A diamond is a hard and rare mineral. The high pressure and temperature make the diamond especially beautiful, transparent, and shiny. Pieces suitable for cutting are rare in nature, despite the fact that the mineral itself is quite common.
Interestingly, out of the 20% of the production of natural diamonds suitable for jewelry, only 40% are diamonds of one-carat weight or more, and only 50% of them are high-end luxury diamonds. They have been created inside the earth for millions of years, and most of the diamonds known today were thrown to the surface thousands of years ago.
Four characteristics describe the beauty and quality of a natural diamond: colour, clarity, cut, and carat size. They are all regulated by certificates from various laboratories. The best-known are those of the GIA (Gemological Institute of America), HRD (Hoge Raad voor Diamant), and IGI (International Gemological Institute).
Here at Luxury Diamonds, we have a vast selection of all types of not only natural diamonds but lab-grown ones as well. However, if you are looking for a GIA natural diamond, you have come to the right place. Here we will find a perfect stone for you, whether it is a classic clear diamond or a coloured one.
The History of Natural Diamonds
Diamonds are known for their hardness, not strength: a diamond can only be scratched with a diamond, but it can also be burned or broken. That is why the stone could not be cut for a long time.
Indian jewelers, who mined stones in the mines of Golconda, discovered the technology of cutting diamonds only in the 15th century. They crushed the small diamonds into powder and then inflicted it on a rotating grinding disk, creating diamond crystals with facets that allowed the light to refract.
Over five centuries, the diamond has established itself as the most expensive and desirable stone for jewelry. Since the nineteenth century, it has been the most popular stone for engagement and wedding rings.
The natural diamond’s price can change as it goes through different stages of sales. Before a diamond goes to a jeweler, it changes hands several times. The first transaction occurs between brokers at the exchange, and then the stones find their way to the dealers and jewelers.
Natural Coloured Diamonds
Some diamonds are valued for being colourless, and most of them are on the market. But diamonds come in all colours of the rainbow. Natural coloured diamonds are formed either by changes in the crystal lattice, natural radiation, or traces of mineral impurities in the stone during its formation.
For example, natural pink diamonds are created due to manganese, natural blue diamonds have their colour due to aluminum traces, and the brown (also known as cognac or chocolate) shade is due to iron. Among coloured natural rough diamonds, yellow is the most common colour, while blue, red, and green diamonds are very rare.
The rarest type of diamond is an untreated black diamond – a truly unique and beautiful gem. Natural black diamonds are given their colour by graphite and iron. The cost of black diamonds is lower, but the jewelry with them is considered exclusive. Black diamonds entered the jewelry fashion only a few decades ago at the hands of Italian Fawaz Gruosi, the founder of de Grisogono.
In addition to the rarity of natural coloured diamonds, their main feature is that only a few examples are of impeccable quality and can be used for gem cutting. Due to the complexity of the colouring process in the depths of the earth, many different flaws such as cracks, coatings, and haze occur in coloured diamonds, making them unsuitable for jewelry cutting. In the end, only a tiny portion of gems find their way to the jewelry market and later become part of fine natural diamonds for sale.
Diamonds’ colours according to GIA
The GIA International System describes the highest colour with the Latin letter D, and then the colours E, F, G, H, I, J, K, etc., follow in descending order. Here everything is simple: D-E-F - the highest group of colours is called “colourless.” They differ only by a slight hue, which an expert can see by turning a diamond upside down. This group belongs to the scarce and investment diamonds. These diamonds are supplied only for custom-made jewelry.
Diamonds of the G-H group are called “almost colourless” because they have a slight yellowish hue, which can be seen when comparing D and H colour diamonds. For this reason, G and H-colour diamonds are the most sought-after jewelry because they look no less spectacular than D-colour diamonds and cost several times less.
Fancy-shaped diamonds will have a more noticeable hue compared to round diamonds. The larger the diamond, the more evident its shade will be. To evaluate a diamond accurately, be sure to check its colour on the GIA International Diamond Scale. Here at Luxury Diamond, we filter our collection of natural diamonds not only by carat and cut but also by colour, making it easier for you to choose.
