What Does the Carat Weight Say About the Diamond?

Let us start at the beginning: 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. After all, 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.  The most carats a diamond has ever had is the 3106-carat Cullinan Diamond. Don't confuse this with gold karat, however. Gold karat indicates the clarity of the precious metal, not its weight.

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 Diamond Carats Is the Average Engagement Ring?

Looking at the global market, we can see that the average carat weight for an engagement ring lies around the 1.00 to 1.09-carat mark. A stone of comparable carat weight glimmers in approximately 19% of all engagement rings sold. How much will her engagement ring cost in line with this guideline? 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 we adjust our prices on a weekly basis to reflect market changes.

Tip: take a look too 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. This will soon save you up to 25%!

Look At How Many Diamond Carats Your Engagement Ring Has

It may surprise you to know the weight of the diamond carats in her 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 will therefore look bigger than it actually is. And that is not the only tip in having a diamond look bigger than it actually is. We call all the key aspects to take into account the 4 Cs. They 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 to see the correct amounts.

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 I Incorporate in Her Diamond Engagement Ring?

Diamond might 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 carats so when how many carats is good for your engagement ring, you need to consider the precious metal, too. Where diamond carat indicates the weight of the stone per 0.2 grams, with the precious metal it indicates the precious metal content in the alloy. So, for the ring alloy jewellers combine gold with various types of precious metal.

What Does Alloy Carat Actually Mean?

For an 18-carat gold ring, we use for example 75% pure gold and 25% silver, copper or palladium. 18-carat 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 ringless robust and hard-wearing.

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 it is precisely in the colour that the difference lies. Platinum is more grey, whereas white gold is more glossy white. This gives platinum a sleeker, modern appearance, whilst white gold is more of an elegant, classic choice.
