Our Diamonds

The cut refers to how a diamond has been shaped and faceted, which directly impacts its sparkle, brilliance, and overall beauty. A well-cut diamond allows light to enter, reflect off its facets, and exit through the crown, creating the captivating play of light and sparkle that diamonds are known for.

When talking about cut, we typically think of shape (such as round, oval, emerald, princess, pear and cushion) but the cut of a diamond actually refers to its facets. It’s how the light interacts with these facets that distinguishes a higher-quality of diamond. Skilled workmanship and laser cutting along with symmetry and polish, delivers the maximum return of light, completely unique to diamonds.

Some terms you may come across when referencing the cut of a diamond are:
Brightness: The internal and external white light that reflects from a diamond
Fire: The scattering of white light to produce a rainbow of colours
Scintillation: The amount of sparkle a diamond has, and the combination of light and dark areas caused by reflections within the stone.

Interestingly, in terms of the 4Cs relating to a white diamond, colour actually refers to the lack of colour. Diamond colour is evaluated based on how colourless or how much colour is present within the stone. The GIA grades colour on a scale from D to Z to distinguish quality. D is the highest grade and represents a completely colourless diamond and Z indicates a noticeable tinge of light yellow to brown shades. Special lighting specific to diamonds helps professionals view the colour of diamonds accurately.

While the diamond colour scale provides an example of how each grade appears, factors including cut, carat weight and shape, may impact how colour appears differently among different diamonds.

It is also worth noting that typically, the naked eye cannot tell the difference between two adjacent colour-graded diamonds, though this may be significantly reflected in the price between the two stones. It is worth checking the opinion of the gemologist in your appointment to ensure that you get the best-suited diamond for you.

A diamond's clarity refers to how ‘clean’ a diamond is. Formed from carbon through intense heat and pressure, it is natural for diamonds to include internal blemishes and inclusions, as this is part of their makeup. However included diamonds tend not to be as sought after due to their sometimes visible imperfections. The GIA’s clarity scale helps determine the value and quality of a diamond through its level of inclusions and blemishes.

The term “eye-clean” is often used when discussing diamond clarity. This refers to inclusions or internal blemishes that may be visible only under magnification, and not to the unaided eye. It can occur that two diamonds of the same clarity grade may appear slightly different as one may be eye clean and the other not, depending on where the inclusions are placed inside the stone.

The scale of clarity is categorised by:

Flawless (FL): no inclusions or 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 professional to see under 10x magnification.

Very Slightly Included (VS1 and VS2): inclusions are observed with effort under 10x magnification but are minor.

Slightly Included (SI1 and SI2): inclusions are noticeable under 10x magnification.

Included (I1, I2, and I3): inclusions are obvious under 10x magnification which can affect the transparency and brilliance of the diamond.

The final of the 4Cs; carat weight is what most people associate with when referencing diamonds. The carat weight measures how much a diamond weighs. This is the most accurate gauge for measuring diamonds as two one-carat diamonds may differ in size depending on the shape of the diamonds and how they are cut.

One carat is defined as 200 milligrams, with each carat divided into 100 points, allowing for precise measurements to a hundredth decimal place, so one-carat measures 0.2 grams. The term carat is derived from the carob seed, which measures the same 200 milligrams, this seed was used as it was seen as a reliably consistent weight. Using carats as a measuring tool was standardised in 1907, creating a universal system to prevent any varying carat weights.

They each impact the environment in different ways. Naturally mined diamonds are a natural resource and therefore found in diamond mines or alluvial deposits (e.g. riverbeds). If mined responsibly, the impact to the surrounding environment is controlled and many communities will nurture the local environment, for example by re-planting trees. Furthermore, diamond mines can create local beneficiation. Solar Diamonds are lab-grown and therefore require energy for production. At Fenton, we do this using renewable solar power so as to limit the environmental impact as much as possible and reduce the reliance on natural diamonds where possible. Other types of lab grown diamonds are created without the use of renewable energy (e.g. fossil fuels) and can therefore be detrimental to the environment. At Fenton, we are always trying to ensure we make the right decisions for the betterment of the industry and its people, the environment, and for our customer.

As a brand that offers responsibly-sourced gemstones, we have been searching for the best way forward to offer naturally mined diamonds that reflect our brand values, which we have now found. We will continue our efforts to source responsibly as we feel it to be an incredibly important aspect of the industry we are in.

Solar Diamonds are created in a lab using solar power, and are therefore not reliant on the geology of naturally mined diamonds, nor the immense expense of natural mining, cutting and import / export. These factors all contribute to the price difference between the two gemstones. The price difference is not to do with the quality or stability of the two types of diamond, which are both chemically identical.
