Diamonds are one of the most precious and prized gemstones found on Earth and have been valued and desired for thousands of years. They are formed billions of years ago and one hundred miles beneath the Earth’s surface from deep-source eruptions. When a deep-source volcanic eruptions occurs, magma from deep within the mantle shoots up and passes through a diamond startility zone on route to the surface. From there, pieces of rock from the diamond stability zone may be torn free and carried rapidly upwards to the surface. These pieces of rock are known as “xenoliths” and may contain diamonds

Diamonds are notoriously known for their immense hardness. In fact, the word diamond derives from the Greek word “adamas,” meaning invincible or indestructible. Due to their hardness, diamonds are 58 times harder than anything in nature and, as a result, can only be cut with another diamond. As a result of the hardness of diamonds, many ancient cultures believed that diamonds gave the wearer strength and courage during battle, and some kings wore diamonds on their armour as they rode into battle. Ancient Hindus also used diamonds in the eyes of devotional statues, and believed that a diamond could protect its wearer from danger.

Colour

Diamonds are made up of just one element, carbon, and in additional to the colourless diamond or white as some may know, diamonds come in a variety of colours: white, black, brown, yellow, blue, pink, green, purple, and red. Ironically while coloured diamonds (for example, blue, pink, yellow, etc) are highly demanded and prized, the presence of colour in a white diamond will lower the price. The less body color in a white diamond, the more true color it will reflect, and thus the greater its value.

With respect to coloured diamonds, the more saturated the color, the higher the value. In fact, diamonds sparkling with intense color are rare and may be priced higher than a colourless diamond of equal size. The unique physical properties of a diamond means it has the best possible luster of any gemstone when cut and polished well.

The colour of colourless diamonds and the colour of coloured diamonds are graded differently. Where colourless diamonds are graded on an alphabetical scale, coloured diamond are graded simply by faint-fancy, light-fancy, fancy, fancy-intense, vivid.
However, the clarity of all diamonds, regardless of colour, are graded on the same scale. See images of scales below. Completely colourless diamonds (such as D and E) are much rarer than others which is why they come with a higher pricing premium.

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.’ Diamond clarity is the quality of diamonds that relates to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects, called blemishes.

Most inclusions present in gem-quality diamonds do not affect the diamonds’ performance or structural integrity and are not visible to the naked eyes. However, large clouds can affect a diamond’s ability to transmit and scatter light. Large cracks close to or breaking the surface may reduce a diamond’s resistance to fracture.

Diamond clarity is the least important factor when choosing to buy a diamond because most diamonds have blemishes and small inclusions that are microscopic, unable to be seen with an untrained or unaided eye.

These tiny, natural blemishes and inclusions are microscopic and do not affect a diamond’s beauty in any way. Diamonds with the least and smallest inclusions receive the highest clarity grades.

CARAT

Diamond carat is often misunderstood and refers to a diamond’s weight, Measures a Diamond’s Apparent Size. Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams.
When comparing diamond carat sizes, take a diamond’s cut into consideration as well: a high- carat diamond with a poor cut grade may look smaller, often cut deeper, than a diamond with smaller carat weight and a better cut.

Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweler 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 4Cs: Clarity, Color, and Cut.

Some weights are considered “magic sizes” – half carat, three-quarter carat, and carat. Visually, there’s little difference between a 0.99 carat diamond and one that weighs a full carat. But the price differences between the two can be significant.

CUT

Often over looked, the diamond cut is the most important element to consider when buying a diamond. A diamond’s cut refers to its facets and angles; their number, proportions, and symmetry, which affect how light reflects out of the stone and created the sparkle and fire in the diamond. The cut of a diamond greatly affects a diamond’s brilliance; this means if it is cut poorly, it will be less luminous and contrary to popular belief, cut does not refer to the actual shape (e.g pear, oval, round), but the symmetry, proportioning and polish of a diamond.

The grade for a diamond’s cut ranges from excellent, reflecting as much light as possible, to poor, with much light lost out of the sides or bottom of the diamond. A skillfully cut diamond will reflect as much light as possible out of the table (top face) of the crystal and thus appear fiery and brilliant

While high grades of color or clarity affect a diamond, it’s the cut that determines its overall proportions and its ability to reflect light. This effect on brilliance has a direct effect on the value of a diamond, and is an important factor to consider when evaluating one for purchase.
