Expert Insights from Armans' Jewellers

This guide was written with insights from Arman Arzumanian, Master Jeweller at Armans Fine Jewellery, who has over 25 years of experience crafting bespoke engagement rings in Sydney. 

Why is the round brilliant cut the most popular diamond for engagement rings? 

The round brilliant cut diamond has become the world’s most chosen engagement ring shape because of its unmatched light performance. With 58 facets, it maximises brilliance, fire, and scintillation. At Armans, our jewellers recommend round engagement rings for couples seeking a timeless style that will remain elegant for generations to come.

How do jewellers at Armans Fine Jewellery select the best round brilliant diamonds? 

We hand-select each diamond with a focus on cut quality, as this has the greatest impact on sparkle. At our Sydney boutique, our jewellers only choose stones that achieve excellent grades in symmetry, polish, and light return, ensuring every round diamond engagement ring meets the highest standards.

Which setting best showcases a round engagement ring? 

Round diamonds are incredibly versatile and look stunning in a variety of settings. Solitaire and six-prong designs highlight the stone’s brilliance, while halo settings add extra sparkle. Many clients at Armans choose a diamond band to complement the centre stone with added shimmer.

What size ratios or carat weights do you recommend for round engagement rings? 

Most clients opt for diamonds between 1 –2 carats, though the “ideal” size depends on finger shape, style preference, and budget. During your consultation, our jewellers will guide you through proportion and cut to ensure the diamond looks perfect for your hand.

Do round engagement rings suit every finger shape? 

Yes. The round brilliant cut is universally flattering, which is why it remains such a versatile and popular choice. Whether your fingers are slender or broader, the symmetry of a round diamond offers balance and elegance.

Why choose a round brilliant diamond if you want a timeless design? 

The round brilliant has been the standard of elegance for more than a century. Its enduring appeal, sparkle, and versatility make it the perfect choice for couples wanting a ring that will remain stylish across every generation.

Frequently Asked Questions 

What Does A Round Diamond Symbolise?

A round cut ring is extremely traditional. This classic cut symbolises the fact that this couple is traditional, conservative, endlessly faithful, and very loyal.

Are Round Engagement Rings Popular?

Yes, round brilliant cut diamonds are the most popular choice worldwide. Their exceptional sparkle and classic design ensure they remain the go-to option for couples in Australia and beyond.

What makes a round diamond sparkle more than other shapes?

Round brilliant diamonds are mathematically engineered for light reflection. Their perfect symmetry allows light to enter and refract with maximum brilliance. This precision cut ensures that round diamonds consistently outshine other fancy shapes such as cushion or princess cuts.

How do round diamonds compare to oval or cushion cuts in price and look?

Round diamonds generally carry a price premium due to cutting waste and demand. Oval and cushion cuts may offer a larger spread for the same carat weight, but they cannot match the brilliance of a round. Couples wanting a truly classic, symmetrical look tend to favour round engagement rings.
