Gold has played a pivotal role in the history of empires and countries – including our own. Its lustre and enduring qualities mean that gold has been treasured for millennia, and is still highly valued today. As it doesn’t corrode, gold, like diamonds, has come to symbolise everlasting love.

As well as being an adornment, gold plays a vital role in the stability of the world economy as a store of value. Central banks keep gold reserves to support the value of their currencies, and owning gold yourself (in the shape of bullion or Krugerrands) can help you achieve your own financial stability.

Gold is a remarkable metal: it is so malleable that it can be hammered into a thin enough sheet to be transparent. The visors on astronaut helmets contain very thin sheets of gold, for example. Gold is very ductile, which means that it can be drawn out into a very thin wire. It is also an exceptionally efficient conductor of electricity.

It is believed that 85% of the gold ever mined can still be traced. Every ounce of gold ever mined could fit within a cube with sides of just 20 metres.

Gold’s value is due in part to its scarcity, but also its importance in banking and its usefulness in technology manufacturing.

Gold jewellery can be melted down and reshaped into a new creation (also this results in a 10% loss by weight). This capacity for reinvention further adds to gold’s appeal and fascination.

While the price of gold can fall as well as rise, the longer-term trend is one of an increase in value. There is a ready market for pre-owned gold, and with data on its value readily available, gold is easily bought and sold through licensed dealers like Krugers & Gold.

We are able to give fair and accurate valuation on all grades of gold. The valuation will reflect the weight of the gold, but also its purity. Gold purity is measured in karats (k), with 24 karat gold being pure (but also rather soft). Because of this, gold is often mixed with small quantities of other metals to create gold alloys of varying purity – but increased hardness. Typical purity levels are 18ct (often used in fine jewellery) and 9ct (used in entry-level gold jewellery.

Metals such as copper, nickel, silver and palladium are used in the creation of gold alloys. The metal used, and the proportion, affects the colour and properties of the gold. The lower the karat number, the lower the amount of gold by weight.

Gold plays an important part in human culture, from Olympic gold medals to wedding rings to being synonymous with quality and achievement. The city of Johannesburg was founded on gold, and many people have gold dental fillings. The smartphone you’re using to view this website contains around 50mg of gold contacts, worth around R6.50

The story of gold is as old as civilisation, and it will endure longer than all of us. If you own gold and want to convert it into cash, our buying process guarantees you privacy and security.


Like gold, silver is a precious metal with a long and fascinating history. The value of silver is significantly less than gold, which means that silver coins and bullion are therefore a more accessible way to invest in precious metals.

As with gold, silver’s uses reflect its beauty (jewellery and cutlery) and its properties (solar panels, water filtrations and – as silver compounds – as an anti-microbial).

The value of silver is – as you would expect – a function of both quantity and quality. The most common purity of silver is sterling silver, which is 92.5% pure. Jewellery made from sterling silver carries the hallmark ‘925’.

Silver has numerous cultural associations, such as the superstition that werewolves can only be killed by a silver bullet. The term ‘silver bullet’ has come to mean a guaranteed, almost magical answer to a problem.

Our precious metal experts are as familiar with silver as they are with gold and can give you an equally accurate and fair valuation of your silver jewellery.


Diamonds – the most precious of all gemstones – were formed deep inside the Earth by extreme heat and pressure. These carbon crystals were subsequently transported to the surface – or close to it – by volcanic action.

Diamonds are renowned for their hardness – because of this, they are used in industrial cutting equipment. More famously, diamonds are used in jewellery such as engagement rings. Diamonds have inspired one of the world’s most famous marketing slogans: ‘A diamond is forever’, and the most famous stones are surrounded by a swirl of myths and legends.

These precious stones have played a vital role in the history of South Africa – just like gold. The ‘Great Hole’ at Kimberley is a scar in the landscape from former diamond mines.

Diamonds have represented some of history’s greatest romances – and inspired some of its most audacious crimes. Famous diamonds include the ‘cursed’ Hope Diamond, and the South African Cullinan Diamond, which is now part of the British Crown Jewels.

Cut diamonds have a sparkle like no other stone, which is why they came to symbolise the enduring love between two people. As well as the ‘4Cs’ criteria, unusually coloured diamonds can also attract a premium. There is currently a vogue for pink diamonds, which can be worth millions of Rand.

At Krugers & Gold, we appreciate the beauty of diamonds and we are always ready to assist you with an impartial, accurate valuation of your loose stones and set diamonds.


Platinum is a precious metal that is mined in South Africa and plays a vital role in our country’s economy. South Africa accounts for around 80% of world production of platinum, which is mined in much smaller quantities than gold or silver.

Like gold, platinum is malleable and ductile, and very unreactive, which means that it doesn’t tarnish or corrode.

Almost half of all platinum is used in vehicle catalytic converters, with jewellery also being an important use. Platinum wedding rings have become more popular as an unchanging symbol of never-ending love.


Palladium is one of the platinum group metals, and also a precious metal. Its main use is in catalytic converters, but it is also an important alloying metal in the production of white gold. Palladium coins and bullion are rarely encountered, but if you own any white gold, you probably own some palladium.
