High Quality Diamonds

The best quality diamonds are formed under high temperatures and pressure, 50 miles underground. They are the hardest minerals on earth with exceptional lustre and brilliant fire, making them the most sought after of all gemstones. We stock both princess and round cut diamonds. We assess the quality of our diamonds according to four factors known as the 4 C’s - colour, clarity, carat weight and cut. Cooksongold will not knowingly sell ‘conflict diamonds’ and will always try to undertake reasonable measures to help prevent the sale of ‘conflict diamonds’. All our diamond suppliers actively take part in the Kimberley Process Certification Scheme.


Diamonds are the most popular stone for engagement rings and anniversary gifts. So take a look at our range of quality diamonds for sale and you will be sure to find something that makes your jewellery designs sparkle. Check out 'Diamonds' a comprehensive and informative book of essential knowledge about the diamond industry by Marijan Dundek, from our jewellery making book range.
