Frequently Asked Questions
Why does a 3 carat marquise cut look especially large on the hand? +
The marquise cut has an elongated outline that maximises face-up length. At 3 carats, this
creates exceptional finger coverage and a slimming effect, making the diamond appear larger
than many other shapes of the same weight.
How noticeable is the bow-tie effect in a 3 carat marquise cut? +
Bow-tie can appear in marquise cuts, but at 3 carats it should be subtle when proportions and
facet alignment are correct. Proper cutting reduces shadowing and maintains even light return
across the centre.
Do the pointed tips of a 3 carat marquise cut need special protection? +
Yes. Marquise cuts have pointed ends that should be protected with V-prongs or a bezel-style
design. With secure settings, a 3 carat marquise is suitable for confident, long-term wear.
What color and clarity are recommended for a 3 carat marquise cut lab grown diamond? +
Elongated shapes can show color toward the tips and inclusions along the centre. Many buyers
prefer D–F or D–G color with VVS–VS clarity to maintain a bright, eye-clean look at 3 carats.
How does Variation select 3 carat marquise cut lab grown diamonds? +
At Variation, 3 carat marquise cut Lab Grown diamonds are selected based on verified IGI or GIA
certification, balanced length-to-width ratios, reduced bow-tie appearance, and secure tip
symmetry to ensure strong visual performance.
