When buying a diamond there are a few things to take into consideration. Diamonds are available in various colours, shapes and sizes but you should be aware of the 4 major factors when buying a diamond.

These 4 attributes are commonly referred to as the 4"C's" they relate to COLOUR, CLARITY, CARAT and Cut

The most desirable diamonds are those that achieve the highest rating in each of these categories:

Colour

Most diamonds are white or colourless but can also range from pink to yellow and light brown to black.

Diamond colour grades start at D and continue through the alphabet . The closer colour to D, therefore the whiter the diamond, the more valuable the stone.

Clarity

When relating to the clarity of a diamond it refers to the size and amount of inclusions, marks or flaws within the stone. Diamonds are made from crystallised carbon and almost all diamonds will have tint traces of non-crystallised carbon that may appear as minute black flecks. Most inclusions are almost invisible to the naked eye and a magnifying glass is needed to see them. The way diamonds are clarified in terms of clarity range from Flawless, VVS, VS, Si or pique, with flawless being the rarest.

Carat

The carat refers to the weight and size of the diamonds. It is the unit of weight by which a diamond is measured. Large diamonds are rare and therefore more expensive than smaller diamonds. A 1ct diamond is also known as 100 points. A 1/2 carat diamond is equivalent to 50 points.

Cut

The cut refers to the way the diamond is presented. There are many different shapes such as Round, Princess, Oval, Heart etc with the Round Brilliant Cut being the most popular.

It is also important to take into consideration the proportions of the diamond. Stones that are too deep or too shallow will not be worth as much as a stone that has been recognized as having the correct proportions.

As the exact science of determining a diamond grading is still quite subjective we use the highly regarded Gem Studies Laboratories in Sydney to value our diamond jewellery.
