Diamond Engagement Rings Specialist

Chunlei Guo, a researcher at the University of Rochester hasn’t quite got to the ultimate alchemist’s dream – there is still a while to go before one can change dross into gold. However, what has been achieved is probably the next best thing. Using intense laser light, it is possible to change a metal’s intrinsic property when it comes to colour. So now, you can have black platinum. One can only start to imagine the immense possibilities this will throw up as far as jewellers are concerned.

The great thing is, it works on most metals and you can have any colour. So you can have aluminium which can be changed to look like gleaming gold and titanium, tungsten, silver, gold and platinum can take on any or all of the myriad hues of the rainbow. You can have stark black or you can have a multicoloured fantasy – the only possible limits where colours are concerned will be your imagination. Think of an engagement ring where the metal is a glorious burst of colours while the diamond’s white brilliance shines in the centre. Other jewellery like bracelets or earrings can all be fashioned out of metal to match any dress you might want. Once a design is made, it can be rolled out in different colours so that each one is unique.

How it works is that the laser brings about a change in the metal’s surface and there are microscale and nanoscale structures formed which can reflect any colour or combination of colours that it is fashioned to do. Of course, the strength of the laser is immense – just think of a needlepoint of laser light emitting a burst in a femtosecond (or a really micro-mini second) that the entire electric grid in the US does. Now that’s what is called blasting your way to a colourful future.
