Pink Investment Diamonds
Pink diamonds aren't just pretty stones. They're statistical freaks of nature, accounting in 2009, for example, for just 30,000 of the 160 million carats of rough diamonds produced - less than 0.02 per cent of the total. In addition, supply is limited - a point jewellers and producer Rio Tinto exploit to the full.

An estimated one-quarter to one-third of all diamonds exhibit fluorescence and yet it remains somewhat contentious.
By Ettagale Blauer
Fluorescence evokes words more usually associated with psychiatric disorders. The molecules in a fluorescent diamonds are said to be unstable, excited and structurally defective. That’s a heavy burden for a beautiful gemstone. These terms all relate to the presence of nitrogen-related defects, which lead to fluorescence. When a fluorescent diamond is viewed in ordinary light, it shows its normal qualities of colour and clarity. When such a diamond is placed under an ultraviolet (UV) light, however, it fluoresces, appearing to glow with another colour, most commonly blue. Since this quality disappears once the diamond is returned to a natural light source and ‘relaxes’, the fluorescence is a temporary condition. However, fluorescence‘s ultimate ability to permanently affect the overall appearance of the stone under normal lighting conditions is the issue that arises when diamonds are priced.
