A Pakistani jewellery designer has hit upon a unique idea for producing platinum jewellery by using minute pieces of the precious metal to create detailed engravings.

Arshad Iqbal Mughal makes the images that are so small they can only be seen properly under a microscope and claims his designs are the smallest in the world.

He now plans to offer one of his artworks - a 100 microns picture featuring a deer - to the President, His Highness Shaikh Zayed bin Sultan Al Nahyan, according to the Khaleej Times.

Queen Elizabeth and Bill Clinton have already received similar items from the designer, with the gold designs that he has developed still being made from the same single gram of gold he bought more than 20 years ago.

The miniature masterpieces are due to go on display in London in a special exhibition from July 22-25.

The miniature designs echo the eye jewellery that appeared last year in the Netherlands, another similarly startling and minute innovation in the platinum jewellery sector.

Experts developed eyeball jewellery, or "JewelEye" as it is being called, using an innovative surgical technique to implant a special type of platinum.

The jewels, which measure just 3.5 mm across, are inserted directly into the eye, and have already been snapped up by a number of enthusiastic fashionistas.
