Question 1

How much does a princess cut engagement ring cost?

Accepted Answer

A princess cut 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 princess usually costs a little less per carat than a round of the same grade. Prices change daily, so we show today's live prices below.

Why a little less? A square princess is cut from the rough crystal with less waste than a round, so you often get more carat for your money. Color, clarity and cut move the price too. See today's prices: 1 carat princess · 2 carat · princess settings

Question 2

How big is a princess cut diamond at each carat weight?

Accepted Answer

A princess cut is close to square, so it can look a little smaller from the top than a round of the same carat weight — more of its weight sits in the depth. Its width and length are almost equal. Compare the millimeters, not just the carats, when you shop.

Typical face-up sizes of a well-cut princess cut diamond (square, so length ≈ width):

1 carat — about 5.5 × 5.5 mm
1.5 carat — about 6.3 × 6.3 mm
2 carat — about 6.9 × 6.9 mm
3 carat — about 8.0 × 8.0 mm
4 carat — about 8.8 × 8.8 mm
5 carat — about 9.4 × 9.4 mm

Question 3

What is a princess cut diamond?

Accepted Answer

A princess cut is a square (sometimes slightly rectangular) diamond with sharp, pointed corners and brilliant faceting, so it sparkles much like a round. It is the second most popular cut after the round brilliant. The look is modern and clean, and the shape suits almost any setting style.

Question 4

How do I stop a princess cut's corners from chipping?

Accepted Answer

A princess cut's sharp corners are its one weak spot — a hard knock can chip a corner. The fix is the setting: choose one with V-shaped prongs that cup and cover each corner, or a bezel that wraps the whole edge in metal. Every setting in the grid above protects the corners this way.

Question 5

Which setting styles suit a princess cut diamond?

Accepted Answer

You can set a princess cut in almost any style. The most popular are solitaire (often with V-prongs), halo, three stone and channel-set bands. A solitaire shows the clean square outline, a halo circles it with small diamonds to add size, and three stone adds side stones. Each setting in the grid is made for a princess center.

Question 6

Which metals can I choose for a princess cut engagement ring?

Accepted Answer

Every princess 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 warm tint looks natural in them and you can pick a lower color grade. White gold and platinum look bright and cool. Platinum costs more than gold.

14K or 18K? 18K is 75% gold with a richer color. 14K is 58.3% gold, so it is a little harder and resists scratches better. Browse white gold princess settings →

Question 7

What wedding band goes with a princess cut engagement ring?

Accepted Answer

A princess cut has straight, square edges, so a straight wedding band sits flush against it — a clean, natural pair. A channel-set or plain band works well. If your ring has a halo or sits high, a straight band can leave a small gap, so a curved or notched band that hugs the setting fits better.
