The pieces of jewellery found throughout our collections and those designed on individual request have contributed to a reputation here at the boutique for stunning, luxury pieces that are as unique as the individuals who wear them. A fundamental aspect of finding your dream diamond engagement or wedding ring is deciding on your desired diamond shape. Listed below are some of the shapes available and their defining characteristics.




Many of our customers select a round diamond because it offers the most flexibility in the balancing of the four C’s – cut, colour, clarity and carat – without compromising the diamonds’ brilliance and shine. Apart from their superior light-reflecting properties, round diamonds are part of the brilliant-cut group of diamonds, meaning they have 58 facets. Round diamonds tend to be more sought after with 75 – 80% of diamonds sold being round in shape. This in turn makes them more valuable as they are in high demand. In addition, on a per carat basis round, brilliant cut diamonds are more valuable than fancy shape diamonds due to the technique used to cut the shape being the most technically difficult. A greater amount of rough diamond is required to create its final shape and it displays the most brilliance of all the shapes when cut perfectly.

In the boutique we currently have a range of rings featuring round diamonds such as our Round Brilliant Cut Diamond Halo Engagement Ring showcased to the right. If you’d like to know more about this particular piece or round diamonds and our range of options please contact us at the boutique and we’ll be happy to assist.


Cushion cut diamonds are square or rectangular in shape with soft, rounded corners andImage_DiamondSelection_Shape_product_02cusion remain highly valued for their warm glow and vintage elegance. As one of the oldest types of fancy cut diamonds, with the design dating over 300 years, cushion cut diamonds are admired for their ability to capture and reflect a kaleidoscope of colours. They were one of the most popular styles of cuts from the early 1800s to the early 1900s and since the revival of classic art deco styles, they have once again become a favourite for couples looking for a more antique style in their wedding or engagement rings. Cushion cut diamonds tend to possess great levels of fire (the showing of spectral colours) and are adored for their ability to disperse light. They are also the preferred shape for fancy coloured diamonds as they can naturally enhance the intensity of the stone.


The pear shape diamond is a soft-sided fancy shape that combines the marquise and oval cutImage_DiamondSelection_Shape_product_03pear shapes. Resembling a teardrop, pear cut diamonds contain 58 facets and just like a round brilliant diamond, they are renowned for their brilliance and timeless sophistication. This shape of diamond is traditionally always worn with the narrow-end facing towards the fingertip. Similar to oval cut diamonds, pear shaped diamonds should always be perfectly symmetrical where the point aligns with the centre of the rounded end. The classic length to width ratio of this cut is 1.40 – 1.70, which can be altered depending on personal preference. In contrast to a round diamond, more care should be taken with pear shaped diamonds, as the points can be fragile if not supported well by the jeweller or not cut well in the first place. As with all diamonds they should be well cared for to ensure they remain in good condition.


Emerald cut diamonds account for only 3% of diamonds in the world, making them amongst the most unique available. Emerald cut diamonds are generally rectangular and as the name suggests, the shape was originally developed as a guide to cut emeralds of the gemstone variety. Emerald cut diamonds have a very distinct, vintage look that remains extremely popular today, particularly in recent years with the returning popularity of vintage styles. Unlike brilliant cut diamonds, emerald cuts have fewer facets resulting in less ‘sparkle’ and a more subtle, icy brilliance as the cut produces a hall-of-mirrors type of effect with reflections of light and dark planes. As a result of the elongated shape to the cut of the diamond, the emerald cut can help to elongate the finger they sit on, in doing so helping to make the finger appear longer and more slender.


Princess cut diamonds are a favourite for engagement rings, such as our Twin Halo Princess Cut Diamond Engagement RingImage_DiamondSelection_Shape_product_05Princess shown to the right. A princess cut diamond has four pointed corners and the diamond is square or rectangular in shape. One of the main reasons for the popularity of princess cut diamonds is that they have the flexibility to be incorporated into most designs. Another selling point is that princess cut diamonds are often available at more accessible prices than round cut diamonds of comparable sizes due to a lower level of wastage when cutting the rough diamond.



The marquise diamond, as seen in our Marquise Chocolate Diamond Ring to the right, is an adapted form of a brilliant-cut diamond, similar in shape to an oval diamond with pointed ends. The marquise cut creates a long and narrow shape as well as a large crown surface helping give the impression of a larger diamond. This makes it an ideal choice for those after great value. Another advantage of marquise shaped diamonds is that, similar to oval shaped diamonds, their elongated shape (when vertical) can make fingers appear longer and more slender. The dramatically pointed ends of this cut are beautiful, however the points can sometimes be a little more temperamental then other points as they finish with such fine depth. Marquise shape diamonds will all have a bowtie effect through the centre of the stone, a region of the diamond that can appear slightly darker through the width of the stone and loosely resembles the shape of a bowtie. This cannot be avoided and is seen throughout all marquise cut diamonds however the effect can be minimised by selecting a diamond that is bright all the way through. Avoiding a bowtie that is overly dark and unpleasant will make a better choice now and in years to come.


The modern asscher cut diamond shares similarities with a square emerald cut diamond, but often possesses more brilliance as a result of its higher crown and larger step facets. Like the square emerald shape, asscher cut diamonds also have cropped corners, presenting a somewhat octagonal shape. These wider corners mean that the eight sides of the stone capture light from all angles to produce a pattern of repeated squares distinctive of this unique cut. An asscher cut diamond is a classic and elegant style that also works well when combined with other gemstones. Asscher cuts can demand a more premium price because they require rough diamonds of supreme clarity and colour characteristics to be used, and a talented cutter to master the delicate faceting.


The oval shape diamond is an elegant and sophisticated choice for the modern woman, and yetImage_DiamondSelection_Shape_product_08oval another modified version of the brilliant-cut diamond. The oval shape cut is a fantastic alternative to the round brilliant cut as the two shapes look amazing and reflect light beautifully. While you may see a round and oval diamond of the same carat weight, the more elongated shape of the oval diamond can make it appear larger than a round cut diamond. The cut of an oval shaped diamond results in a beautiful reflection of light with the best properties and appearance to the eye often occurring at a length to width ratio of approximately 1.50. The overall shape of the diamond is important, when looking for an oval cut diamond be sure to check that all four quadrants of the diamond are equal, the culet is central, and the curve is even and smooth.



A radiant cut diamond can make a stunning, classic choice for an engagement ring as their brilliance and vivid fire offer considerable ‘wow’ factor, even in smaller carat weights. This cut results in a square shape with no corners that is cut very deeply and contains an average of 70 facets. Radiant cut diamonds look fabulous in a range of styles due to the versatility of their cut, they are also probably one of the most forgiving shapes, with their high levels of sparkle offering protection against flaws such as the appearance of inclusions, blemishes or colour tints (keeping in mind many of these flaws are very rarely visible to the naked or untrained eye). Radiant cut diamonds often show great value due to the spread of the diamond and you will find a lot of coloured diamonds cut in the radiant style because of their highly reflective nature and ability disperse the colour around the diamond.



As an unmistakable, global symbol for love, the heart shaped diamond can be a popular choice for engagement rings because of its connotations. Heart shaped diamonds have a defined cleft with two lobes sloping down to form a sharp point at the end. Perfect symmetry is the most important characteristic in this cut when evaluating a heart shaped diamond. For this reason the preferred length to width ratio for heart shaped diamonds is 1:1. Most heart shaped diamonds have between 57 and 59 facets depending on the size and shape of the diamond. Smaller facets tend to be favoured as they usually create greater brilliance and fire qualities than what’s seen in larger facet sections. Heart shaped diamonds are unique in that they are incredibly versatile and can look amazing in a number of styles, especially when paired with additional stones such as in our Oval and Heart Diamond ‘Trilogy’ Engagement Ring pictured to the right.
