To create a natural diamond, you need a concentrated form of carbon exposed to extreme heat and pressure, usually over millions of years. Diamonds are the hardest material known to man and can only be scratched by another diamond. The rough diamond formed from this process then needs to be polished or cut into a diamond that sparkles and higher quality diamonds are then sent off for diamond grading certification. We have provided a large amount of information about diamonds in our diamond education section as we offer one of the largest selections of polished and certified diamonds in the world. All our diamonds are conflict free diamonds and comply with the industry's strict Kimberley process regulations. Our diamonds originate from Canada, Russia and Africa.
Brilliant Cut Round Diamond
A brilliant round cut diamond is the classic and timeless choice for a diamond. A well cut round will sparkle brilliantly, and it is suitable for both classic, vintage and contemporary engagement rings and most jewellery designs.
Princess Cut Diamonds
A princess cut diamond is a cousin of a round diamond, although more modern it is also a brilliant cut which means it has major sparkle factor. It is also at home in classic, modern and vintage engagement rings and jewellery designs.
Emerald Cut Diamonds
Emerald cut diamonds are unique in their clarity, rectangular in shape, they have a large table and large facets across the entire diamond making them the purest looking of all the diamonds.
Oval Cut Diamonds
The oval cut diamond is similar to the round brilliant cut, but is an elongated version of the round. The oval diamond designs are over 200 years old but the modern version was invented in 1960s.
Pear Cut Diamonds
The pear shape diamond is a modified brilliant cut and is a cross between the Oval and the Marquise cut resulting in a sparkling tear drop diamond. It dates from around the 17th century.
Cushion Cut Diamonds
The cushion cut diamond is also known as the pillow-cut diamond because of its resemblance to a pillow. Cushion cuts were very popular during the 1800's and fell out of favour until a more recent revival. Their origins lie in the so-called Old Mine Cut, which was a square cut with rounded corners.
Asscher Cut Diamonds
The asscher cut diamond is a square emerald and was created when Joseph Asscher was commissioned by the Royal Family to cut the Cullinan diamond the world's largest diamond (3,106 ct). This cut was popular up to 1920's but declined subsequently up until 2001, when it was re-launched in a new and improved version with additional facets.
Other Cuts
On the more adventurous side, there are many other diamond shapes such as the radiant cut diamond, heart cut diamond or marquise diamond cut.
