What do diamonds have to do with tennis? According to Wikipedia, in 1987 champion tennis player Chris Evert was wearing a thin, diamond bracelet made by famous jeweller George Bedewi. During the match the braclet snapped, and play was halted so that Evert could find the diamonds. From then on, that style of bracelet gained the name ‘tennis bracelet’ and became increasingly popular.

What a great story! We’ve got our own special diamond tennis bracelet letting you save almost £1000 on the RRP.

Selling your scrap gold is a fantastic way to make some extra cash. Whether you have a ring you never wear or a necklace that’s become tangled and broken, you can exchange it for money quickly and easily. You might even want to invest in some new jewellery with the proceeds.

At 750 we buy gold jewellery of all carat values. The price we pay depends on the gold content, the weight of the item, and the price of gold on the day we receive it. An 18ct gold ring will be worth more than a 9ct ring of the same weight, for example.

Gold is increasingly seen as a good investment because the value has gone up over recent years, so your unwanted jewellery might be worth more than you think. At the same time, the price of gold fluctuates day to day, but we do publish a to the sort of price you can expect.

Diamonds occur in many different colours, from pink through to brown, orange and blue. However, most diamonds of gem quality appear on a scale from colourless to yellow. The most intensely coloured diamonds are called ‘fancy’ and there’s an increasing market for them. Colourless diamonds have traditionally been popular, especially for engagement rings and the fewer the flaws within the diamond, the more precious the gem.

Diamonds are rated on a special scale, under magnification so that any internal flaws can be seen. Completely colourless diamonds are the rarest and most expensive - diamonds with flaws become more affordable as the number of flaws increase.

Hallmarks have been used in Great Britain as a form of consumer protection since 1300 AD.

Each symbol stands for something different; one says how pure the metal is, one records the year of manufacture, one records which assay office was used and one records the manufacturer of the piece.

Before a piece of metal can be hallmarked it must be tested (or assayed) by one of the UK’s four assay offices. All precious metals have to be hallmarked by law. There are three compulsory hallmarks:

The sponsor’s mark shows the company who sent the item for testing.

The assay office mark which shows which assay office has tested the item.

The standard mark shows the standard of the precious metal. For silver this is 925 and for 18ct gold it’s 750.

Each UK assay office has its own hallmark:

The leopards head is for London, the anchor for Birmingham, the Yorkshire rose for Sheffield and the castle for Edinburgh.

Since 1478 the hallmark has included a date letter indicating the year of hallmarking - this is unique for each year - when the alphabet has been used the style of the letter changes.

The final mark is the Fineness symbol. This is a traditional symbol denoting the fineness of the metal. It is a lion for silver and a crown for gold.

The H=hallmark for gold is now governed by the 1973 Hallmarking Act.
