Diamond Knowledge

Education Centre

Here at Diamond Elite, we have years of experience in all fields of jewellery. From diamonds to gemstones, engagement rings to tiaras. You name a piece of jewellery, and we’ve made it. All of us here at Diamond Elite apart from loving our jewellery, also have a deep love for educating our fellow humans. Our mission is to inform our customers about what it is exactly that they’re buying, what price they are buying it at, as well as other useful information about gold, diamonds, and jewellery.
Buying jewellery can be tricky, with the thousands and thousands of jewellers around the city offering different items of jewellery with different gold properties, and with all at different prices it can get a bit confusing.


Here at Diamond Elite we like to focus on 18kt Gold and Platinum as we believe it is the essence of premium high quality jewellery. But to allow for more affordable options we have also added the ability to choose your ring in 9kt or 14kt gold.

If you don’t understand the differences between all the different Gold Karats and the reason some gold jewellery can look a bit different to others, then we will explain it to you.

Gold is a metal with special properties that make it most suitable for the use in fine jewellery. Alongside Silver and Platinum, these three metals make up the most common materials found in jewellery. The main difference between these three metals is the fact that while Silver and Platinum are silvery white in colour, Gold is naturally yellow.


Gold is measured in Karats and while that sounds similar to how diamonds and gems are measured in carats, there is a big difference. Gold Karat is defined by how pure the gold is. This is a fraction out of 24 parts (also parts per thousand). In other words, pure gold, which is 100% natural gold (actually 99.999%) is considered to be 24 karat gold (24 parts gold out of 24 parts). While Diamonds, gemstones and other precious stones are measured with Carats, as in, Carat weight. This is the weight of the stone and although people commonly mistake it for the size, 1 Metric Carat is equal to 0.2 grams.

24 Karat Gold

Although 24 Karat Gold is Gold in its purest form, it is also very soft. Too soft, in fact, to be used in jewellery that is intended to be worn daily. Normally, the jewellery that is made with 24 Karat Gold is used for very special occasions or traditions. There are a lot of traditions around the world that do involve 24 Karat Gold jewellery, Chinese and Indians are known for giving 24 Karat Gold gifts during weddings and births. 24 Karat Gold jewellery 95% of the time will have a stamp on the inside of the item stating that it is 24kt. This stamp will look like “24K/24kt/999/99%

18 Karat Gold

18 Karat Gold is the purity that we here at Diamond Elite use the most. 18k Gold is 18 parts gold out of 24 parts or ¾ Gold. It is comprised of 75% pure Gold and we believe it is the most appropriate karat gold to be used in fine jewellery as it has enough purity to know you are indeed wearing Gold but not too pure which in turn makes it too soft. 18k Gold is durable enough to be worn daily  and usually stamped with “18K/18kt/750/75%”. The appearance of gold with higher karat will be more yellow, i.e. 18k Gold will appear more yellow than 9k Gold as the ratio of Pure Gold is higher in 18k Gold.

14 Karat Gold

14 Karat Gold is also a suitable option for high end jewellery that can retain its value and is also has moderate Pure Gold content to have a nice yellow colour. 14 Karat Gold is 14 parts Gold out of 24 parts, or in other words 58.3% Gold, while the rest is metal alloy. 14 Karat Gold is usually stamped with “14K/14kt/580

9 Karat Gold

9 Karat Gold is the lowest purity of Gold found in jewellery with 9 parts of Gold out of 24 parts, or 37.5% Gold. This Gold is usually found in low end jewellery and many marketplaces around the world. While many jewellers don’t like to work with 9 Karat Gold due to its low retail value and high labour costs, we will happily make you a ring in 9 Karat Gold should you so desire. 9K Gold will usually have a stamp indicating its purity like so “9K/9kt/375”.

If 14 Karat Gold is 58.3%, what is the other 41.7%?

Jewellery is actually made out of alloys. An alloy is a mixture of metals. In this case it is the mixture of Gold and another metal and this is what gives Gold its “purity”. In 18K Gold we mentioned the fact that it is 75% pure, the other 25% is another metal mixed in to give it a desired colour or to make the alloy and jewellery item as a whole a bit stronger. When you hear that 14K gold is 14 parts Gold out of 24 parts, the remaining parts (in this case 8 parts) is this mystery metal. This mystery metal is where the different Gold colours come into play.

Gold Colours

Gold comes in many different colours (even though it is naturally yellow) with the main three being: yellow, white, and rose. There are many more other colours out there, but they are nowhere near as common as the main three. These colours are obtained by using a certain metal to be mixed with the gold to create the alloy that is used for the ring or jewellery item. For example, in 18K Gold that is 75% pure Gold, the other 25% that is left is the metal that decides what colour the Gold will be.

In Yellow Gold we simply use copper and silver with a bit of green tint to maintain the natural yellow colour of the Gold. In White Gold, which is very popular these days, the Gold is mixed with silver and nickel to create the white colour, afterwards it is plated in Rhodium (another precious metal, even more expensive and rare than Gold or Platinum). And finally, in Rose Gold the remaining metal is simply copper, giving it the distinctive pink hue.


Platinum is another precious metal that is very commonly used in fine jewellery. It is rarer than gold and denser, therefore more is needed to create the same item, hence the added price. Platinum is generally 10-25% more expensive than its Gold counterpart. Since there are not that many different mixes of platinum we will only explain one. PT950 is the purity of Platinum that we use, and it is one of the finest purities available. This Platinum is at 95% purity, with the other 5% most commonly Ruthenium. Also, like white gold it is plated in Rhodium to give it an extra shiny white silvery finish. The main difference between white gold and Platinum is that Platinum does not tarnish. However, both White Gold & Platinum look exactly the same on the outside as both are plated in Rhodium. It is the Rhodium that gives White Gold & Platinum the bright white finish. In other words, White Gold rings over the years eventually will turn into a dull yellow colour, reverting back to its natural state. Platinum will always remain silvery, but it can become dull over time due to scratches and blemishes. PT950 Platinum normally has a stamp indicating its purity, for example “PT950/PLAT/P950”.

Which will last longer Platinum or White Gold?

Both have their pros and cons. While Platinum is less prone to bend, it is a softer metal and less resistant to scratches, unlike White Gold which scratches less. Platinum over time will become a dull silver, while White Gold will tarnish and start to yellow. At the end of the day the difference between White Gold and Platinum is more for your personal preference than for actual use. Since both are plated with rhodium, depending on the wear and how you treat them, in a few years down the line you will want to polish & rhodium plate you ring so that they look brand new. As jewellers we are obliged to tell our customers that jewellery will last as long as you take care of it. Jewellery should not be worn while doing the dishes, gardening, showering, exercising or anything that damages the ring in anyway. It could be these exact activities that make you want to take your ring in for rhodium polishing in 2 years, or 5.

Diamonds and Gems in our Wedding Bands

Diamonds and gemstones can be found in women’s wedding bands, but we also have a few men’s designs that include them. The diamonds that we use are completely natural and are not treated in any way. While most jewellers use low quality small diamonds because they are quite small and insignificant we prefer our diamonds to be of a certain standard as part of our quality control. Most small diamonds found in generic jewellery uses G/H coloured, SI clarity diamonds, however here at Diamond Elite we use F colour, VS clarity diamonds. Valuations can be provided at request to vouch for their quality. The gems that can be found in our wedding bands are also completely natural and never treated in any way, shape, or form.
