Carat. The size of your carbon footprint.

Swiss

Last and the easiest of the 4 Cs to see, the Carat measures the weight of a diamond. Want to know why diamonds are so valuable? Because it takes 250 tons of rock to produce just 1.00ct.

Carat. Not karat.

First point to note: carat has absolutely nothing to do with karat, which is a measure of gold purity. The term comes from the Greek for “fruit of the carob tree” (Wikipedia). The seeds of the carob pod were almost always identical in weight – and a natural standard of measurement.

Today, the metric carat weighs 200 milligrams (0.2 grams) and has become universally accepted. For absolute precision, carats are subdivided into 100 points. So a diamond weighing 0.50 carats, for example, is referred to as a ‘fifty pointer.’

 

Carat pricing

A diamond cutter’s highest priority is to maximise the carat weight of a diamond. The larger the diamond, the rarer and more expensive it will be, with prices increasing exponentially as the diamond carat weight increases.

Critical carat weights are: 0.30ct, 0.40ct, 0.50ct, 0.70ct, 0.90ct 1.00ct, 1.50ct, 2.00ct, 3.00ct, 4.00ct, 5.00ct, 10.00ct.

 

The perfect diamond is a balancing act

When shopping for a diamond, and assuming you have a budget, you’ll tend to balance the carat on one side against the other three Cs on the other. So as you go up in weight, you may have to dial down one or more of the colour, clarity, or cut.

 

But how much does the weight of your diamond really matter?

So yes, the weight is important because it has such an influence on the price. But it isn’t as important as you might think. Because when a diamond is set in jewellery, your eye is drawn more to the size – and to the sparkle of course.

In fact, people really only see the surface and not the weight or total size.

Montluc says – Don’t invest in the biggest diamond but in the best!

That’s where Montluc comes into its own.

Montluc jewellery is specifically designed and beautifully crafted to expose the maximum possible surface area of the diamond. Which means you show more… sparkle more… without having to pay more. » Check out our approach to pricing to see how we offer such stunning value.

 

Cut before carat

The cut is the one C that brings a great diamond into its own – and the secret behind the sparkle. The quality and skill of the cut ranges from Poor to Excellent on official Gemological Institute of America (GIA) gradings.

Diamonds that are cut very well will also tend to have less depth and more spread, which has the effect of making them look visually larger than their carat weight would suggest.

Excellent is the highest grade and is met only by the the top 3% of the world’s diamonds.

Montluc is extremely rare in only ever using a standard of quality that goes two steps further.

Our Triple Excellent cut is the best there is, guaranteeing that every diamond is impeccably polished and aligned as well as perfectly cut.

After all, why invest in the biggest diamond you can…when you can go for the best?
