1) CUT: THE SHAPE
Round Brilliant Cut Diamonds
Many consider the round-shaped diamond as the ultimate gemstone for jewellery pieces. These most popular diamonds are shaped in a circular outline and have a cone-shaped pavilion with 57/58 facets. Because these diamonds are highly sought after and due to the loss of rough stone during the cutting process, brilliant diamonds are pricier than their fancy-shaped counterparts.
Hearts and Arrows Diamonds
When cut to ideal parameters, every round cut diamond will display a perfect pattern of eight arrows when face up, and when viewed table down (pavilion), eight hearts will be seen. These patterns are seen only in round or cushion cut diamonds when cut using a combination of expertise and state-of-the-art technology.
Although a round diamond is regarded as the stone offering the most brilliance, we also offer fancy shaped diamonds. Beautifully crafted in different shapes and forms, a skilled diamond cutter can enhance the natural brilliance of any shaped stone.
Marquise Brilliant Cut Diamonds
A marquise diamond maximizes carat weight, which gives an illusion of a larger stone. Its unusual beauty is magnified when set with pear or round side stones. According to romantic fable, the first Marquise diamond was requested by Louis XV to mimic the shape of the mouth of his chief mistress, Marquise de Pompadour.
Pear Brilliant Cut Diamonds
Elongated pear shaped diamonds flatter hands with shorter finger length and creates a slimming effect. The droplet-style shape of these stones make them perfect for pendants and earrings.
Princess Cut Diamonds
The princess shape is a very popular choice for engagement rings. These stones can be cut to cater to your taste of a more square or rectangular shape, and are especially flattering on long, slender fingers.
Heart Brilliant Cut Diamonds
The ultimate symbol of love…what more is there to say about a heart-shaped diamond?
Trilliant Brilliant Cut Diamonds
These triangular stones, with either sharp or rounded corners, were popularised by Amsterdam’s Asssher family in 1962. An unusual shape, a trilliant-cut diamond resembles the brilliance of a flame.
Oval Brilliant Cut Diamonds
Oval-shaped diamonds are, like round diamonds, perfectly balanced and symmetric. They particularly flatter smaller hands and create an illusion of longer fingers.
Emerald Cut Diamonds
The stylish and elegant emerald diamond suit most hand types and are popular due to their price when compared to round diamonds. Emerald-shaped diamonds sit comfortably in all jewellery pieces.
The Quality of the Cut
A well-cut diamond is vital because it can transform your stone into an exquisite piece which is unique. Cut not only decides the shape and symmetry of a diamond, but also maximises the fire and brilliance of a diamond in the light. Cut also refers to the proportion and finish of a diamond.
Excellent: includes the Ideal cut reflecting nearly all the light back to your eye
Very Good: With minor deviations from excellent, giving great proportion and performance with less cost
Good Cut: Good performance for the budget
Fair Cut: Quality cut that falls outside of the good proportion limits. Recommended only as a budget option
2) CARAT: THE WEIGHT
Diamonds are weighed in carats. 1 carat equals 100 points, or 0.2 grams. Although a diamond’s weight is measured in carats, this is not necessarily indicative of the size of the stone. The reason for this is that the way a diamond is cut and proportioned can alter the perception of a diamond’s size – a badly cut diamond may be heavier in the girdle or pavilion which will increase carat weight although will appear smaller within a setting, whereas a well cut diamond will reflect light back to the eye, creating an an illusion of a larger stone.
Selecting the Correct Carat Weight usually depends on a combination of the following three factors:
- The size of her finger. Small fingers accentuate a diamond, which will make a larger diamond look even bigger.
If you have already selected a setting for a ring, you may have limitations on diamonds which will fit and suit that particular setting. We can help make your selection easy.
If you’re on a strict budget but carat weight is important, consider a well cut stone in a colour around J.
Clarity is graded according to the following scale:
SI2 Small inclusions but more than SI1.I1
IF Internally Flawless. No internal imperfections. Very rare.
VVS1 Very very small inclusions. Very difficult to see the imperfections even under 10 times magnification.
VVS2 Very very small inclusions, but more than VVS1
VS1 Very small inclusions. Inclusions are still not visible to the naked eye.
VS2 Very small inclusions, but more than VS1
SI1 Small inclusions. The imperfections are visible under 10 times magnification, potentially visible to the naked eye.
Internal inclusions that are hard, but not impossible to see with just the naked eye.I2
Inclusions are easy to see with the naked eye, and have some effect on the brilliance of the diamond.P3
Large inclusions that are clearly visible to the naked eye and have a definite effect on the brilliance of the diamond and
therefore on the overall value of the diamond. Needless to say, none of the diamonds in our collection fall in this grade
4) THE COLOUR
Diamonds are graded from D to Z; D being colourless. The less colour a diamond has, the more rare and valuable it is. Colour is visible to the eye. Diamonds graded D through to J will not show colour to the naked eye. When set in white metals, diamonds graded K and lower will start to show yellow tones.
Fancy Colour Diamonds
It is the richness of the colour of a fancy coloured diamond which increases the value of the stone. These incredibly rare diamonds (1 in 10,000) naturally possess a colour. When grading fancy coloured diamonds, the scale is as follows:
- Very light
- Light, fancy light
- Fancy intense
- Fancy vivid
- Fancy dark
- Fancy deep
The next most important characteristic of a fancy coloured diamond is the carat weight. Due to their rarity, it follows that the larger a fancy coloured diamond weighs, the greater the value.
Clarity is not as important in a fancy coloured diamond, because they are not colourless. However, it is essential that your diamond is authentic and not simply artificially coloured. Fancy diamonds are cut to enhance their colour. Often fancy coloured diamonds are cut in non-traditional shapes in order to emphasise their incredible colours.
If you don’t know a huge amount about how diamonds are priced and set, making your first purchase can be a baffling exercise.
When buying diamonds, one of your first considerations should be whether the stone is certified. A diamond certificate is an unbiased and complete assessment which declares that the diamond is authentic; not artificial or of lesser quality. A diamond certificate should have the following information: carat weight, colour grade, cut, clarity, measurements, proportion, transparency, polish and symmetry grades, fluorescence, hue and any other characteristics which determine a diamond’s quality. Assurance of the main characteristics: cut, colour, clarity and carat size, as well as purchasing from a trustworthy retailer.
