Marquise Cut Lab Grown Diamonds – Your Questions Answered
What is a marquise cut lab grown diamond?
+
A marquise cut lab grown diamond is an elongated diamond with pointed ends and a brilliant-cut facet pattern. Its unique boat-shaped silhouette offers strong sparkle, a luxurious vintage feel, and a flattering, finger-lengthening appearance. It is grown using CVD or HPHT technology and has the same composition and brilliance as a mined marquise diamond.
Why are marquise cut lab grown diamonds unique?
+
Marquise cut lab grown diamonds stand out for their dramatic long shape, pointed ends, and eye-catching brilliance. Their elongated design creates exceptional finger coverage and a distinctive vintage-to-modern aesthetic not found in many other diamond shapes.
Do marquise cut lab grown diamonds look bigger than other shapes?
+
Yes. Marquise diamonds often appear larger than many other shapes of the same carat weight due to their long, narrow silhouette and large face-up surface area. This makes them a great choice for maximum visual presence.
What is the best length-to-width ratio for marquise diamonds?
+
The most popular length-to-width ratios for marquise diamonds range from 1.75 to 2.25. Lower ratios look fuller, while higher ratios create a slimmer, more elongated appearance.
Do marquise cut diamonds show a bow-tie effect?
+
Yes, marquise cut diamonds can show a bow-tie effect if the cut is not well balanced. A high-quality marquise diamond will minimise the bow-tie while maintaining strong brilliance across the entire surface.
Which 4Cs matter most for marquise cut lab grown diamonds?
+
For marquise diamonds, cut and colour are important. The elongated shape can reveal colour near the pointed ends, so D–H colour grades are ideal. Brilliant faceting hides inclusions well, so VVS–VS clarity is popular, with well-chosen SI stones also appearing clean.
Are the pointed ends of marquise diamonds fragile?
+
The pointed ends of marquise diamonds require protection, but the right setting solves this. V-shaped prongs or protective claws at both tips will keep the diamond secure and prevent chipping during daily wear.
Which settings look best with marquise cut lab grown diamonds?
+
Marquise diamonds look stunning in solitaire, halo, east-west, vintage-inspired, and three-stone settings. They also pair beautifully with tapered baguettes or pear-shaped side stones for a refined, elegant look.
Are marquise cut lab grown diamonds good for engagement rings?
+
Yes. Marquise cut lab grown diamonds are an excellent choice for engagement rings due to their dramatic shape, large face-up size, and vintage-meets-modern appeal. They offer a unique take on brilliance and elegance.
Are marquise cut lab grown diamonds certified and easy to maintain?
+
Yes. Marquise cut lab grown diamonds can be certified by IGI, GIA, and other global labs. Maintenance is simple: clean with warm water and mild soap, avoid harsh chemicals, and have the prongs and tips checked periodically to ensure secure wear.
