Cut is a key factor to consider when looking for top quality diamonds. It refers to the symmetry, proportion and polish of a diamond.
A well cut diamond is easily recognised by it’s beautiful shine and sparkle. If the diamond cut is too shallow, the light will escape at the bottom of the diamond and not reflect back up, therefore losing its sparkle.
A diamond’s cut grade weighs the combined impact of a few factors, making it a simple and effective tool to use in evaluating diamonds.
The colour of a diamond refers to the body colour of a diamond. Diamonds come in different colours such as blue, pink and yellow but the most common colour for engagement rings is white . Diamond colours are categorised using letters to indicate their colour, with the earlier letters indicating a more colourless diamond. The letter categories are:
G-J: Near Colourless
K-M: Faint Colour
N-R: Very Light Colour
S-Z: Light Colour
Diamonds are made under extreme pressure which creates small imperfections within the diamond. Clarity measures how flawless and clear a diamond is. Diamonds with more imperfections stop the route of light through the diamond also, affecting it’s shine.
The diamonds are categorised in different groups:
IF: Internally Flawless
VVS1 & VVS2: Very Very Slightly Included
VS1 & VS2: Very Slightly Included
SI1 & SI2: Slightly Included
I1 & I2 & I3: Included
Carat is the unique unit of weight measurement given to a diamond, not the visual size of it. This is a common misconception when customers are comparing diamond sizes. The price of a diamond depends on how many carats a diamond has. The more carats a ring has, the more expensive it will be.
Carats typically range from 0.25 to 2.00, with 0.25 being the smallest carat at 4.1mm. It is important to remember that even though there are guidelines for carats, all diamonds are unique. Two diamonds may look the same but have totally different characteristics!
Most diamonds are sent to the official bodies Gemological Institute of Australia or HRD Antwerp Grading, for diamond certification.
GIA and HRD tests the quality of the diamonds. They grade the diamonds on different aspects such as cut, colour, clarity and carats. The diamond certification gives the purchaser the peace of mind that the information about the diamond they receive is trustworthy and reliable.
There are different factors that influence the cost of a diamond. These include quality indicators such as cut, clarity, colour and carat.
The shape of the diamond affects the cost as well. Shapes include teardrop, princess, round and many others. The round shape diamond is the most popular, which makes it more expensive than other diamonds. It is also expensive due to how the shape is achieved. Much more raw material is needed to cut the diamond, and so a bigger and more expensive diamond is needed.
