All About Diamonds: Shapes

All About Diamonds: Shapes
Posted: 27th Apr 15
Round
 
The modern round brilliant cut is the most popular shape of diamond, with around 75% of all diamonds sold being round brilliant cuts. The round shape maximises potential sparkle because of the way its facets reflect back the light. Stunning in any setting, the round brilliant cut is timeless and versatile!
 
 
 
 
 
 
 
 
 
 
Princess
 
Princess cut diamonds have been around since the 1980’s (the modern square cut - square cut diamonds in general have been around for hundreds of years) they are also very popular, like the round brilliant cut, in engagement rings. Their shape is very versatile and so can work in a number of styles of rings. If you like a classic look with a contemporary edge, princess cuts are striking and unique.
 
 
 
 
 
 
 
 
 
 
Oval
 
An oval cut is a modified round brilliant cut - it has the same brilliance and fire but it is elongated. Because of this, the oval cut has the advantage of appearing to have a greater size than that of a round brilliant cut diamond. 
 
 
Marquise
 
Marquise cuts are a rugby shaped, also like an oval cut in the same way it holds similar properties of brilliance and fire to a round brilliant cut and giving the illusion of a greater size. Marquise diamonds have one of the largest surface areas of any diamond shape, so they are a good choice when trying to maximise perceived size. 
 
 
 
 
 
 
 
 
 
 
Pear
 
A pear cut is a combination of the round brilliant and marquise cut, with one tapered point. For an ideal pear cut, the diamond should have excellent or very good symmetry.
 
 
 
 
 
 
 
 
 
 
 
 
Cushion
 
A cushion cut is a square shape with the corners rounded off, much like a pillow, hence the name! It is a very classic cut which has been around for almost 200 years. Recent refinements in its cut have showed a surge in popularity today.
 
 
 
 
 
 
 
 
 
 
 
Emerald
 
An emerald cut has step cuts, rather than lots of little facets like a round brilliant cut. Instead of lots of intense sparkle, emerald cuts instead offer a hall-of-mirrors effect. They were very popular in the early decades of the 20th century in the Art Deco period. They are a popular choice today with fashions leaning toward this era, and for those who prefer the subtle, understated look. 
Inclusions and colour are easier to be seen in an emerald cut as there isn’t all the reflection and sparkle going on like in non-step cut stones to distract. This meaning, emerald cuts tend to be more on the expensive size because the colour and clarity should be above average.
 
 
 
 
 
 
 
 
 
 
 
Asscher 
 
The asscher cut was first produced in 1902 by the Asscher brothers of Holland. It is similar to the emerald cut but is square shaped. It also has larger step-facets, a higher crown and smaller table. This combination often produces a bit more sparkle than an emerald cut which is very subtle.
 
 
Radiant
 
A radiant cut is four sided with no corners like an emerald cut, but has a brilliant cut facet pattern (like the round modern brilliant cut and princess cut) creating a bright and lively look. The radiant cut is a good compromise between a cushion and a princess cut.
 
 
 
 
 
 
 
 
 
 
 
Heart
 
The heart shape is another modified round brilliant cut. Set in a ring, pendant or earrings, the heart shape is a unique shape and an unmistakable symbol of love! The cut looks and works best at around 0.50 carats of larger so you can see the shape properly, especially if claw set.
