Frequently Asked Questions
What makes marquise cut lab grown diamonds unique? +
Marquise cut diamonds have an elongated, boat-shaped silhouette with pointed ends,
creating a dramatic, vintage-inspired look. They offer excellent finger coverage and
a striking presence that stands out from more common shapes.
Do marquise cut diamonds look larger than other shapes of the same carat weight? +
Yes. Because of their long outline and shallow spread, marquise diamonds often appear
larger and longer on the finger compared to round or princess diamonds of the same
carat weight, giving a bold, eye-catching look.
What is the bow-tie effect in marquise cut diamonds? +
The bow-tie effect is a dark shadow that can appear across the center of some marquise
diamonds. In well-cut stones, this effect is subtle and balanced by overall brilliance.
Good proportions and symmetry help minimise any distracting dark areas.
What is the best length-to-width ratio for marquise cut lab grown diamonds? +
Most people prefer length-to-width ratios between 1.80 and 2.10. Lower ratios
look slightly wider and softer, while higher ratios appear more slender and elongated.
The ideal ratio depends on your style and finger shape.
Are the pointed ends of marquise diamonds prone to chipping? +
The tips are the most delicate parts of a marquise diamond. A secure setting with protective
V-prongs or a bezel around each point helps prevent chipping and makes the diamond suitable
for everyday wear.
Do marquise cut diamonds show color or inclusions more than other shapes? +
Marquise diamonds have a large open surface, so color and inclusions can be more noticeable,
especially near the tips. Many buyers prefer D–H color and VVS–VS clarity for a
clean, bright look, taking advantage of lab grown value.
Which settings look best with marquise cut lab grown diamonds? +
Marquise diamonds look stunning in solitaire, halo, east-west, vintage-inspired, and
3-stone settings. They can be set vertically for a classic look or horizontally for a
modern, statement style.
How should a marquise diamond be positioned on the finger? +
Traditionally, marquise diamonds are worn with the points aligned along the finger,
which visually elongates the hand. However, east-west settings (across the finger) are
also popular for a contemporary look.
Are marquise cut lab grown diamonds certified by IGI or GIA? +
Yes. Marquise cut lab grown diamonds can be certified by IGI, GIA, and other reputable
gemological laboratories, with full grading reports covering the 4Cs and growth method.
Do marquise cut lab grown diamonds come in different sizes and carat weights? +
Yes. Marquise diamonds are available from under 0.50 ct to 10+ ct, offering everything
from delicate, minimal designs to bold statement rings, pendants, and earrings.
