Engagement Rings FAQ

What makes a round brilliant cut diamond engagement ring unique?

The round brilliant diamond is a diamond cut that’s been developed over many decades of trial and error, making it unique in the dedication that has gone into ensuring the perfect angles to achieve the maximum brightness in a diamond. The modern brilliant cut diamond with 57 facets (58 with a culet) that we know today came to fruition in 1919, with changes taking place as technology continued to develop in the first half of the 1900s. A round brilliant cut diamond is a testament to the time and expertise that goes into designing a diamond with the perfect amount of sparkle- no other cut can compete.

Does a round brilliant diamond look bigger than other shaped diamonds of the same carat?

The depth of a round brilliant cut diamond really denotes whether it has a large ‘spread’ (i.e., its perceived size for its carat weight when viewed from the top). A shallower diamond may have a bigger spread, but light return may be poor, as the angles might not be correct to bounce light back to the eye. The same goes for a deep stone, although it will have a smaller spread than a perfectly cut stone of the same carat weight. Round brilliant cut diamonds will look bigger for their size when compared to princess and emerald cuts, but smaller against elongated shapes such as marquise or pear diamond cuts.

How do I choose the right carat size for a round brilliant cut engagement ring?

There’s no right or wrong when picking a carat size for a round brilliant cut diamond ring. It really comes down to what size stone you like on your finger, what design you’d like to go for, and how much you wish to spend. The best way to work out your preferred size is to book an appointment to see us in person – we have a range of stones ready to select from.

How to maximise the sparkle of a round brilliant cut engagement ring?

Light is the key component in any diamond’s sparkle. Maximising the amount of light entering the stone is the key to ensuring the diamond displays the best brilliance. An open setting, such as a 6 or 4 claw solitaire with a cathedral style band, is one of the most popular and aesthetically pleasing ways to make sure there’s light coming into the diamond from all angles.

Are round brilliant diamonds more expensive than other cuts?

Diamond cut prices generally vary depending on how much of the diamond crystal is wasted during the cutting process. A princess cut diamond is normally priced lower than a round brilliant cut diamond, as there’s very little diamond lost, and the crystal structure is an octagon, so it has a square cross-section. A round brilliant cut diamond does have more wastage as you’re cutting a circle from an octahedral profile, but not as much wastage as other cuts, such as a pear or a marquise, so it tends to sit in the middle of the range for pricing, although demand can also make prices rise.

Should I choose a cushion or a round cut diamond for my engagement ring?

A round brilliant cut diamond is a classic, symmetrical shape that produces the maximum brilliance from the stone and suits both modern and traditional designs. Cushion cut diamonds are a more traditional cut, more suited to vintage and antique styles, although they still look fantastic in modern solitaire settings. They’re normally not as symmetrical as a round brilliant cut diamond, and tend to be rectangular, if only slightly. They do still have a fantastic sparkle. Your choice of ring style will denote whether a round brilliant cut diamond or a cushion cut diamond will look best.

How can I pair a custom round brilliant diamond engagement ring with a wedding band?

The design of your engagement ring will denote the best style for your wedding ring. It’s important to ensure your engagement ring setting is sitting off the band if you wish to fit a straight wedding band flush against your ring in future. Some clients opt to have their engagement ring setting right on the finger so it’s less likely to get caught, and a fitted wedding ring can be designed to flow around the contours of the engagement ring. The key is to have your wedding ring design complement your engagement ring, not compete with it.

What metal types pair best with a round brilliant diamond?

Round brilliant cut diamonds look great in all precious metal types. It’s important to choose a colour that you love, but also one that complements the diamond’s colour. You may wish to put a more yellow diamond (lower colour grade) into a yellow gold setting, as it will help disguise the colour. Likewise, you may wish to set a higher colour grade diamond in a white metal to enhance the stone further, as the yellow gold reflecting through it may give it a yellow tinge. Coloured diamonds are normally paired with a metal colour that will make the colour appear more saturated; a yellow diamond in bright 18ct yellow gold, or a pink diamond in rose gold.

Are all round diamonds round brilliant diamonds?

A round brilliant cut diamond is a round diamond with a brilliant faceting pattern. Other round diamonds have a different number of facets or overall profile, which affects the light return, size and colour of the diamond. A good example is a round rose-cut diamond. They’re a beautiful round shape, but only have facets on the top of the stone with a flat bottom. This means that it is easier to see directly through the stone as light passes through the stone differently. Round rose-cut diamonds suit vintage designs with closed backs, but wouldn’t suit an open solitaire setting like a round brilliant cut would.

What is the best colour rating to choose for a round brilliant cut diamond?

The colour of a round brilliant cut diamond is often rated using the GIA colour scale, which ranges from D (colourless) to Z. Most diamonds seen in engagement rings range from D to J, with J stones having a more yellow or brown tinge. Metal colour, your preferences, and your budget will come into play when selecting a diamond colour. Anything G and above generally appears colourless to the eye.

What is the best cut rating to choose for a round brilliant cut diamond?

Round brilliant cut diamonds are the cut that GIA and other diamond grading laboratories base their grading systems on. A perfectly cut round brilliant cut diamond would achieve an ‘ideal’ rating. This means that the cut symmetry, polish and cut proportions are all excellent. This is the best option to pick for optimum light return, but diamonds with a combination of excellent and very good ratings can still be beautiful stones. It’s always important to consider other characteristics for your custom round round brilliant cut engagement ring, such as colour, fluorescence and inclusions. Our expert sales team can guide you through this process with ease. [blog post link? What are the 4cs of diamonds?]
