Whilst coloured diamonds have recently gained popularity across the industry, they have always fascinated Allen Brown and he has always used them in his work.
Coloured diamonds are rare and renowned for their dazzling beauty and are found in pinks, greens, browns, champagnes, cognacs, yellows and a full spectrum of blues. Their unique brilliance, combined with warmth and depth of colour gives them a sparkle unlike other coloured gems.
Diamonds were formed millions of years ago, by immense heat and pressure deep within the earth's surface. When diamonds formed with traces of other elements present, natural coloured diamonds were created. For every coloured diamond, there are 10,000 colourless ones.
The presence of nitrogen created yellow and orange shades to diamonds. Boron traces created blue diamonds, ranging from sky blue to deep navy. Hydrogen traces produced unique violet hues and naturally occurring radiation reacting with diamonds over millions of years created green diamonds.
Whilst clarity is important when colourless diamonds are valued, the rarity of colour, it is depth and variation of colour that is important when valuing coloured diamonds.
The Allen Brown Gallery hand-picks its coloured diamonds, from legitimate sources that comply with the Kimberley Process and UN resolutions. They are chosen for their unusual colours, as well as for their depth of colour and clarity.
