A marquise reads longer on the finger than any other shape of the same weight, which is its whole appeal — and the reason its proportions have to be right.
A dark band across the centre of the stone, shaped like a bow-tie, caused by the pavilion angles shading light away from your eye. Almost every marquise shows some. A faint one is normal and disappears as the stone moves; a heavy one stays dark under every light and is the single most common reason a marquise disappoints in person. No grading report scores it, so it has to be judged by eye or on video.
What length-to-width ratio should a marquise have?
Between 1.85 and 2.10 suits most buyers. Below 1.85 the outline starts to look stubby and loses the elegance people choose a marquise for; above 2.10 it looks dramatic but the points become fragile and the bow-tie usually worsens. The ratio is a matter of taste within that band, not a quality grade.
Does a marquise look bigger than a round of the same carat?
Yes, noticeably. A marquise spreads its weight across a long, shallow outline, so it presents more surface to the eye than a round brilliant of identical weight. That is why it is a favoured shape for buyers who want visual size for the budget.
Are the points on a marquise likely to chip?
They are the most vulnerable part of the stone, and they need protecting in the setting. V-prongs that cover both tips are the usual answer. Loose, the points should be examined for existing nicks; set, they should never be left exposed on a ring worn daily.
What clarity works well in a marquise?
A marquise is a brilliant cut, so its faceting hides inclusions better than a step cut does. VS2 and SI1 frequently face up clean. What matters more than the grade is inclusion placement: something under the centre or near a point is far more visible than the same inclusion near the girdle.
Which settings suit a marquise?
Set lengthwise it elongates the finger; set east-west it reads modern and unexpected. Solitaires with V-prongs are the most common choice, and a marquise also works as a side stone flanking a round or oval centre.
