Marquise Lab Diamonds Guide by London's Top Jeweller
What Is a Marquise Lab Diamond?
A marquise lab diamond showcases the distinctive boat-shaped silhouette that has captivated jewellery enthusiasts for centuries, combining vintage glamour with contemporary ethical sourcing. This elegant cut features pointed ends and gracefully curved sides, creating an elongated shape that appears larger than round diamonds of equivalent carat weight whilst offering exceptional finger-flattering properties.
The marquise cut's unique geometry maximises surface area, making it an intelligent choice for buyers seeking visual impact alongside value. Originally commissioned by King Louis XV of France for his mistress, the Marquise de Pompadour, this cut embodies aristocratic elegance and sophisticated taste that transcends fleeting fashion trends.
Laboratory-grown marquise diamonds at Juvetti maintain identical chemical composition, optical properties, and physical characteristics to natural stones, created through sustainable cultivation processes that eliminate environmental damage. Our comprehensive collection of 4,569 marquise lab diamonds demonstrates the remarkable variety available within this distinguished cut, offering exceptional quality across diverse price points.
The elongating effect of marquise diamonds creates an illusion of longer, more slender fingers, making this cut particularly flattering for those seeking elegant proportions. This practical benefit, combined with the cut's inherent sophistication, explains why marquise diamonds continue attracting discerning buyers who appreciate both beauty and functionality.
How Much Is a Lab Grown Marquise Diamond?
Marquise lab diamond pricing reflects exceptional value compared to natural alternatives, with laboratory cultivation providing cost savings of 60-80% whilst maintaining identical quality characteristics. At Juvetti, our marquise lab diamonds start from remarkably accessible price points, making luxury accessible without compromising ethical standards or visual impact.
How Much Does a 1 Carat Marquise Diamond Cost?
One carat marquise lab diamonds at Juvetti begin at £360, representing extraordinary value for premium quality stones that deliver maximum visual impact. This pricing makes marquise cuts incredibly attractive compared to 1 carat lab diamonds in round cuts, which typically command higher prices due to universal popularity and cutting waste.
The cost advantage of laboratory-grown stones becomes particularly evident in larger carat weights, where natural marquise diamonds command premium pricing due to rarity. Our sustainable cultivation process eliminates mining-related costs whilst ensuring consistent quality across our entire collection.
Factors Affecting Marquise Lab Diamond Prices
Quality grades significantly influence marquise lab diamond pricing, with colour, clarity, and cut quality creating price variations within each carat weight category. For those seeking premium colour grades, F colour lab diamonds provide excellent value whilst ensuring beautiful appearance across the entire stone.
Certification levels from recognised institutions add value and provide buyer confidence, with certified stones commanding appropriate premiums that reflect their verified quality. All Juvetti marquise lab diamonds include proper certification, ensuring transparency and supporting long-term value retention.
Are Marquise Diamonds More Expensive?
Marquise diamonds typically cost less than round diamonds of equivalent quality due to superior rough diamond utilisation during cutting. The elongated shape allows cutters to preserve more of the original crystal, reducing waste and creating cost efficiencies that benefit buyers seeking maximum value compared to premium round brilliant cuts.
The cutting complexity of marquise diamonds requires skilled craftsmanship to achieve proper proportions and minimise bow-tie effects, but this specialisation doesn't significantly impact pricing compared to complex fancy shapes or the universally popular round brilliant cut.
Market demand influences marquise diamond pricing, with these distinctive stones appealing to buyers seeking unique alternatives to traditional round cuts. This targeted appeal often results in excellent value propositions for buyers who appreciate the marquise cut's sophisticated aesthetic.
Marquise vs Popular Diamond Cuts Cost Comparison
Round diamonds typically command premium pricing due to universal popularity and cutting complexity, making marquise cuts attractive alternatives for budget-conscious buyers seeking elegant sophistication without the round cut premium.
Princess cut diamonds offer similar value propositions to marquise stones, though the princess cut's geometric appeal differs significantly from marquise elegance. Both cuts provide excellent alternatives to round diamonds for buyers seeking distinctive character.
Are Marquise Diamonds Out of Fashion?
Absolutely not - marquise diamonds continue experiencing renewed appreciation among buyers seeking distinctive alternatives to conventional round cuts. The current jewellery landscape celebrates vintage-inspired designs and unique personal expression, positioning marquise cuts perfectly within contemporary fashion trends alongside other elegant alternatives like oval cut diamonds.
Celebrity endorsements and high-profile engagements featuring marquise diamonds demonstrate their enduring appeal and sophisticated positioning within luxury markets. These public displays reinforce marquise diamonds' status as elegant choices for discerning buyers who appreciate timeless beauty.
The cyclical nature of fashion trends suggests that marquise diamonds' current resurgence reflects broader appreciation for vintage glamour and distinctive personal style. Rather than following fleeting trends, marquise buyers choose enduring elegance that transcends temporary fashion movements.
Modern Marquise Diamond Appeal
Contemporary settings showcase marquise diamonds beautifully, with modern designers creating innovative mounting styles that highlight the cut's elegant proportions. From minimalist solitaires to elaborate halo designs, marquise diamonds adapt beautifully to current aesthetic preferences.
Social media influence increasingly features marquise diamonds as distinctive choices for buyers seeking Instagram-worthy pieces that stand apart from conventional selections. This digital exposure introduces new generations to marquise beauty and sophisticated appeal.
Why Not Buy a Marquise Diamond?
Potential considerations for marquise diamond purchases include their pointed ends, which require protective settings to prevent chipping, and the bow-tie effect that appears in some stones. However, these characteristics are easily managed through proper selection and setting choices, making them minor considerations rather than significant deterrents.
The pointed tips of marquise diamonds need careful protection through appropriate setting styles such as V-prongs or bezel mounting that secure vulnerable areas. Professional jewellers understand these requirements and can recommend optimal setting approaches for long-term durability.
Bow-tie effects appear as dark areas across the centre of some marquise diamonds, but skilled selection and proper cutting minimise this phenomenon. Quality marquise diamonds from reputable sources like Juvetti undergo careful evaluation to ensure minimal bow-tie presence and optimal light performance.
Addressing Common Marquise Concerns
Setting requirements for marquise diamonds involve protecting pointed ends whilst showcasing the stone's elegant proportions. Modern setting techniques provide excellent security without compromising visual appeal, making marquise diamonds practical choices for regular wear.
Maintenance considerations for marquise diamonds mirror those of other cuts, requiring regular cleaning and professional inspection to maintain optimal appearance. The pointed ends need occasional attention, but proper care ensures decades of beautiful wear.
How to Tell If a Marquise Diamond Is Real?
Professional certification provides the most reliable method for verifying marquise diamond authenticity, with recognised institutions like GIA offering comprehensive grading reports that confirm natural or laboratory origin alongside quality characteristics.
Visual inspection techniques include examining the stone's brilliance, checking for sharp facet edges, and observing light reflection patterns that distinguish real diamonds from simulants. However, these methods require expertise and proper equipment for accurate assessment.
Laboratory Testing for Diamond Authentication
Gemological instruments provide definitive identification of diamond authenticity, measuring thermal conductivity, electrical properties, and optical characteristics that distinguish diamonds from simulants like cubic zirconia or moissanite.
Certification verification through grading institute databases confirms report authenticity and provides detailed quality information that supports informed purchasing decisions. This verification process ensures buyer confidence and investment protection.
What Is a Good Depth for a Marquise Diamond?
Optimal depth percentages for marquise diamonds typically range from 58% to 62%, providing the ideal balance between brilliance and visual appeal. These proportions ensure proper light return whilst maintaining the elegant silhouette that defines marquise beauty.
Depth calculations involve measuring the distance from table to culet as a percentage of the stone's width, with proper proportions creating optimal optical performance. Marquise diamonds outside ideal depth ranges may exhibit reduced brilliance or compromised visual appeal.
Ideal Marquise Diamond Proportions
Length-to-width ratios significantly impact marquise diamonds' appearance, with ratios between 1.75:1 and 2.25:1 creating pleasing proportions that showcase the cut's elegant characteristics. Personal preference influences ideal ratio selection within this range.
Table percentages for quality marquise diamonds typically range from 53% to 63%, balancing fire and brilliance whilst maintaining proper proportions. These measurements work in conjunction with depth percentages to create optimal visual performance.
Marquise Lab Diamond Quality Considerations
Minimising Bow-Tie Effects
Bow-tie phenomena appear as dark shadows across marquise diamonds' centres, varying in intensity based on cutting quality and proportions. Superior cutting techniques and careful stone selection minimise these effects, ensuring optimal light performance and visual appeal.
Expert evaluation during selection identifies stones with minimal bow-tie presence, providing buyers with confidence in their choice. Juvetti's rigorous quality standards ensure that our marquise collection features stones with excellent light performance and minimal optical irregularities.
Colour Considerations for Marquise Cuts
Colour selection becomes particularly important in marquise diamonds, as the elongated shape can concentrate colour at the pointed ends. Premium grades like D colour diamonds provide absolute colourlessness, whilst F colour alternatives offer excellent value whilst ensuring beautiful appearance across the entire stone.
Setting metal choice influences colour perception in marquise diamonds, with white metals enhancing colourless appearance whilst yellow or rose gold can complement slightly warmer stones beautifully.
Clarity Priorities for Marquise Diamonds
Clarity considerations become crucial in marquise diamonds due to their large table facets and elongated shape that can make inclusions more visible. VVS1 clarity grades provide exceptional purity for those seeking investment-grade stones with flawless appearance.
Best Settings for Marquise Lab Diamonds
Protective Setting Options
V-prong settings provide optimal protection for marquise diamonds' pointed ends whilst maintaining elegant appearance and maximum light entry. These specialised prongs secure vulnerable areas without compromising the stone's distinctive silhouette.
Bezel settings offer maximum protection through complete metal encirclement, creating sleek, modern appearances that suit contemporary design preferences whilst ensuring long-term durability for active lifestyles.
Engagement Ring Settings
Solitaire mountings showcase marquise diamonds' inherent elegance without competing elements, creating timeless pieces that emphasise the stone's distinctive beauty. These classic settings suit diverse style preferences whilst providing practical durability.
Halo designs enhance marquise diamonds' apparent size and brilliance through surrounding accent stones, creating dramatic impact whilst maintaining the cut's sophisticated proportions. These settings particularly suit buyers seeking maximum visual impact within their budget.
Marquise Diamonds in Different Jewellery Types
Marquise Diamond Engagement Rings
Engagement ring applications showcase marquise diamonds' romantic heritage and flattering proportions beautifully. The elongating effect creates elegant finger proportions whilst the distinctive shape symbolises unique love and sophisticated taste.

Caring for Marquise Lab Diamonds
Daily Wear Considerations

Regular cleaning maintains optimal brilliance and fire, with simple home cleaning methods involving mild soap solution and soft brushing adequate for routine maintenance between professional services.
Professional Maintenance
Periodic inspection by qualified jewellers ensures setting security and identifies potential issues before they become problems. The pointed ends of marquise diamonds particularly benefit from regular professional attention to maintain optimal protection.
Investment Value of Marquise Lab Diamonds
Market Appreciation Potential
Marquise lab diamonds offer excellent investment characteristics through their combination of distinctive appeal, superior value pricing, and growing market acceptance of laboratory-grown stones. The unique aesthetic ensures continued desirability among sophisticated buyers seeking alternatives to mainstream round brilliant cuts.
Rarity factors within laboratory-grown diamonds favour well-cut marquise stones, as the technical complexity of achieving optimal proportions whilst minimising bow-tie effects requires considerable expertise and careful stone selection.
