DIAMOND SHAPE GUIDE
Marquise Cut Diamonds in Melbourne
Compare marquise cut diamonds by ratio, bow-tie effect, face-up spread, point alignment and setting protection with GemTrove guidance.
What is a marquise cut diamond?
A marquise cut diamond is an elongated fancy-shaped diamond with two pointed ends and curved sides. It is known for elegance, length and strong visual presence.
Navette outline
The long pointed shape creates a distinctive vintage-to-modern diamond silhouette.
Finger lengthening
The shape can make the finger appear longer and often looks large from the top.
Visual review
Check bow tie, symmetry, point alignment, spread and real-life appearance.
Point protection
Both pointed ends should be protected by V-prongs, claws or suitable bezel-style design.
Best marquise cut diamond length-to-width ratio
The best ratio depends on preferred style. Many customers prefer a balanced marquise around 1.75 to 2.15, while shorter stones look fuller and longer stones appear more slender.
| Ratio | Visual appearance | Best suited for |
|---|---|---|
| 1.60 to 1.74 | Shorter, fuller marquise | Softer and wider-looking designs. |
| 1.75 to 2.15 | Classic balanced marquise | Solitaire, halo, vintage-inspired and three-stone rings. |
| 2.16 to 2.30 | Longer and more slender | Elegant designs with strong finger coverage. |
| Above 2.30 | Very elongated marquise | Specialty designs needing careful bow-tie and point review. |
Bow-tie effect and face-up spread
A bow-tie effect is a darker area across the centre of elongated fancy-shaped diamonds. A slight bow tie can be normal, but a strong dark bow tie can reduce beauty. Marquise diamonds are also known for strong face-up spread, but spread should be balanced with brightness and symmetry.
Bow-tie check
Use video, 360 imaging, proportion review, ASET or Ideal-Scope where available.
Millimetres matter
Compare length and width, not only carat weight.
Brightness
Review even light across the centre and tips.
Depth and table
A very shallow or deep marquise can affect sparkle and apparent size.
Marquise diamond setting styles
Marquise cut diamonds are striking in classic and modern ring designs. They can be set north-south, east-west, in a halo, or as part of a three-stone design.
Solitaire
Highlights the long navette outline with protected pointed ends.
Halo or vintage-inspired
Adds presence and suits the historic character of the shape.
East-west
Creates a modern horizontal look.
Three-stone
Pairs well with rounds, pears, tapered baguettes or smaller side stones.
Natural vs lab-grown marquise cut diamonds
Marquise cut diamonds are available in both natural and lab-grown options. The right choice depends on budget, origin preference, size goals and long-term expectations.
| Option | Best for | What to check |
|---|---|---|
| Natural marquise | Clients valuing geological origin and traditional rarity | Bow tie, tip condition, outline, spread, colour, clarity and certificate. |
| Lab-grown marquise | Clients wanting a larger look or higher specification within budget | Growth disclosure, report details, visual performance and value expectations. |
| Side-by-side comparison | Clients comparing size, shape and price | Real viewing helps because similar reports can look different. |
Frequently Asked Questions
What is the best length-to-width ratio for a marquise cut diamond?
Many customers prefer a marquise diamond ratio between 1.75 and 2.15 because it gives a balanced elongated shape.
Do marquise cut diamonds have bow tie?
Yes, marquise cut diamonds can show bow-tie effect. A mild bow tie may be normal, but a strong dark bow tie can reduce beauty.
Do marquise diamonds look bigger than round diamonds?
Marquise diamonds often appear larger from the top because their long shape gives strong face-up spread. Measurements and visual performance should still be checked.
Which setting is best for a marquise diamond?
Marquise diamonds suit solitaire, halo, vintage-inspired, east-west and three-stone designs. V-prongs or protective settings at both pointed ends are strongly recommended.
Are marquise cut diamonds durable for everyday wear?
Yes, when set properly. The two pointed tips are the main areas to protect, so the setting should be well made and checked regularly.
Should I choose a natural or lab-grown marquise cut diamond?
Natural marquise diamonds are often chosen for traditional rarity and geological origin. Lab-grown marquise diamonds can offer a larger look or higher specification within budget.
Does a GIA or IGI certificate show bow tie in a marquise diamond?
No. A certificate records grading details and measurements but does not clearly show bow-tie strength, outline, brightness or tip quality.
Can GemTrove custom make a marquise diamond engagement ring?
Yes. GemTrove can create custom marquise diamond engagement rings using CAD design, natural or lab-grown diamonds, coloured gemstones and different metal options.
Why do pointed ends need protection?
The tips are the most delicate areas of a marquise diamond and should be protected with suitable claws, V-prongs or bezel-style settings.
What should I inspect before buying a marquise diamond?
Inspect ratio, bow tie, point alignment, face-up spread, colour, clarity, inclusions near the tips and setting suitability.
