Princess Cut Lab Diamonds: Complete Guide, Prices & Engagement Rings
Princess-cut diamonds are square brilliant-cut stones with pointed corners, combining modern geometric appeal and brilliant sparkle.
The princess diamond captures light in flashes of fire and brilliance, like a modern crown of geometry and sparkle. This relatively recent innovation transforms the traditional square shape into a brilliant showcase of light performance, making it the second most popular diamond shape after round brilliants.
Unlike older square cuts that prioritised elegance over sparkle, the princess lab diamond delivers both contemporary appeal and maximum light performance - the perfect balance for today's discerning buyers seeking modern sophistication.
What Makes Princess Cut Diamonds So Popular?
The princess cut emerged in the 1980s as diamond cutters sought to create a square shape that could rival the brilliance of round diamonds. This innovative cutting style features a square face-up appearance with pointed corners and brilliant-style faceting that maximises light return.
Quick Take: Princess Cut Essentials
- Shape: Square brilliant cut with pointed corners
- Brilliance: Exceptional light performance, second only to round cuts
- Value Advantage: 20-30% less expensive than comparable round diamonds
- Modern Appeal: Contemporary geometric design perfect for today's styles
- Collection Size: 2,410 Princess cut lab diamonds available at Juvetti
What sets princess diamonds apart from other square cuts is their unique faceting structure. While emerald cuts use step-cut faceting, princess cuts employ brilliant-cut faceting with multiple triangular and kite-shaped facets radiating from the centre. This creates intense fire and scintillation approaching the light performance of round lab diamonds.
Laboratory-grown princess diamonds benefit significantly from controlled cultivation processes. The precise crystal structure required for optimal Princess cut performance can be more consistently achieved in laboratory environments, resulting in superior light performance and fewer structural weaknesses.

How Do Princess Cut Diamonds Compare to Round Diamonds?
Understanding how princess diamonds compare to round brilliants helps buyers make informed decisions based on style preferences, budget considerations, and practical factors.
Direct Performance Comparison
| Factor | Princess Cut | Round Brilliant | Winner |
|---|---|---|---|
| Brilliance | Excellent light performance | Maximum brilliance standard | Round (slight edge) |
| Fire & Colour Play | High fire, dramatic flashes | Consistent scintillation | Princess (more dramatic) |
| Price Value | 20–30% less per carat | Premium pricing | Princess (better value) |
| Modern Appeal | Contemporary geometric look | Classic timeless appeal | Personal preference |
| Durability | Requires corner protection | No vulnerable points | Round (more durable) |
Are Princess-Cut Diamonds Cheaper Than Round?
Choose Princess if you want: Modern geometric style, better value per carat, dramatic fire and colour play, distinctive appearance that stands apart from traditional choices.
Choose Round if you prefer: Maximum brilliance, classic timeless appeal, ultimate durability, widest setting selection, proven value retention.
The practical differences become apparent in daily wear and long-term value. Round diamonds' lack of pointed corners makes them more suitable for active lifestyles, whilst princess cuts require protective settings but offer distinctive modern aesthetics at superior value points.
For size considerations, 1-carat lab diamonds in a princess cut often appear larger than round equivalents due to their square face-up dimensions.
Why Choose Princess Cut for Your Engagement Ring?
Princess cut engagement rings represent contemporary romance perfectly, combining the symbolism of traditional proposals with modern aesthetic sensibilities that appeal to today's couples.
Why Princess Cuts Excel in Engagement Rings
Contemporary appeal resonates strongly with couples seeking alternatives to traditional round solitaires. The clean geometric lines complement modern lifestyles whilst delivering exceptional sparkle that rivals any diamond shape.
Superior value proposition allows couples to invest in larger stones or higher quality grades within the same budget. The 20-30% cost advantage over round diamonds provides genuine financial benefits without compromising beauty.
Distinctive appearance ensures your engagement ring stands apart from traditional choices whilst maintaining broad appeal. Princess cuts offer uniqueness without being trendy or limiting future style flexibility.
Popular Princess Cut Engagement Ring Styles
Solitaire settings showcase princess diamonds beautifully, with the geometric precision creating a striking contrast against simple band designs. Four-prong settings positioned at corners protect whilst maintaining maximum sparkle.
Halo designs work exceptionally well with princess cuts, where surrounding diamonds can echo the square shape or create interesting contrasts. Square halos emphasise geometric precision, whilst round halos soften angular appearances.
Three-stone settings featuring princess cuts create stunning symmetry, particularly when centre and side stones share the same shape. This creates cohesive geometric patterns that appeal to contemporary design sensibilities.
Vintage-inspired settings can successfully incorporate princess cuts when designs acknowledge the cut's modern nature. Art Deco-influenced mountings work particularly well, as their geometric patterns complement the Princess cut precision.

What's the Best Setting to Protect Princess Cut Diamonds?
Princess-cut diamonds require specific setting considerations to protect their pointed corners whilst showcasing their geometric beauty. Understanding these requirements ensures both stunning appearance and long-term durability.
Essential Corner Protection Methods
V-prong settings offer superior corner protection by wrapping metal around each point. This style provides excellent security whilst maintaining the princess cut's distinctive square appearance - the ideal balance of protection and beauty.
Corner-positioned four-prong settings work well when prongs are placed at corners rather than sides. This placement protects vulnerable points whilst minimising metal coverage, maintaining maximum light entry and sparkle.
Bezel settings provide maximum protection by surrounding the entire diamond perimeter with metal. Modern bezel designs can enhance rather than hide geometric appeal, creating sleek contemporary appearances perfect for active lifestyles.
Setting Styles That Enhance Princess Cuts
Channel settings suit princess cuts beautifully in wedding bands and eternity rings. The continuous line of square diamonds creates striking geometric patterns that emphasise the cut's modern appeal.
Tension settings create dramatic contemporary appeal by holding princess diamonds through metal tension alone. These ultra-modern mountings require expert craftsmanship but create stunning visual impact.
East-west settings offer unique alternatives by mounting princess diamonds horizontally. This orientation creates completely different aesthetics whilst making fingers appear longer and more elegant.

Quality Assessment: The 4Cs for Princess Diamonds
Evaluating Princess cut quality requires understanding how traditional grading criteria apply specifically to this modern cut, plus additional factors unique to square brilliant diamonds.
Cut Quality: Foundation of Princess Diamond Beauty
Unlike round brilliants, princess cuts don't have standardised cut grades from major institutes. Understanding key proportions becomes essential for optimal selection.
Length-to-width ratio determines visual appeal. Most buyers prefer ratios between 1.00 and 1.05 for a perfectly square appearance. Ratios up to 1.10 still appear attractively square, whilst higher ratios begin looking rectangular.
Table percentage typically ranges from 65-75% for optimal light performance. Crown angles between 10-15 degrees paired with pavilion depths of 65-75% usually produce excellent brilliance.
Best Clarity for Princess Cut Engagement Rings
Inclusion hiding allows excellent value in princess cuts. The brilliant faceting pattern effectively masks most inclusions, making SI1 and SI2 clarity grades often appear eye-clean. For exceptional clarity, consider VVS1 lab diamonds for investment-grade quality.
SI1 clarity represents the sweet spot for most Princess cut engagement rings, offering eye-clean appearance at excellent value. The brilliant faceting disguises minor inclusions that would be visible in step cuts.
VS2-VS1 grades provide additional peace of mind for larger stones (1.5+ carats) where clarity becomes more critical. These grades ensure complete eye-clean appearance under all lighting conditions.
VVS1-VVS2 grades suit perfectionist buyers or investment pieces where ultimate clarity matters more than budget considerations. These premium grades showcase the princess cut's brilliance without any clarity distractions.
Colour and Clarity Strategy
Colour masking represents one of the princess cuts' significant advantages. The brilliant faceting helps hide colour tinting, making G-I colour grades appear whiter than equivalent grades in step cuts.
For absolute colourlessness, D colour lab diamonds in Princess cut create stunning combinations of geometric precision and pure white light.

How Are Princess Cut Lab Diamonds Made to Perfection?
The creation of exceptional Princess cut lab diamonds requires precise control over both diamond cultivation and cutting processes. Laboratory growth provides significant advantages for achieving optimal quality.
Laboratory Cultivation Benefits
Crystal structure optimisation becomes crucial for princess cuts, which require specific crystal orientations for maximum light performance. Laboratory cultivation allows precise control over development, ensuring optimal rough material.
Chemical Vapour Deposition (CVD) excels at producing large, clear crystals ideal for princess cuts. The layer-by-layer growth creates a uniform structure without natural formation irregularities.
High-Pressure High-Temperature (HPHT) methods produce princess-quality crystals with excellent clarity and minimal strain patterns. Controlled environments eliminate variables that create inclusions in natural diamonds.
How Should You Style Princess Cut Diamonds?
Princess diamonds adapt beautifully across style preferences, from ultra-modern minimalism to classic elegance with contemporary touches.
Modern Contemporary Styling
Geometric harmony represents princess cuts' greatest strength in contemporary design. Clean lines and precise angles complement modern architecture, minimalist aesthetics, and current fashion perfectly.
Metal choices significantly impact appearance. White gold and platinum emphasise modern precision, yellow gold adds warmth that softens angles, whilst rose gold creates romantic contemporary appeal popular among younger buyers.
Stackable designs work beautifully with princess cuts, where multiple bands create striking geometric patterns. The uniform shape allows perfect alignment in stacked arrangements.
Coordinated Jewellery Collections
Complete sets featuring princess cuts create cohesive contemporary looks. Consider matching pieces across our collections of necklaces, earrings, and bracelets for geometric elegance.
Mixed shape combinations allow princess cuts to complement other shapes in sophisticated designs. The geometric precision creates interesting contrasts when combined with oval cut lab diamonds or round brilliants.

Care and Investment Protection
Princess-cut diamonds require specific care to maintain beauty and protect pointed corners. Understanding proper maintenance ensures lasting value.
Daily Care Essentials
Gentle handling protects corners from impact damage. While diamond hardness prevents scratching, corner stress concentration makes careful handling important for durability.
Regular cleaning maintains optimal light performance. Princess cuts' multiple facets accumulate oils that diminish sparkle. Weekly cleaning with mild soap restores maximum brilliance.
Setting inspection becomes particularly important. Corner protection elements should be checked regularly to ensure continued security.
