1. Round Brilliant Cut
The round brilliant cut is the most iconic choice for sustainable jewelry, known for its unmatched sparkle and timeless appeal. This cut is crafted with 57 or 58 precisely angled facets, designed to maximize light reflection and create that signature brilliance. Its perfect symmetry has made it a favorite choice for generations, and it works especially well with lab grown diamonds, where modern cutting techniques help create just the right angles for maximum sparkle.
What Makes Round Brilliants Special
The Round Brilliant's design offers several unique advantages. Its exceptional light performance helps mask slight color variations, making G-H color grades an excellent value choice. While this cut can make inclusions more visible, choosing VS1 clarity or better ensures a visually clean appearance. What truly sets it apart is its superior light performance - no other diamond shape can match its sparkle and rainbow light display, especially under direct lighting. As a practical bonus, its smooth, rounded shape makes it highly resistant to chipping, perfect for daily wear.
When to Choose It:
As the most popular diamond shape worldwide, round brilliant cut diamonds offer maximum sparkle and suit almost any style. Here are their ideal occasions:
- Engagement rings (most popular choice)
- Wedding bands
- 25th wedding anniversary
- Christmas gifts
- Mother's Day
- Professional achievements
- Graduation ceremonies
Round Brilliant: The Timeless Classic (25-70+ years)

2. Princess Cut
The princess cut ranks among the top choices for lab grown diamonds, combining modern geometry with exceptional brilliance. While the most common configuration features 57 facets or 65 facets. As one of the popular fancy shape diamonds, the princess cut is appreciated for its sharp angles and contemporary appeal, standing out alongside other unique cuts like the Asscher, pear, and marquise.
What to Know Before Buying a Princess Cut
When shopping for a princess cut lab grown diamond, there are a few key things to keep in mind. Unlike round diamonds, this square shape tends to show more color, so it's best to choose an H color grade or better to get the most sparkle for your money. The good news is that its unique facet pattern does a great job hiding small flaws, though you'll want to look closely at the corners where imperfections can be more visible. One of the best features of princess cut lab grown diamonds is their amazing sparkle - they create beautiful rainbow effects (especially in larger stones) and offer brilliant shine second only to round diamonds.
Just remember that while these stones are stunning, their pointed corners need extra protection. Make sure to choose a setting that guards these delicate areas to keep your diamond safe during daily wear.

Why the Radiant Cut Shines: Key Features

6. Oval Cut
The oval cut is an elegant elongated variation of the round brilliant cut, typically featuring 69 facets. Created as one of the newer innovations in diamond cutting during the 1960s, the cut has had successful adaptation in lab-grown diamonds, featuring exceptional brilliance to maximize the apparent size of a stone.

The faceting pattern creates an extraordinary interplay of light, while the length gives a far greater surface area than that in a round-cut diamond with an identical carat weight.

- Elegant weddings
- 20th wedding anniversary
