The shape of a diamond is a customer’s first priority when selecting a diamond for an engagement ring, wedding band or piece of jewelry, whether that is a pendant, bracelet or a pair of earrings. From the classic round shape to fancy shapes like princess or heart, decide the perfect shape for you.

Selecting The Perfect Diamond Shape

An important attribute of a diamond, the shape, which refers to the diamond’s physical form, is usually the first aspect a couple or individual considers when selecting a diamond for their engagement ring or wedding band. It could be dependent on personal taste, for an occasion like your wedding, engagement or as an anniversary gift, or what is trending in the world of diamonds. It could also be related to quality and value. All diamond shapes are unique to each other, with distinct characteristics which determine the quality for each shape. Each shape highlights the 4Cs of a diamond – cut, color, clarity and carat – in varying forms as well. And due to this, each diamond shape offers different forms of beauty, style and brilliance.

Diamond Shape vs Diamond Cut

The term “diamond shape” is often confused with the “cut” of a diamond – one of the four Cs of a diamond. Each shape may be cut to different specifications, which impacts the overall beauty of the stone. However, the type of cut, or quality of it, is determined by different grades, which may or may not be dependent on the shape itself. The “cut” of a diamond describes how well the diamond has been polished, and that determines the way light is reflected throughout the stone’s facet arrangement. It also determines light refraction, sparkle and scintillation.

Uniglo Diamonds suggests to select a diamond with a cut grade of Very Good and above (Very Good, Excellent) to get maximum beauty and value for money. The diamond shape’s length-width ratio is also of importance. A greater length to width ratio implies that the diamond will be longer and skinny, while a lower ratio means the diamond is more circular/square in appearance.

Diamond Shapes – The Popular & The Classic   

Round diamonds are the most popular and classic shape, however, many customers are equally attracted to the unique look of “non-round” or “fancy shaped” diamonds. These diamond shapes include: heart, princess, emerald, cushion, asscher, radiant, oval, pear or marquise. Some diamond shapes cause the facets on the pavilion, or underside, to meet at a point, resulting in maximum light return. Other diamond shapes highlight the clarity of the diamond by the way they are cut, and feature parallel facets on the pavilion, resulting in a subtle shimmer while heightening clarity. Every shape has a story of its own, and a beauty unlike any other, just like every woman has her own unique style and personal taste.
