📜 A Brief History of Princess Cut Diamonds
🔹 The Square Revolution
The princess cut is a relatively modern invention, first created in the 1960s as a variation of the “profile cut.” It was perfected in the 1970s by Israeli diamond cutter Betzalel Ambar, who sought to combine the brilliance of a round diamond with the sharp, geometric appeal of a square.
🔹 The Rise of Popularity
By the 1980s and 1990s, princess cuts surged in popularity thanks to their high brilliance, lower price point, and modern style. Jewelers quickly embraced the cut as an alternative to the round brilliant, offering buyers sparkle at a lower cost per carat.
🔹 The Modern Princess Cut
Today, princess cuts are cut with 57–76 facets, depending on the cutter’s style, and they consistently rank as the second-most popular engagement ring diamond shape worldwide.
💡 Real-World Example: Tiffany & Co. introduced their first princess-cut engagement rings in the 1980s — and the style remains a bestseller today.
💡 What Makes Princess Cut Diamonds Unique?
Princess diamonds are distinct for their sharp geometry and brilliant sparkle.
- Shape: Perfectly square or slightly rectangular with sharp, pointed corners.
- Brilliance: Second only to round brilliants in light performance.
- Price Advantage: 20–30% cheaper than rounds because they waste less rough diamond during cutting.
- Modern Appeal: Edgy, bold look compared to the softness of rounds or cushions.
- Face-Up Size: Appear slightly smaller than rounds, but their angular lines create strong finger presence.
📊 Fun Fact: Because princess cuts use up to 80% of the original rough diamond, they are one of the most efficient cuts — meaning better value for buyers.
🔍 The 4Cs of Princess Cut Diamonds
1. ✂️ Cut: Sparkle Meets Symmetry
Princess cuts don’t have a standardized “ideal cut” like rounds, but cut quality is crucial.
- Depth: Ideal between 64–74%.
- Table: Ideal between 67–72%.
- Symmetry: Square princesses (length-to-width ratio of 1.00–1.05) are most desirable.
- Corners: Must be protected by prongs — they are prone to chipping.
💡 Pro Tip: Always prioritize excellent cut, polish, and symmetry grades for maximum brilliance.
2. 🎨 Color: Corners Show More Tint
Princess cuts reveal color slightly more than rounds, especially at the corners.
- For white gold/platinum settings, aim for G–H color or better.
- For yellow/rose gold, I–J can still look bright.
- Fancy color princesses (yellow, pink, champagne) are popular because the square shape enhances saturation.
3. 🔍 Clarity: Corners Are Key
Princess cuts hide inclusions fairly well due to their brilliant faceting, but inclusions in corners can threaten durability.
- Best Value Range: VS2 or SI1 clarity (eye-clean).
- Avoid inclusions near corners, as they weaken the stone structurally.
- Look for centrally placed inclusions, which are less risky.
4. 💎 Carat: Maximizing Size & Value
Princess cuts are excellent value compared to rounds:
- Typically 20–30% less expensive than a round of the same carat weight.
- Appear slightly smaller face-up than rounds (due to deeper cuts), but their sharp edges provide bold coverage.
- A 1.0ct princess measures about 5.5mm across, versus a 6.5mm round.
💡 Example: A buyer choosing a 1.0ct princess over a 0.85ct round saved $2,000 and still got a fiery, brilliant stone.
