Princess lab-grown diamonds deliver brilliant-cut fire in a crisp, modern square — often at a lower price per carat than a comparable round.
The princess is the most popular of the square cuts because it delivers the sparkle of a round brilliant in a clean, contemporary square. Its faceting is brilliant-style, so it throws plenty of fire and white light, but the geometric outline reads as modern and architectural rather than traditional. For buyers who love sparkle but want something a little different from the ubiquitous round, the princess hits a sweet spot.
It is also one of the smartest values in fine diamonds. A princess is cut from rough that would largely be lost in shaping a round — in fact two princess stones can come from a single crystal — so it tends to cost less per carat than a round of the same color and clarity. That efficiency, combined with its strong sparkle and clean lines, makes the princess a favorite for solitaires, channel-set bands, and three-stone rings.
Protect those corners. The princess has four sharp ninety-degree corners, and they are the part most likely to chip if left exposed. Always plan a setting with protective V-prongs that cover each corner — this is the standard mounting, and with it a princess wears reliably every day.
Keep it square. For the classic crisp square, look for a length-to-width ratio of about 1.00 to 1.05. At that range the eye reads it as truly square. A slightly higher ratio gives a gently rectangular princess if you prefer, but most buyers want the balanced square.
Use the brilliant faceting to save. Because the princess scatters light and hides small inclusions and faint color, you can often choose G or H color and an eye-clean SI and still get a bright, white-looking stone. Glance at the corners on the video, where color can show a touch more than the center.
Check depth and sparkle on video. Princess cuts can carry weight in their depth, so compare the millimeter measurements to be sure the spread is not hidden below. On video, look for lively, even sparkle across the whole face rather than dull patches.
Plan a V-prong setting that covers all four sharp corners. It is the standard mount and the key to durability.
A length-to-width ratio of 1.00–1.05 reads as a true, crisp square. Go higher only if you want it slightly rectangular.
Brilliant faceting hides color and inclusions, so G–H and SI often look white and clean for less than a round.

Usually, yes. A princess cut is created from rough that would otherwise be largely wasted in cutting a round, so two finished stones can come from a single piece of rough. That efficiency means a princess typically costs less per carat than a round of the same color and clarity, which is a big part of why it has long been a favorite for buyers who want a brilliant, sparkly stone with a modern square outline at a friendlier price.
The four sharp ninety-degree corners are the most vulnerable part of a princess cut and can chip if they are left exposed. The solution is simple: set the stone with protective V-shaped prongs that cover each corner, which is the standard way princess cuts are mounted. With the corners shielded, a princess cut holds up well to everyday wear.
For a true square princess, look for a length-to-width ratio of about 1.00 to 1.05. At that range the stone reads as crisply square to the eye. If you prefer a slightly rectangular princess, you can go a little higher, but most buyers want the classic square, so staying at or below 1.05 keeps the outline looking balanced and intentional.
Reasonably well. The princess is a brilliant cut, so its faceting scatters light and helps mask small inclusions and faint body color better than a step cut like an emerald. You can often choose a near-colorless grade such as G or H and an eye-clean SI clarity and still get a bright, white-looking stone. Corners can show a touch more color than the center, so glance there on the video.
Yes. The princess cut rose to popularity as the leading square brilliant and remains a classic, especially for buyers who want a clean, geometric, modern alternative to the round. It works beautifully in solitaires, channel-set bands, and three-stone rings. Trends shift, but the crisp square outline and strong sparkle of a princess cut keep it a perennial choice.
