G through J are considered "near-colourless," K

through M are "slightly yellow," and N through Y are referred to as “light yellow or brown.”


The chart defines the grade and classification of the different colors:



Absolutely colourless or "icy white". The highest colour grade, extremely rare and most



Colourless. Only miniscule traces of colour can be detected by an expert gemmologist in a

controlled environment, a very rare diamond.


Colourless. Slight colour detected by an expert gemmologist, but still considered a

colorless grade, a rare, high quality diamond.


Near-colourless. Colour may be noticeable compared to diamonds of better grades, but

offers excellent value.


Near-colourless. Colour slightly detectable when compared to diamonds of better grades, a

good value.


Slight or obvious colour.




9. Clarity

Clarity refers to how clean or clear the diamond is with respect to natural microscopic

characteristics that were trapped within or on the diamond while it was forming.

Internal characteristics are known as inclusions, and characteristics on the surface of the

gem are known as blemishes. Inclusions may be crystals of a foreign material or structural

imperfections such as tiny cracks, known as feathers, which can appear whitish or cloudy.

Often times the inclusions are microscopic diamonds that were absorbed by the larger

crystal before the diamond was carried to the surface of the Earth. The quantity, size,

colour, location, orientation, and visibility of inclusions all affect the final clarity grade of a

diamond. Diamonds with no or few inclusions are considered particularly rare and highly


When gemmologists inspect diamonds for clarity, they use a maximum of 10x magnification and only

judge the diamond face up. If an inclusion is not visible when the diamond is viewed from the top,

then it cannot be used in determining the clarity grade. Gemmologists use microscopes and loupes

(small handheld magnifying lenses) to determine the size, type, and position of the inclusions.

Experienced graders use 10X magnification to identify the various clarity characteristics, and

to map their location on “diamond plots.” These plots are like small maps for each individual

diamond, and are used to identify each individual stone. No two diamonds will ever have

the same internal pattern, and the plots work as a form of individual identification much like

a fingerprint.

Clarity grades applied by expert graders are as follows:


No internal or external flaws (FL). Flawless with no internal flaws (IF). Extremely rare and



It is very difficult for a trained gemmologist to locate under 10x magnification.

Characteristics referred to as minute.

VS1, VS2

Difficult to see inclusions under 10x magnification, unless pointed out by a trained

professional. Typically one cannot see inclusions with the naked eye.


Inclusions are potentially identifiable under 10x magnification, but are rarely visible with the

unaided eye. Characteristics referred to as noticeable.


Inclusions are easily visible under 10x magnification and may be visible with unaided eye.

Characteristics should be referred to as noticeable or obvious.

I1 - I3

Inclusions are visible to the unaided eye.




10. Cut:

Cut is considered to be the most important of all of the diamond characteristics, as a well-

cut diamond will often appear larger than a poorly cut diamond of the same carat weight,

and have the appearance of enhanced colour and clarity.

The quality of cut is determined by how well the symmetry, polish, and proportions of the

diamond produce the most attractive balance of the three different types of reflection.

Several proportion factors have the most immediate impact on a diamond's ability to reflect

light correctly. The table size and depth of a diamond relative to the diameter greatly

impacts the light return from a diamond. A well-cut diamond is proportioned so that most

of the light entering the gem exits back through the top of the stone, perfectly balancing the

white light (brilliance) with intense flashes of fire (dispersion). A poorly-cut diamond, with

facets cut only a few degrees out of alignment, can result in light exiting through the bottom

of the diamond, known as light leakage, instead of from the top where it is visible. This

creates a diamond with dulled brilliance from poor light performance within the gem,

making the center of the gem look dark.

The best cut diamonds have proportions that are within tried and true ranges known for

maximizing brilliance, fire, and scintillation. The cut grading scale for diamonds is based on

the reflective properties of the diamond, according to these carefully calculated diamond

measurements. It also allows you to easily identify a well-cut diamond, without having to

assess each individual cut characteristic.



Exquisite quality cut to create the optimal combination of brilliance and fire. Reflects nearly

all light that enters the diamond. Top 3% of diamond quality based on cut.

Very Good

Superior quality cut that reflects nearly as much light as the ideal cut while at a substantially

lower cost. Top 15% of diamond quality.


Premium quality cut to optimize the size without sacrificing quality or beauty. Reflects most

light that enters. Top 25% of diamond quality.


Adequate quality cut which reflects some light while maximizing weight. While not as

brilliant as a good cut, still a quality diamond. Top 35% of diamond quality.


Inadequate quality cut that reflects minimal amount of light.


          A diamond’s cut grade is actually a combination of three different types of reflection.



Brilliance, or brightness, refers to the white light that is reflected back to the eye from the

diamond. Light enters through the top of the diamond (the table), is broken down into a

rainbow of spectral colours, and is reflected back and forth in the interior of the gem by

bouncing off the mirror-like facets. Light exits through the table, recombining as white light.

Some important facets:

Dispersion (Fire):


Dispersion is the rainbow of colours that is reflected back to the eye from the diamond.

Light enters through the top of the diamond, is broken down into a rainbow of spectral

colours, and is reflected back and forth in the interior of the gem by bouncing off the mirror-like

facets. When it leaves through the crown, it stays separated and reaches the eye in flashes of colour.




Scintillation is the play of light you see with movement of the diamond, demonstrated by

sparkling on the diamond’s surface. A diamond is evaluated on its ability to reflect and

refract light in all directions.


11. Certification
