What does this mean?

 

GIA, or the Gemological Institute of America, is THE training authority in the jewelry industry. To become an applied jewellery professional. from the GIA, you must complete and pass three course studies, and then pass a comprehensive final exam. While you do earn a certificate of completion after each class or lab, you must complete and pass all three to earn the degree of applied Jewellery proffesional.

Below we will go through the 4'cs of diamonds that are essential to know about when purchasing a diamond, the team at Martin & Martin hand select every diamond we use in the  jewellery made in our workshop to ensure you are getting the absolute best stone available for you to suit your budget or requirement, we are always available to discuss these with you and go through your needs,and the best thing about this is we are always willing and able to get a selection of diamonds in for you to see yourself and select the perfect diamond for you at no obligation .

There is much more to diamonds than just the 4'cs, sure they are important in finding you the right stone but there are so many other factors we take into consideration when selecting stones, things like Polish,Symmetry,Cut, Depth,Table & Fluorescence to name a few, we see a lot of people that have bought diamonds from websites online because the price was too good, there will always be a reason why the the stone is that well priced and a vast majority of the time they do not end up with exactly what they though they would.

If you are keen to spend the time and research the other factors we have listed we always advise too, we are more than happy to go through them with you in-store or even if you contact us via email or phone we can help guide you on what will be best for you 

Colour

The diamond colour evaluation of most gem-quality diamonds is based on the absence of colour. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA’s D-to-Z 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.

Clarity

Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. 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. While no diamond is perfectly pure, the closer it comes, the higher its value.

The GIA Diamond Clarity Scale has 6 categories, some of which are divided, for a total of 11 specific grades.

Flawless (FL) No inclusions and no blemishes visible under 10x magnification

Internally Flawless (IF) No inclusions visible under 10x magnification

Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification

Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification, but can be characterized as minor

Slightly Included (SI1 and SI2) Inclusions are noticeable under 10x magnification

Included (I1, I2, and I3) Inclusions are obvious under 10x magnification which may affect transparency and brilliance

Cut

Diamonds are either cut where every facet is a triangle or a straight line, but the term cut here actually refers to the shape of the diamond. Over the years certain shapes have become the accepted norm, as pictured below.

A round diamond (often referred to as a Brilliant cut) is timeless and the shape most associated with an engagement ring. It is, therefore, the safest choice if you are unsure which to buy.

Carat

Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams.

Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweller may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweller may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’

All else being equal, diamond price increases with diamond carat weight because larger diamonds are more rare and more desirable. But two diamonds of equal carat weight can have very different values (and prices) depending on three other factors of the diamond 4CsClarityColor, and Cut.

It’s important to remember that a diamond’s value is determined using all of the 4Cs, not just carat weight.
