The 4Cs of diamond

At RÊVER we create jewelry to last for a lifetime, pieces ready to elevate any look without following any trends. All our jewelry is set with lab grown diamonds by the best artisans, they are the ones that make it possible.

We want to let you know the features of this precious gemstone and give you the keys so you can choose your perfect one.

Universally known as the 4Cs of diamond, Colour, Clarity, Cut and Carat Weight are the universal standards for evaluate the quality of any type of diamond. They are used to evaluate all diamonds, the ones created in a laboratory, and those extracted from the mines. Below, we explain more details about each feature.

 

Colour

The colour evaluation of most gem-quality diamonds is based on the absence of colour. A chemically pure and structurally perfect diamond has no hue and consequently, a higher value. For this reason, the diamond colour-grading system measures the degree of colourlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones of established colour value.

Many of these diamond colour distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.

We work with diamonds from D to H colour.

 

Clarity

To understand this concept, we need first know how diamonds are created. Lab grown diamonds are the result of replicate the conditions that naturally exist between 140km and 190km below the surface with a unique combination of high pressure (up to 60,000 ATM) and high temperature (up to 2,500º C). This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’

Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. If you are trying to determine what is the best clarity for a diamond, remember that no diamond is perfectly pure. But the closer it comes to purity, the better its clarity.

We work with diamonds from I.F. to SI1 clarity.

 

Cut

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape (round, heart, oval, marquise, pear), but what diamond cut actually does mean how well a diamond’s facets interact with light.

We want to let you know that this is the most complex and technically difficult to analyze. The cut is the only one of the 4C that determines the man and requires a lot of artistry and workmanship to fashion a stone.

Carat weight

Diamond carat weight measures how much a diamond weighs. So, a metric “carat” is defined as 200 milligrams and each carat is subdivided into 100 points.

All else being equal, diamond price increases with diamond carat weight because larger diamonds are rarer and more desirable. However, two diamonds of equal carat weight can have very different values depending on three other factors of the diamond 4Cs: colour, clarity and cut.
