Glimmering Gold – All About The Precious Metal

One thing is for certain: gold is and will always be in fashion.

Indeed, historically gold has always been one of the most popular (and valuable) precious metals worldwide. For centuries, humans have been mesmerised by gold, and gold jewellery in particular.

You might wonder: why is gold so popular – and so pricey? What does “carat” actually mean and what is actually the difference between 9-carat and 14-carat gold?

Solid gold jewellery is a purchase that you will be able to enjoy for life, even generations, so before you make a purchase it’s wise to educate yourself on the subject and learn about different strands of gold available.

Therefore, in this blog post we would like to provide you with some insightful and interesting facts about this truly stunning metal.

Pure gold is not only beautiful, it is also incredibly durable. It’s the most non-reactive of all metals and it doesn’t tarnish, rust or perish.

This is why it’s perfect for use in jewellery making and other high-status items which are intended to retain their value and finish indefinitely.

Humans have been working with gold for a very long time and it is one of the metals of antiquity which were used by prehistoric humans; there is evidence of the Egyptians using gold as far as 3000 BC.

Furethermore, it is a very workable metal which is another reason jewellers and goldsmiths love to use it in their designs.

Of course, it is also a truly beautiful metal with a luminous, rich and warm colour that no other metal can compete with.

Lastly, gold is quite rare and often difficult to extract in large quantities, making it particularly precious (and therefore both valuable and expensive).


Gold isn’t cheap, that’s common knowledge – but just how expensive is it? The date this is written, 1 gram of 24ct is priced at nearly $70 AUD. Compared to pure silver – another much loved precious metal – currently only priced at AU$0.83 per gram, gold is certainly on a whole different price level.

One thing is for certain; there is no such thing as cheap gold jewellery. If you have some inexpensive gold jewellery and you notice that it keeps turning your skin green or black, then it’s very likely to not be real gold in the first place.

What is a gold carat?

A carat – when used to refer to gold in Australia, the UK and elsewhere – is a measure of purity.

Gold is measured in 24ths, so 24 carat is 100% gold and the purest gold there is.

Essentially, the higher the carat the more valuable the gold. But when it comes to making useable objects such as jewellery, 24ct gold is generally too soft. That’s why gold jewellery is almost always alloyed with other metals to increase the toughness and hardness of the metal, and perhaps to change the colour, such as creating white or rose gold. Alloying with other metals makes the jewellery more durable and better to both work with and wear, whilst also reducing the purchase price.

9ct gold
Most day-to-day gold jewellery such as necklaces, bracelets and earrings are created from this 37.5% pure gold metal. It has a lighter colour and is both durable, long-lasting and beautiful, and also more affordable than higher carats of gold.

14ct gold
This caratage is commonly used in the United States. At 58.5% pure gold, 14K jewellery has a more intense gold color compared with lower-karat items. However, 9K pieces are harder, so if you are after durability, keep this in mind.

18ct gold
18ct gold is of 75% gold and 25% other alloyed metal/s. Appreciated for its brighter and more radiant tone, this gold is commonly used in very luxurious pieces, especially when it comes to engagement rings and special jewellery items.

22ct gold
This gold is 91.6% percent pure gold, and although relatively durable the material is very soft, which makes it best suited for simple, special occasion jewellery. Its level of purity also makes it expensive.

24ct gold
24ct is pure gold: there is no higher carat for gold. However, what many people don’t know is that you’re not likely to see it in any jewellery. Gold this pure is extremely soft and cannot hold its shape. It’s more likely to be used as an investment currency than anything else. It has a luminous, rich and warm golden colour. Given its purity, 24ct gold is also the most expensive version of gold by weight.

Different colours of gold

As you’ve seen here at Tesoro Jewellery, gold jewellery comes in a variety of different colours. These variations are all down to alloying with other metals.

Yellow gold jewellery is still the most popular jewellery colour. Classic, timeless and fashionable, yellow gold is always in style, and it’s also immediately associated with pure gold due to its color.
