Britain’s biggest jewellery robbery saw £40 million worth of diamonds stolen from Graff Diamonds in Mayfair. In total 43 bracelets, necklaces, rings and watches were stolen in less than two minutes.

Det Supt Stuart Cundy, of Scotland Yard, said that he was keeping an "open mind" about the robbery and had considered that the diamonds may have been stolen to order or that the criminals were helped by an insider. Det Insp Jason Prins added: “The items that were stolen will be very difficult to sell on the open market so I think there was already a market in place.”

The suspects, dressed smartly in suits, were dropped off at Graff Diamonds in central London in a black cab last Thursday afternoon and walked straight past a security guard. It is thought that they had made an appointment to visit the store using a false name. The suspects’ images have been circulated to all ports and airports but police believe they will have organised an escape route and may already have left the country.

A former head of the Flying Squad, told The Telegraph: “It has all the hallmarks of a well-executed, well-planned raid. Because of the specific nature of the articles they went for I think there would have to have been insider knowledge involved and good reconnaissance prior to the raid.”

The term jewellery can be used to simply describe an item of personal adornment such as earrings, bracelets, necklace, silver charms, etc. These adornments has been part of history since very early times.

Back then jewellery was nothing compared to how it looks today due to the lack of knowledge to handle precious metals, in some instances these metals were not discovered at the time. Original jewellery pieces were created using natural materials such as shells, wood, carved stones, animal teeth and bones.

As man evolved jewellery did also, and with the discovery of precious metals and gemstones, jewellery became more valuable and has been used over the centuries for various reasons such as:

• Currency - Many ancient civilizations at some point kept large amounts of jewellery as a form of wealth.
• Symbolism - To show status or to worship gods and goddesses, hence the Christian Crucifix or the Jewish Star of David.
• Protection - From ancient times till now people have used jewellery as amulets of devotional medals.
• Artistic Display - Relating more to modern times, towards the end of the 19th century this use became common, through the work of master jewellery craftsmen Peter Carl Faberge and Rene Lalique.

Since man started to use metals to make jewellery, alloys of almost every metal have been encountered in jewellery, for instance the Romans used bronze to make their jewellery, and bronze is an alloy of various metals with copper being the primarily metal.

Nowadays, high standard jewellery is made with gold, silver, platinum, palladium and sometimes even titanium which is known for being an extremely resilient metal, with gold and silver being the most common metals used.

Silver or Platinum alloys range from 900 (90% pure) to 950 (95%) pure and the most common type of silver used is sterling silver, hence the name sterling silver jewellery.
