What Does the Carat Weight Say About the Diamond?

To start,what does carat mean? Carat is the unit of measurement used to specify the weight of precious stones. Although a carat was only officially equated to a weight of 200 milligrams in 1907, the unit of measurement was used before that.

The word derives from 'keration', an Ancient Greek term for the pod of the Carob tree. The Ancient Greeks grasped that this pod had a relatively constant weight and as such was ideally suited for precision measurements. With that said, be sure not to confuse this with the gold karat. Gold karat indicates the clarity of the precious metal, rather than its weight.

The carat measurement refers to the weight and size of the cut diamond. In fact, the most carats a diamond has ever had is the 3106-carat Cullinan Diamond.

To determine how many carats the diamond in her engagement ring should be, we fundamentally go with your personal preference, as well as your budget. Or would you rather take the average as a guideline?

How Many Carats Does the Average Diamond Engagement Ring Have?

Looking at the global market, we can see that the average carat weight for an engagement ring lies around 1.00 to 1.09-carats. A stone of comparable carat weight glimmers in approximately 19% of all engagement rings sold.

In line with this guideline, how much might your loved one’s engagement ring cost? For a 1.00-carat diamond, you will pay around €3,900 to €4,500. However, for an exceptionally qualitative diamond of the same carat weight, the price can run up to €12,000. These prices are indicative only, given that at BAUNAT, we adjust our prices on a weekly basis to reflect market changes.

Tip: take a look at the diamonds with a carat weight just under the rounded figures. So, for example, if you are looking for a 1.00-carat diamond, also take a look at a stone of roughly 0.90-carat. Doing so will save you up to 25%!

Look at Other Elements of An Engagement Ring

It may surprise you to know the weight of the diamond in an engagement ring is actually the least important factor. Higher quality is better than higher carat weight. When determining how many carats your diamond engagement ring should be it is also important to consider the cut, clarity and colour of the diamond.

A smaller diamond with a better cut will sparkle beautifully and appear larger than it actually is. And that is not the only tip in having a diamond look bigger than it actually is. When choosing the right diamonds, consider the 4Cs: cut, colour, clarity, and carats. Together, these details are indispensable in your engagement ring quest.
Given the market is in a constant state of flux, there is no fixed price for a 1-carat diamond. This is why we adjust our prices at BAUNAT every week to reflect market dynamics, ensuring you always get the most fair price.

How To Pay Less For the Same Amount of Diamond Carats in Your Engagement Ring?

You can also spread the total carat weight over several smaller diamonds. Engagement rings with two diamonds and even trilogy engagement rings with 3 diamonds are hugely popular at the moment. The more stones, the greater the brilliance and the bigger the diamonds will appear.

Which Other Precious Stones Can You Add to a Diamond Engagement Ring?

Diamonds may perhaps be the most valuable precious stone, but it is not the only one deserving of that name. Sapphire, emerald and ruby are similarly described by carat weight and are also exceptionally valuable.

Blue sapphire, green emerald and red ruby are cheaper than diamond by carat but they are still very rare and as such extremely valuable. Do you want to have more carats in your engagement ring but also attain a more unique appearance? If so, opt for a coloured precious stone as the central stone in your engagement ring.

What About Precious Metal Carats?

As previously mentioned, the value of the precious metal is also expressed in karats. So, you may also want to consider the karats of the precious metal in your engagement ring as well. While diamond carats indicates the weight of the stone per 0.2 grams, in precious metals, karats indicate the mixed-metal content in the alloy.

What Does Alloy Carat Actually Mean?

For an 18-karat gold ring , we use 75% pure gold and 25% silver, copper or palladium. 18-karat gold is the optimum jewellery content. Less than 18 renders the ring pieces less valuable, but pure gold is very soft and fragile. So more than 18-carat gold will make your ring less robust and too delicate for long-term wear.

What About Platinum?

Platinum is an entirely different type of precious metal. Because of the metal's inherent durability, a platinum alloy is not recommended. That durability also makes the platinum more difficult to manipulate, so it is usually more expensive than red, yellow or white gold.

Platinum vs. White Gold

Because of its silver-grey colour, platinum is often confused with white gold, but there are still differences in the colour. i Platinum is more grey, whereas white gold is a glossy white. This gives platinum a sleeker, modern appearance, whilst white gold is more of an elegant, classic choice.

Frequently asked Questions

The Difference between A White Gold and Platinum Engagement Ring


White gold and platinum look very similar at first, but they actually differ in many aspects. To tell them apart you should use the five C's: Composition, Colour, Cost, Care and Culture.

Do you prefer platinum or white gold for your diamond engagement ring? Get to know the difference between the two precious metals here.

1st C: Composition

How does the composition of white gold differ from platinum?

Most white gold diamond jewellery is offered in 18 karat, which consists of 75% pure gold and 25% other metals, necessary for colour and strength. To achieve the white colour, pure gold (which is naturally yellow r) is mixed with additives such as silver and palladium. At the end, white gold jewellery gets rhodium plated, which gives the jewel its bright white colour.

 Pure gold is too pliable and therefore not suitable for jewellery. That's why  we use gold alloy, a combination of gold and other metals.

Platinum jewellery on the other hand, consists of almost pure platinum. It is usually made using 95% pure platinum in combination with 5% other metals, making it softer, more scratch-resistant, and more likely to bend than break. Because of its density, jewellery in platinum weighs around 34% more than gold jewellery. So, if you seek large earrings, we recommend going for white gold as heavy earrings might feel uncomfortable.

In terms of allergies, it’s a tie. Even though platinum is known to be both hypoallergenic and durable, European guidelines ensure that 18 carat jewellery may only contain a minimal amount of nickel, which makes white gold an excellent hypoallergenic alternative to platinum.

At BAUNAT, we go one step further. By composing all of our white gold jewellery with palladium instead of nickel, the jewellery retains its white colour longer and is an excellent choice for those with nickel allergies or sensitive skin.

2nd C: Colour

What colour does white gold and platinum have?

At first glance, jewellery in white gold and platinum seems to have the same colour, but when you look closely, there’s a visible difference.. You can recognise an  engagement ring in white through its  pronounced silver sparkle, while the colour of platinum tends to lean more to a grey colour.

Due to the colour difference between platinum and white gold, experts don’t recommend a combination of these two precious metals. If your partner chooses a platinum engagement ring, then also go for a platinum wedding ring.

3rd C: Cost

What is the price difference between a white gold and a platinum ring?

Platinum jewellery is usually more expensive than white gold and there are several reasons for this. Although pure gold is more expensive than pure platinum, less gold is needed to make the same jewel. Not only because of platinum’s high density, but also because the alloy contains 95% pure platinum whereas white gold only contains 75% pure gold.

Another difference is that platinum is much rarer. Each year, fewer platinum ore is mined than gold ore. It concerns just under 200 tonnes compared to 1500 tonnes of gold ore respectively.

 Platinum in its pure form is much stronger than pure gold, but when both precious metals are used in an alloy, 950 platinum becomes softer, making it harder to work with and increasing the labour cost of the jewel.

If you decide against buying platinum, but rather white gold, you can invest the money you saved in a larger diamond for your engagement ring. Of course, it comes down to your personal choice.

4th C: Care

How to maintain your gold or platinum jewellery?

Given that white gold jewellery consists of 75% pure gold and thus yellow components, it can show a yellowish undertone after a few years, when the rhodium wears off. Fortunately, it is relatively easy and inexpensive to have your jewel rhodium plated again. Depending on the usage of the jewel, a rhodium dip can stay perfect for a few years or even decades and will mainly wear at the bottom of the ring. A platinum ring on the other hand retains its white grey colour for life.

In terms of wear, both metals scratch differently. Since 18 carat gold is harder than platinum, it is more likely to lose a little of its metal when scratched. Meanwhile, a scratch in platinum actually displaces the metal, leaving ridges on the edges of the scratch.

Last but not least,white gold jewellery can more easily be adjusted in size and the adaption is less visible. Due to the specific properties of platinum, you will most likely be able to see a line at the joint, even when the resizing was done properly because the soldering is of different alloy.Cleaning white gold or platinum jewellery yourself is easier than you think. Even for jewellery with diamonds, you have the right cleaning agents at home.

We do recommend that you clean platinum and gold jewellery yourself on a regular basis. You can easily do this by soaking the jewellery in a mixture of lukewarm water and detergent. In time, it is recommended to have your platinum and white gold jewellery cleaned professionally by a jeweller.

5th C: Culture

What is the symbolism of platinum and white gold?

Gold has been the most traditional precious metal for engagement and wedding rings for years and symbolises eternal love and dedication between partners. Gold is also often associated with royalty and divinity. Yet platinum seems gradually to become the new symbol of prestige and wealth. Many artists have already been awarded a platinum record, and anyone with a platinum credit card enjoys more privileges and benefits than the holder of a gold credit card. So, the tides have begun to turn. 

Platinum is also associated with patience, determination and perseverance in popular culture. Whether you choose rings in platinum or white gold, the symbolic value is assured.

What is carat?

Carat is the term used to describe the purity of gold and the weight of the diamond. Are you going to buy a gold piece of jewellery with a diamond? Completely pure gold is 24 carat and not strong enough for jewellery. Your jewellery must be a minimum of 14 carat to count as gold. A diamond’s carat is 0.2 grams.

Learn more about the diamond’s carat and gold carat or ask BAUNAT’s diamond experts for advice.

What is a hallmark?

A hallmark, or jewellery stamp, protects you against fraud, and protects merchants against unfair competition. Gold and silver have been mixed with other metals for centuries, as they are much too soft in their original form to make jewellery. It is not possible to recognize at a glance the quantity of cheaper metals used during manufacture. A layer of gold of a couple of microns can seem like real gold when still new. Most competent jewellers and chemists also cannot tell how much of the noble metal is present in an alloy.

Because of the high price of noble metals, some dishonest merchants are tempted to use less valuable alloys. This fraud is difficult to detect, and honest merchants and clients are duped.

There has always been a need to protect the public and suppliers. This is why all objects sold as gold, silver or platinum should be stamped with a hallmark to confirm that they comply with legal norms. That way you can e.g. see what the gold percentage of your white gold jewellery is by looking at the hallmark.
