The physical and chemical properties of diamond make it a suitable material for semi-conductors and bio sensors in the small electronic industry. The high conductivity allows high powered computer processors to run at lower temperatures than using silicon and prolong the processor’s life. They can handle high voltages in power grid switching. Toughness allows diamonds to withstand searing heat and sophisticated lasers. Diamonds resist corrosion from acids and organic compounds and are also good for biological sensors.

However, rare quality natural diamonds may be a better investment for you.

Analysts predict a 20% annual growth in demand for diamonds in China and India to continue leading to a huge $10bn shortfall in the supply of natural diamonds by 2015. Quality natural diamond jewelry therefore could be a very good investment indeed.

The 4 ‘C’s’ for natural diamonds can also be applied to synthetic man made diamonds. Self engineered man made diamonds are often labeled “cultured diamonds” leading customers to believe that they are buying a natural diamond. The fake diamond manufacturing industry can introduce carbon & other elements to increase mass but this lowers the quality of the diamond.

But beware of fakes. For your protection always obtain an original Gemological Certificate from a recognized Gemological Testing Laboratory for all gems sold as “natural” diamonds over 0.5 carats in weight.
