Lab Diamond Round Cut Engagement Rings

Round Engagement Ring Styles

A solitaire ring showcases this shape in its purest form, letting the cut speak for itself. This timeless style remains the most requested design for good reason. For those seeking additional presence, shoulder set pieces add complementary stones along the band. Three stone arrangements offer symbolic meaning alongside visual impact. Whatever your preference, the round shape adapts beautifully to any setting.

About the Brilliant Cut

Developed in the early 20th century, this shape was engineered for maximum light performance. The 57 facet pattern is mathematically optimised to return the most light to the eye, creating exceptional fire. This makes it the benchmark against which all other cuts are measured. The symmetrical form also hides inclusions well, meaning you can often choose a slightly lower clarity grade without any visible difference. The brilliant diamond remains the most requested for proposals worldwide.

Colour and Clarity

This shape's exceptional light return can make hue more noticeable than in other cuts. For white metals like platinum, we recommend G grade or above for the best visual result. In yellow or rose gold, you can often go slightly lower as the warm metal tone masks any faint tint. When it comes to clarity, VS2 or SI1 grades typically appear eye clean, allowing you to prioritise carat size within your budget.

Ethical Options

Our pieces offer the same optical and physical properties as mined stones. Each is created in controlled conditions and comes with independent certification. This allows you to select a larger carat size or higher quality grade within the same budget. For couples who value ethics alongside beauty, this represents a meaningful choice without compromise on sparkle or durability.

FAQs

Are round shapes more expensive?
Yes, this shape typically costs 20-30% more than fancy shapes of the same carat weight. This is because more rough material is lost during cutting to achieve the precise 57 facet pattern that maximises sparkle.

What does a round engagement ring mean?

The round shape symbolises eternity with no beginning or end. It's the classic, timeless choice that has remained popular for over a century. Choosing this style signals appreciation for tradition and enduring elegance.

Is round or oval more flattering?

Ovals can elongate shorter fingers while rounds suit most hand shapes universally. The round offers more sparkle due to its optimised facet pattern, while ovals appear larger for the same carat weight.
