Question 1

How much does a marquise engagement ring cost?

Accepted Answer

A marquise engagement ring costs the setting plus the diamond. The setting depends on the style and metal — platinum costs more than 14K gold — and the diamond depends mostly on carat weight. A marquise shows more size for its weight than any other cut, so your carat goes further. Prices change daily, so today's live prices are below.

Question 2

How big is a marquise diamond at each carat weight?

Accepted Answer

A marquise is long and narrow with two pointed ends, so it shows more surface from the top than any other cut of the same carat weight — it looks the biggest for its weight and lengthens the finger. A common length-to-width ratio is about 1.85 to 2.1. Compare the millimeters, not just the carats.

Typical sizes of a well-cut marquise diamond (single certified stones at about 1.9 to 2.2 length-to-width, so exact mm vary with the ratio you choose):

1 carat — about 10.3 × 5.3 mm
1.5 carat — about 12.4 × 6.2 mm
2 carat — about 13.7 × 6.3 mm
3 carat — about 15.1 × 7.6 mm
4 carat — about 15.8 × 8.4 mm
5 carat — about 19.4 × 8.6 mm

Question 3

What is a marquise cut diamond?

Accepted Answer

A marquise is a long, narrow diamond with two pointed ends and a brilliant facet pattern — sometimes called a boat or eye shape. It was cut to order for a French king in the 1700s, which is where its regal name comes from. It sparkles like a round but reads much longer on the hand.

Question 4

What is the bow-tie in a marquise diamond?

Accepted Answer

The bow-tie is a dark, bow-shaped shadow across the middle of a marquise (or oval or pear) that isn't cut well. Every marquise has a slight one, but a good cut keeps it faint. Choose an eye-clean, well-cut stone and watch the 360° video to check the bow-tie before you buy.

Question 5

Which setting styles suit a marquise diamond?

Accepted Answer

You can set a marquise in almost any style, and the key is protecting its two pointed ends. The most popular are a solitaire with V-prongs on the points, a halo, a three stone, and an east-west setting that lays the marquise sideways. Each setting in the grid above guards the points.

Question 6

Which metals can I choose for a marquise engagement ring?

Accepted Answer

Every marquise setting comes in platinum or in 14K or 18K gold, in yellow, white or rose. Yellow and rose gold look warm, so a diamond with a faint tint looks natural in them, and you can choose a lower color grade. White gold and platinum look bright and cool. Platinum costs more than gold.

Question 7

What wedding band goes with a marquise engagement ring?

Accepted Answer

A marquise has a point at each end, so a straight band can leave a gap or sit against a tip. A curved, contoured or notched band nests around the point and sits flush — the cleanest match. A plain straight band still works with a simple solitaire marquise.
