What Is a Princess-Cut Diamond?
The princess cut is a square or slightly rectangular diamond with sharp, clean lines and a dazzling facet pattern. Developed in the 1970s, it’s the most popular non-round shape today — especially for modern engagement rings and statement studs.
Thanks to its angular shape and brilliant faceting, princess-cut lab-grown diamonds offer the ideal balance of edge and sparkle — especially when precision-cut through advanced CVD techniques like ours at Firefly.

Why It’s Loved: Modern Sparkle with an Edge
Unlike round cuts, the princess cut directs more of its brilliance through the crown, giving it a crisper, flashier look. It’s loved for its:
- Geometric brilliance – 76 facets engineered for fire
- Modern edge – perfect for contemporary tastes
- Efficient yield – retains more of the rough stone, which aligns beautifully with Firefly’s low-waste values
Best Uses: Where Princess Cuts Shine Bright
Princess-shaped lab diamonds suit both minimal & statement pieces — and they’re surprisingly versatile when set creatively.
Perfect for:
- Engagement rings (solitaires, halos, split-shank)
- Stackable bands
- Geometric stud earrings
- Contemporary pendants
Style Guide: Who It’s Perfect For
Princess-cut diamonds are bold, confident, and fashion-forward — ideal for someone who loves clean lines, contemporary design, and sparkle with structure.
“You value clarity, direction, and a little edge — and your diamond says so.”
