Why Choose Princess Lab Grown Diamond Rings
The princess cut is the second most popular diamond shape after the round brilliant — and it is the clear favorite for anyone drawn to clean geometry and modern design. Its square silhouette and sharp, uncut corners give it an architectural quality that round and oval shapes cannot replicate.
What makes the princess cut truly special is its faceting. The chevron-shaped facet pattern produces a unique sparkle that blends traditional brilliance with distinctive cross-shaped light patterns. The result is a diamond that looks sharp, contemporary, and undeniably striking.
Lab grown diamonds make the princess cut even more compelling. Because lab grown stones cost 40–60% less than mined diamonds, you can afford a larger princess cut or a higher quality grade — maximizing the visual impact that this shape is designed to deliver.
Benefits of Princess Lab Grown Diamond Rings
The princess shape paired with a lab grown diamond brings a powerful set of advantages:
- Modern Aesthetic. The square silhouette and sharp corners give the princess cut a bold, contemporary feel that stands apart from softer, rounded shapes.
- Exceptional Sparkle. The 76-facet chevron pattern produces brilliant fire with geometric light reflections — a sparkle style that is unique to the princess cut.
- Genuine Diamond. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds. They are real diamonds, independently certified and graded on the 4Cs.
- Superior Value per Carat. Princess cuts retain more of the rough diamond during cutting than round brilliants, making them inherently more efficient. Combined with lab grown pricing, the value is outstanding.
- Ethical Origin. No mining, no environmental disruption, no conflict. Every lab grown diamond is created responsibly in a controlled environment.
Lab Grown vs Mined Princess Cut Diamonds
For the princess shape specifically, the lab grown advantage is especially compelling.
Princess cut diamonds are already one of the most value-efficient shapes — they retain approximately 80% of the rough diamond during cutting, compared to around 40% for round brilliants. This natural efficiency, combined with lab grown pricing (40–60% less than mined), means a princess lab grown diamond delivers exceptional size and quality for the budget.
In terms of properties, there is nothing to differentiate. A lab grown princess diamond has the same hardness (10 Mohs), the same refractive index, the same fire and brilliance as a mined one. Independent gemological certification (IGI, GIA) confirms grades are identical across both origins.
If you are weighing different diamond shapes, our round lab grown diamond rings offer the most traditional alternative. For gemstone options with even greater affordability, our loose moissanite stones are also worth exploring.
Popular Ring Settings for Princess Diamonds
Solitaire
A single princess diamond on a clean band lets the square shape and geometric sparkle take full center stage. The solitaire is the most popular princess cut setting — minimal, confident, and endlessly classic.
Halo
A frame of smaller diamonds surrounds the princess center stone, softening the angular shape slightly while adding significant visual size and sparkle. Our halo settings are designed to complement the princess cut's geometry with precision and balance.
Channel Set
Smaller princess or round diamonds set into channels along the band create a seamless, modern look. The channel setting's clean lines mirror the geometry of the princess center stone, creating a cohesive, architectural design.
Cathedral
Cathedral settings feature arches of metal that rise from the band to cradle the diamond, adding height and structural elegance. This setting showcases the princess cut beautifully from the side while keeping the stone secure.
How to Choose the Perfect Princess Lab Grown Diamond Ring
The princess cut has unique characteristics that are worth understanding before you decide:
- Symmetry. A well-cut princess diamond should be perfectly square or near-square, with even faceting across all four quadrants. Look for a length-to-width ratio between 1.00 and 1.05 for a true square shape.
- Cut Quality. Princess cuts do not have a standardized "excellent" cut grade like round brilliants. Evaluate light performance, symmetry, and polish carefully. Grown Leo curates princess diamonds for balanced brilliance and clean light distribution.
- Color Grade. The princess cut can show color in its corners. We recommend D-G for the cleanest appearance, especially in white gold or platinum settings.
- Clarity Grade. VS1-VS2 is the ideal balance of quality and value. Inclusions at this grade are invisible to the naked eye.
- Corner Protection. The sharp corners of a princess cut are its most vulnerable points. Choose a setting with V-prongs or corner prongs that protect these areas from chipping.

Care and Maintenance Tips
Princess cut diamonds are the hardest material on earth but their sharp corners require a little awareness:
- Protect the Corners. The four sharp points of a princess cut are the most susceptible to chipping from hard impacts. Avoid wearing your ring during activities involving heavy force or contact with hard surfaces.
- Clean Regularly. Soak in warm water with mild dish soap for 15–20 minutes. Gently brush around the diamond and beneath the setting with a soft-bristled brush. Rinse and dry with a lint-free cloth.
- Check Corner Prongs. The prongs protecting the corners bear the most stress. Have them inspected at least once a year to ensure they remain secure and intact.
- Avoid Oils and Lotions. Oils from skin and hand products can film the diamond's surface, dulling its sparkle. Clean after exposure.
- Store Separately. Diamonds can scratch other jewelry — and a princess cut's sharp corners can do so more easily than rounded shapes. Keep your ring in its own compartment.
- Wear Confidently. Lab grown diamonds do not degrade, cloud, or lose their sparkle. With proper corner protection, your princess diamond ring will perform beautifully for a lifetime.
