NEED TO KNOW: DIAMOND SHAPE

When starting your search for an engagement ring, choosing the shape of the central diamond is a great place to start. Round brilliant diamonds represent a high proportion the engagement rings purchased from us; this is down to the abundance of fire, life and brilliance, they simply are the most sparkly. That said, our advise is to go with your instinct and if your girlfriend has been strongly suggesting she likes a pear shape, take the hint!!

Diamonds fall into two categories, brilliant cuts which are those cut to optimise light return throughout the stone, and Step cuts which are designed to showcase the clarity of the diamond. Examples of brilliant cut diamond shapes are: round, cushion, princess & pear, whilst emerald and asscher are examples of step cut diamonds. It is important to remember that diamond shape is not the same as diamond cut.

Diamond-Shapes-Overview

 

Where as brilliant cut diamonds showcase luminosity, Step cuts, on the other hand, are designed to showcase the clarity of the stone. Here, elongated parallel facets make up the pavilion section. The diamond still sparkles beautifully, but there is an emphasis on the purity and elegance of the stone. Step cuts include emerald and asscher shapes.



Remember that shape is not the same as cut – when we talk about cut specifically, we are referring to the individual arrangement of light-reflecting facets in a single stone and the way that this has been engineered. Three emerald-cut diamonds may have varying cuts of varying quality, and the better the cut, the higher the reflection of light, and the more fire and brilliance your diamond will have. Cut is one of the Four Cs (also including colour, clarity and carat), and is also a very important consideration when choosing a diamond.

While some shapes are more popular than others, and some provide better value for money, the most important thing is to choose a diamond that suits your bride-to-be. Think about her own personal style, and how that can be reflected in a precious gem. Gentle, fiery, quirky, bold or romantic – there is a diamond shape out there for everyone.

ROUND DIAMONDS

Round-cut diamonds are overwhelmingly the most popular of all shapes. Around 90 per cent of all diamonds cut in this way, and close to 75 per cent of diamond engagement rings are set with round brilliants. First developed around a century ago, time has allowed for careful developments that have continually increased the ways in which round cuts optimise a diamond’s natural dazzling radiance.

PRINCESS CUT DIAMONDS

Taking the second spot is the princess cut. These diamonds are brilliant cut, like their round counterparts, but are instead crafted into an elegant square shape. Sleek and modern, they are also beautifully versatile, sitting well in many different settings and rings.

CUSHION CUT DIAMONDS

Similar to a princess- or square-cut diamond, the cushion cut features rounded edges, creating a gentler, pillow-like shape (hence the name). This classic cut used to be called the ‘old mine cut’, and it has actually been around for a whole century more than the round cut. It was the most popular cut for a long time, and is still sought after today for a range of settings.

EMERALD DIAMONDS

This shape was originally developed for, unsurprisingly, emeralds. However, it is a strikingly elegant cut for a diamond, too. Reduced depth and a wide table demonstrate crystal clarity and dramatic steps show off colour and mirror-like shine.

ASSCHER CUT DIAMONDS

Unique and eye-catching, this shape complements both contemporary solitaire settings and attractive vintage-style designs. First developed around the turn of the eighteenth century by Joseph Asscher, it is a step-cut square with cropped corners that provides more scintillating brilliance than an emerald cut. This is due to a smaller table, high crown and larger steps.

RADIANT CUT DIAMONDS

If you love the shape of an emerald cut, but miss the glittering vitality of a round brilliant, a radiant-cut diamond provides both. It is essentially a rectangular cut, which has been cut using the facet pattern applied to round brilliants and princess cuts. With greater carat weight included in the depth of the stone, it creates a sensational diamond that is full of fire.

OVAL DIAMONDS

Chic and feminine, oval-cut diamonds are similarly designed to round brilliants, and are equally impressive in their sparkle. This symmetrical shape looks great in lots of different settings, and can even make what might be a relatively small diamond appear larger.

PEAR DIAMONDS

As the name might suggest, pear-shaped diamonds are just that – rounded on one side like a round brilliant, with a gently tapered point on the other much like a marquise. The pear-cut diamond’s characteristic teardrop design requires a well-proportioned and symmetrical diamond, but when cut well, they are intensely radiant and gracefully flattering on the hand.

MARQUISE DIAMONDS

Tapered to a point on either end, the marquise cut is brave and bold. Its distinctive shape is enhanced by a large surface area, which means that it stands out even when the actual size of the diamond is reduced.

HEART SHAPED DIAMONDS

Pretty and romantic, heart-shaped cuts are popular for diamond engagement rings as they symbolise what a proposal is all about – love. Their balanced faceted sections will sparkle in any setting, but traditional Claddagh compositions often feature this particular cut.
