DIAMOND SHAPES

Diamond Shape: From the classic round brilliant and the elegant emerald cut, to the dazzling radiant and flashy trilliant, the shape of the diamond you choose comes down to personal taste.

ROUND BRILLIANT CUT

This is the most popular diamond shape and modern cutting techniques have undergone much research and development to ensure maximum fire and brilliance are captured. It suits almost every hand, and is beautiful in a classic solitaire setting, or accompanied by accent stones. Round brilliant diamonds are often set in a row of three, representing yesterday, today and tomorrow. The standard round brilliant consists of 57 facets; 1 table, 8 bezel facets, 8 star facets 16 upper-girdle facets on the crown; 8 pavilion facets, 16 lower girdle facets; and usually a culet on the pavilion.

PEAR CUT DIAMOND

The pear cut diamond combines the round brilliant diamond with the marquise to create a graceful, teardrop shape that has an elongating effect on the hand. Pear cut diamonds are also very popular when set as a pendant, or as elegant drop earrings. When choosing a pear cut diamond, the shoulders should have a gently but distinctly rounded arch and a length-to-width ratio of 1 to 1.50:1.75

OVAL CUT

Becoming increasingly popular is the oval cut diamond, due to its flattering shape and sparkle matched only by the round brilliant diamond. When choosing an oval cut diamond, check for even shoulders with a gentle slope and a length to with ratio of 1 to 1.30-1.65.

MARQUISE CUT

The Marquise cut diamond creates immediate impact with it’s dramatic shape and sparkling facets. Legend says that the original diamond was commissioned by King Louis XV of France, who wanted the shape to reflect the smile of his mistress The Marquise Madame de Pompadour. Like the woman who inspired it, the woman who wears a marquise diamond is a woman of style! When choosing  a marquise cut diamond, be aware of uneven “wings” or undefined points. Typical length-to-width ratio: 1 to 1.75-2.25.

EMERALD CUT

Taking its name from the traditional shape of the emerald gemstone, the emerald cut is classy, chic and simple.  Belonging to the “step cut” family of diamonds, the shape is most often rectangular, but can also be cut as a “square emerald”. Step cut diamonds are typical of the Art Deco design period and often make an appearance in vintage and estate jewellery. The emerald cut diamond has rows or steps of elongated facets on the crown and pavilion, parallel to the girdle, and with corner facets. The number of rows of elongated facets may vary, although the usual number is three on the crown and three on the pavilion. When choosing an emerald cut diamond, look for stones that are too narrow or missing corners. The beveled corners protect the stone and make it easier to set. Also be aware that inclusions and colour are more apparent with this style, so choose a diamond of higher clarity and colour. Typical length-to-width ratio: 1 to 1.40-1.70.

PRINCESS CUT

Second only to the round brilliant diamond in popularity is the square-shaped princess cut diamond. Originally patented as the Quadrillion diamond, this versatile shape can stand alone as a solitaire, or make a real statement with shoulder accents or a diamond-set band.   When choosing a princess cut diamond, be on the lookout for girdles which are extremely thin and can be prone to chipping.

RADIANT CUT

Combining the elegance of an emerald cut with the sparkle and lustre of a brilliant cut, the radiant cut diamond is a relatively new shape, developed in 1977 by Henry Grossbard of The Radiant Cut Diamond Company. A radiant cut diamond is for a woman who wants to make a statement. The personality of this diamond and its wearer is definitely extroverted! When choosing a radiant cut diamond, look for a length to width ratio of 1.3-1.5:1.

HEART CUT

Romantic and whimsical, the heart cut diamond is essentially an upside-down pear cut diamond, with a cleft at the apex. Heart cut diamonds are extremely popular as gifts for Valentines Day and anniversaries, as well as becoming increasingly popular as a solitaire engagement ring. When choosing a heart cut diamond, look for uneven or flat “wings” or too shallow cleft. Typical length-to-width ratio: 1 to 0.90-1.15.

TRILLION (TRILLIANT, TRIELLE) CUT

Traditionally used as shoulder diamonds to complement a centre stone, the trilliant cut diamond has come into its own and while still rarely seen, this is the shape for a woman who wants something a little different. While the exact design takes into account the preferences of the master cutter, shapes can vary from a traditional triangle with pointed ends, to a more rounded shape with softer edges. When choosing a trilliant cut diamond, look for a ypical length-to-width ratio: 1 to 0.90-1.10.

ASSCHER CUT

Another member of the step cut diamond family, the Asscher was developed in 1902 and is closely associated with the Art Deco design period. Often mistaken for a square emerald cut diamond, the sleek and stylish Asscher requires a four-pronged setting. It is a square step cut with cropped corners and an almost octagonal outline which enhances the stone’s brilliance. Looking into a well-cut Asscher should be like staring into a never ending flight of glittering stairs. When choosing an Asscher cut diamond, we recommend stones of higher clarity and colour, as inclusions are more apparent with this style.

CUSHION CUT

Women who like antique styles will love the cushion cut diamond. Harking back to the early 19th century, the cushion cut diamond is a square-shaped stone with soft, rounded corners and large sparkling facets. Vintage lovers will recognise this as an “old mine cut”, and it is the forerunner to the modern brilliant cut. Stunning as a solitaire or complemented with accent stones, this modern take on a classic is definitely one for lovers of style.
