Collection: Round Cut Lab Grown Diamond Rings

The round brilliant cut is the most popular diamond shape because its 57 or 58 facets are mathematically engineered to maximize light reflection, offering unmatched fire and brilliance. Choosing a lab-grown round diamond gives you the exact same optical, physical, and chemical properties as a mined diamond, but allows you to save 40% to 70% of the cost meaning you can afford a significantly larger carat weight or higher clarity within your budget.

Yes, lab-grown round diamonds are 100% real diamonds. Organizations like the GIA (Gemological Institute of America) and IGI (International Gemological Institute) certify them using the exact same grading standards as mined diamonds (the 4Cs: Cut, Color, Clarity, and Carat). They are made of pure carbon crystal structure and will pass any traditional diamond tester.

Because round diamonds are perfectly symmetrical, they offer excellent face-up size appearance compared to deeper alternative cuts.

1 Carat: Approximately 6.5mm diameter

1.3 to 1.5 Carat: Approximately 7.0mm to 7.3mm diameter

2 Carat: Approximately 8.1mm to 8.2mm diameter

3 Carat: Approximately 9.3mm to 9.4mm diameter

For a round brilliant cut, the Cut grade is the most critical factor of the 4Cs. You should strictly look for an Ideal (IGI) or Excellent (GIA) cut grade. Because round diamonds are designed to maximize sparkle, a poor cut will leak light out of the sides, making the stone look dull or smaller than its actual weight.

No. Because lab-grown diamonds are pure carbon crystals, they are permanently stable. They will never fade, change color, become cloudy, or lose their brilliance over time. Any apparent dullness over years of wearing is simply surface dirt, lotion, or oil buildup, which can be easily cleaned at home with warm water, mild dish soap, and a soft toothbrush.

The perfect symmetry of a round diamond makes it incredibly versatile, but three classic settings tend to perform best:

• Classic Solitaire (4 or 6-Prong): Minimizes metal interference to let the maximum amount of light enter and exit the diamond from all angles.
• Halo Setting: Surrounds the center stone with smaller diamonds, making the center round stone look up to half a carat larger.
• Four-Prong vs Six-Prong: A 4-prong setting highlights more of the diamond's surface area, while a 6-prong setting offers maximum security and emphasizes the diamond's round shape.

Round brilliant cuts are exceptionally good at hiding minor inclusions and masking color due to their intense sparkle. To get the best value for your budget, look for these "sweet spots":

• Color: G to I color grades. These stones look completely colorless to the naked eye when set in white gold or platinum, but cost less than D-F color grades.
• Clarity: VS1 or VS2 clarity grades. These are "eye-clean," meaning you cannot see any internal flaws without a jeweler's magnifying loupe.

Like all luxury items, technology-driven goods, and even mined diamonds, jewelry generally sees a drop in value on the secondary market. However, because you buy lab diamonds without the massive retail markup associated with mined diamonds, you save thousands of dollars upfront. You keep your hard-earned money in your bank account from day one rather than worrying about future resale margins.

Yes. Every lab-grown diamond used in our collection is sustainably grown using advanced technology that eliminates the heavy environmental and social costs associated with traditional earth mining. Our round cut diamonds are individually inspected, tracked, and accompanied by authentic gemological lab certifications ensuring strict origin transparency.
