Education - The Four C's

Cut | Colour | Clarity | Carat

The Four C’s imbue a diamond with brightness, sparkle and life.



The most important element of the four C’s. The angles and finish of a premium cut diamond enhance it’s ability to reflect light. This give the diamond its sparkle, brilliance and fire.


Light enters a well-cut diamond through the table on top and travels into the diamond’s pavilion where it reflects light to make a kaleidoscope effect.


The light then exits the diamond through the table and meets the observer’s eye with the flashing, fiery effect which makes the diamond so remarkable.


The brilliance is greatest in an ideal cut diamond.

Diamond Education



The most desirable colour in a diamond is colourless. The colourless diamond is prized for its ability to reflect light and generate sparkle and brilliance. The colour grade begins with D for colourless and continues though to Z which is light yellow.


D-E-F: Colourless. This is the colourless diamond group. It  commands the highest prices. D and E show virtually no colour and are clear like glass. F starts to show a trace of colour and is the transitional colour to the next group.

G-H-I-J: Near colourless. This is the near colourless group. These diamonds begin to exhibit a very light shade of colour, but it is hard to detect in mounted stones.

K-L-M: Faint yellow. This is the group that begins to show slight yellow colour which may be noticeable from the top of the stone and even more from the sides.

N through R: Very light yellow. Diamonds in the N-R group show yellow colour even when mounted in jewellery. Determining the exact colour of a diamond in this group is not important since their prices are similar. Certificates for diamonds in the N-R group are uncommon because of their relatively low price.

S through Z: Light yellow. Diamonds in this group show substantial colour when loose or mounted. S-W range diamonds bring the lowest prices in the colourless-yellow market. Diamonds around the X-Y-Z range and lower are rare and have a very appealing yellow colour causing their price to rise (fancy yellow).

Clarity is the pureness and absence of flaws in a diamond. A high-grade quality diamond has no scratches, pits or blemishes on the surface or internally. This enables light to travel through the diamond, enhancing its brilliance and luminosity. Perfect clarity is rare. Internal flaws are impurities that reside in the interior of the diamond. Three of the most common flaws are crystal, cloud and feather.

Carat is the measure of a diamond’s weight.

A metric carat is equal to 0.2 Grams or 200 Milligrams. A carat is divided into 100 points:
1/4 ct. = 25 points = .25 ct.
1/3 ct. = 33 points = .33 ct.
1/2 ct. = 50 points = .50 ct.
3/4 ct. = 75 points = .75 ct.

As a diamond's weight increases, the price per carat increases to reflect the fact that larger diamonds are more rare.
