1 carat princess cut diamonds

1 Carat Princess Cut Diamonds: Natural Square Brilliants

For a four sided stone with real sparkle, the 1 carat princess cut diamond is the usual pick, and it often costs less per carat than a round with the same grades. It is a square brilliant with sharp corners, so the one thing to get right beyond color and clarity is a setting that guards those corners.

Why a 1 carat princess cut diamond costs less than a round

Rounds are the most expensive common shape per carat, and princess cuts often come in below them at the same weight and grades. That makes the princess one of the simpler ways to get a one carat stone with strong color and clarity for less. You give up the round's soft outline and a little of its brilliance, and in return you get a crisp, modern square that still flashes like a brilliant.

The carat mark still matters. A stone a few points under one carat costs noticeably less and looks the same once set, so widen your search slightly below the round number if the report figure is not important to you.

Guarding four corners

Its four points are the most exposed part of the stone, so they need V prongs or a bezel. Four V prongs, one capping each corner, are the classic hold and show nearly all of the diamond. A bezel wraps the whole outline in metal and is the most protective setting of all, a good fit for active hands, though it returns slightly less light; bezel ring settings show the look.

Avoid ordinary rounded prongs placed along the sides, which leave those tips bare. A low head with snug corner prongs is also less likely to catch on fabric or take a direct knock, so check the profile view before you choose. A sturdy 1 carat princess cut diamond ring is all about how those four points are covered.

Clarity and color in a square brilliant

This shape hides inclusions well because it is a brilliant, so VS2 and many SI1 stones are clean to the eye. The exception is the corners: an inclusion near one is both easier to spot and a weak point, so favor stones with clean corners.

G or H suits white gold and platinum, which show warmth; yellow and rose gold hide a warmer stone, so an I or J can look white there. Fancy shapes carry no single GIA cut grade, so judge each stone on video, looking for even brightness right out to the corners and a crisp outline with equal sides. If two candidates look alike, choose the one whose corners come to clean, unchipped points in the video.

Natural princess or lab grown?

Choose natural for rarity and lasting value. A mined princess usually comes with a GIA report and keeps much more of its value on resale. Choose lab grown for budget: the same material and look cost far less, though resale is low. Compare 1 carat princess lab grown diamonds with the stones here, or see finished pieces among princess natural diamond engagement rings.

Whichever you choose, Rare Carat sells direct and is the merchant of record on every order, so you deal with one company from checkout to delivery.

FAQs

Is a princess cut more durable than a round?

No. Both are diamond, 10 on the Mohs scale, but this cut has four pointed corners that can chip if they take a hard knock, while the round outline has no points at all. With V prongs or a bezel covering those corners, a princess cut engagement ring is perfectly practical for everyday wear.
