About the Princess Cut Cut

Princess cuts have the second-highest brilliance of any cut, behind rounds. They're square, modern, and efficient — you get maximum carat weight in a geometric footprint. The sharp corners require V-tip prongs to protect them from chipping.

1 Carat — What You're Getting

One carat is the most searched diamond weight globally — it hits a psychological threshold where the stone is unambiguously significant. A 1ct lab-grown at StudsDirect runs $580–$980 depending on shape, cut, and clarity — versus $4,500–$7,000 for an equivalent natural diamond at retail.

A 1ct round brilliant is approximately 6.5mm diameter — clearly present in all settings, photographs beautifully, and reads as the classic engagement ring weight.

Color Guidance for Princess Cuts

Princesses concentrate color at the corners. G color or above for white metal settings. H is acceptable in yellow gold where the warmth blends.

Clarity Guidance for Princess Cuts

VS2 is the standard choice. The brilliant facets mask inclusions well, but avoid SI2 where inclusions fall in the center table.

Setting Recommendations

Four-prong with V-tip corners is non-negotiable for princess cuts — unprotected corners chip on impact. Channel or pavé bands complement the angular aesthetic.

The 1ct size works on all hand sizes. On smaller hands (size 4–5), it reads as a statement piece. On larger hands, it reads as refined.

MT

"Every princess diamond we carry goes through the same QC process I applied when grading for export clients at SEEPZ. The cut grade isn't a box to check — it's the difference between a stone that looks alive and one that sits flat. For the 1 Carat princess, I look specifically at the table percentage and crown angle. We don't carry stones that don't meet that standard."
