Choose a Diamond Shape that will make the ring sparkle

The first step for choosing an engagement ring is choosing the shape of the diamond. It may be that your loved one has an idea of what they want already – they could have had their heart set on a round-brilliant cut, or fancy something a little more unique with an emerald cut - but if you’re sure and need some advice, read through our guide on the different type of diamond cuts for full details.A breakdown of the various types of diamond cuts are included below:

Also known as a round-brilliant cut, this is a cone shaped diamond which is one of the most popular choices for engagement rings. With 58 facets, it maximises light reflection and sparkle – and is known for being the ultimate symbol of love.


Boasting sparkle through its square-shape design, the princess cut allows for an iconic style for the wearer. As another popular choice among ring buyers, the pointed corners of this stone creates a bold statement, and maximises sparkle.


An emerald cut stone provides a higher clarity diamond, with step-cut rectangular facets arranged in a parallel setting. This type of cut is finished off with smooth corners, and is perfect for offering a vintage timeless look.


Featuring a coned based and curved edges, the oval diamond cut catches the light and sparkles exceptionally. Designed in the 1960s, you can expect a timeless ring with the connotations of love and romance entwined in the sparkles of the diamond.


Another popular choice among engagement ring buyers, the pear cut diamond is teardrop shaped, and was designed with new techniques in diamond shaping had been introduced – dating back to the 1400s. This type of cut can be worn pointed towards or away from the wearer.


An elongated shape with pointed ends, the marquise cut is distinctive and original – providing a unique shape for a striking engagement ring. Originally styled on a woman’s smile, it’s designed with sharp ends to complement the wearer’s hands.


Shaped as the name describes, the heart cut stone is the ultimate symbol of romance. The cut of the heart diamond is complex, meaning that it is rarer than others – and is thought to symbolise eternal romance. This cut is perfect for those who love a bit of sparkle, due to its multiple facets.


An alternative cut to the round cut or princess cut, the cushion cut diamond boasts exuberant sparkle and light reflection. Popular among celebrities over recent years, you can select between a more square or rectangular shape to sit on a precious metal band.


The asscher cut is an octagonal diamond with a square shape, designed with layered facets featuring a high crown and deep pavilion. Gaining popularity back in the early 2000s after a small change to the cut technique, this is a great choice for a unique ring.


Oozing sparkle and brilliance, combining both a square and rectangular shape, the radiant cut diamond is designed with 70 facets. This provides a stunning multi-stone ring style – as it was the first square cut diamond with a brilliant cut facet pattern.
