Everyone wants a sparkly ring with an even more sparkly diamond, its important when you purchase a ring that you purchase something that is unique and different and something that reflects you to give it the wow factor. Before you purchase a diamond ring it’s important to look at the Four C’s- Cut, Clarity, Colour and Carat to ensure your making the right decision.
Also, when purchasing a diamond over 1ct it’s important to see the certification of the diamond. This is an independent validation of the diamond for which you have paid for to ensure you have the diamond you have paid for. The main examining bodies are GIA, HRD, IGI, AGI. At Je t’aime we grade our diamonds and provide you with the certification to ensure the highest level of accuracy and guarantee for a high-quality diamond.
Diamonds are crystal structures formed over millions of years. The standard for grading and understanding a diamonds quality was founded by the GIA and used across the world. This allows customers to easily understand a diamonds quality and become fully informed of what they are about to buy. A diamonds 4C’s are their Colour, Clarity, Cut, and Carat. Continue reading, to find out more about each of the 4C’s.
A diamonds colour is based on the prescience or absence of a colour or hue. A perfect colourless diamond has no colour within the stone and is perfectly pure. Purer diamonds are rarer to come by and are therefore more costly to purchase- however maintain their high value.
Colour is graded from D-Z on the GIA colour scale. Most diamond colour variations are unnoticeable, however as you move down the colour scale the colour becomes more prominent within the diamond. In a diamonds colour, such slight variations have a significant impact on the price and valuation of the diamond. To understand more about colour scales please read our colour chart displayed below:
Colour D-F colourless diamonds with D being the most colourless with no sign of colour to the naked eye.
Colour G-J is near colourless diamonds where there is a slight hue detected within the diamond which is unlikely to be totally visible to the naked untrained eye.
Colour K-M are where the diamond has a faint colour detected hardly visible to the naked eye.
Colour N-R is where the diamond has a very light colour- slightly visible to the naked eye.
Colour S-Z is when the diamond in question has a light colour which is totally visible to the eye.
To see each colour graphically and what they mean and look like, please see the GIA Colour Chart below.
Clarity, this refers to either the presence or absence of inclusions and blemishes located within and on the diamond.
Diamonds form from carbon structures deep underground over millions of years exposed to high temperatures and pressure. This formation process can therefore create a range of internal characteristics for each diamond- known as inclusions and exterior characteristics known as blemishes. Whist its very rare to come across a perfect diamond, the closer the clarity is to perfection the higher the value and price.
The GIA has six categories for grading a diamonds clarity and they are the following:
Flawless (FL): This means there is no inclusions and blemishes under 10x magnification.
Internally Flawless (IF): This means there is no inclusions under a 10x magnification.
Very Very Slightly Included (VVS1 and VVS2): Inclusions are observed under 10x magnification but are so slight they are even difficult for a skilled grader to identify.
Very Slightly Included (VS1 and VS2): Inclusions are observed under 10x magnification but are only minor.
Slightly Included (SI1 and S12): This means inclusions are noticeable under 10x magnification.
Included (I1, I2, I3): Here inclusions within the diamond are obvious under 10x magnification affecting the diamonds brilliance and transparency.
Many inclusions and blemishes are unnoticeable to an untrained eye- for example, VS1 and SI2 look exactly the same to the naked eye but in terms of internal quality are vastly different. To view graphically see a diamonds inclusion in terms of clarity, please see the GIA Clarity Chart below.
A diamond cut gives it the ability to reflect light to ensure it sparkles and shines in different ways and intensities. Precise workmanship is needed in order to make a diamond shine intensely- so its proportions, symmetry and polish are vital to that immense shine only found in diamonds.
Many refer a diamond cut as the actual shape of the diamond such as round, oval, emerald, baguette, marquise, pear and so on- However the cut of a diamond is about how the diamond in question reacts to light that shine upon it.
Each diamond’s cut is rated by the GIA as one of the following- Excellent, Very Good, Good, Fair and Poor. Excellent is the most expensive and highest rated diamond cut. A diamonds cut is vital to a stone’s beauty and the most difficult part of the diamond to analyse.
Proportions of a diamond’s facets help influence how successful each diamond is when it interacts with light rays to create a desirable outcome such as brightness, fire and scintillation. Brightness is the internal and external white light that is reflected from the diamond. Fire, is the scattering of the white light rays that are transferred into colours of the rainbow and scintillation, refers to the amount of sparkle a diamond creates, and the pattern of light and dark areas created by the diamond’s internal reflections.
Each diamond is different and unique, each producing differing results when they interact with light rays. This gives each diamond an individual and unique characteristic on its ability to influence light to create visually stunning effects.
A diamonds carat weight measures its visual size and its weight. One metric carat is equivalent to 200 milligrams, to ensure a diamonds weight is precise, each carat is subdivided into 100 points allowing precise measurements to the hundredth decimal place. Jewellers therefore can grade carat weight below 1ct as pointers, e.g., 0.75cts can also be referred to as 75 points. Diamonds above 1ct are expressed in carats and decimals- e.g., 1.75ct.
Ceteris Paribus, diamond prices increase with carat weight as larger whole diamonds are much rarer and desirable to come across. However, although two diamonds may be the same weight, they can differ vastly in price based on their individual colour clarity and cut.
A diamonds value and price take into account all of the 4C’s- Colour, Clarity, Cut and Carat weight.
