Diamonds have captivated humanity for centuries, with their brilliance, fire, and timeless appeal. Among the many exquisite cuts developed over time, the Portuguese cut diamond stands out for its exceptional faceting, old-world charm, and dazzling sparkle. But what exactly makes the Portuguese cut unique? Where does it come from, and why should you consider it for your engagement ring or jewelry collection?
This blog explores the history, characteristics, and significance of the Portuguese cut, blending expert insights from gemology with historical context.
What is a Portuguese Cut Diamond?
The Portuguese cut is a rare and intricate faceting style known for its high facet count—usually 85 or more—compared to the modern round brilliant cut, which has 57–58 facets. This additional faceting maximizes light dispersion, creating a stunning display of brilliance and fire.
Unlike modern cuts that prioritize weight distribution and standardized proportions, the Portuguese cut has a deep pavilion (bottom half of the diamond) and a rounded crown, which enhances its reflective properties. This cut is often found in antique jewelry and is highly sought after by collectors and vintage jewelry enthusiasts.
The Origins of the Portuguese Cut: Why is it Called "Portuguese"?
While the exact origins of the Portuguese cut remain uncertain, several historical connections suggest why this cut may bear Portugal’s name:
1. Connection to Brazilian Diamonds
During the 18th century, Brazil was the world’s leading source of diamonds. As a former Portuguese colony, Brazil supplied Portugal with a vast number of rough diamonds. Many of these stones were cut and polished in Portugal, where highly intricate faceting techniques were developed to maximize their brilliance. This could have led to the naming of the Portuguese cut.
2. Traditional Gem-Cutting Techniques
The Portuguese cut was likely crafted using a Jam Peg machine, an early faceting tool commonly used in Portugal, Brazil, and other European countries. This method involved using a wooden apparatus with holes at various angles to hold the gemstone, allowing cutters to create highly symmetrical facets. The precise craftsmanship associated with Portuguese lapidaries may have contributed to the naming of this unique cut.
3. Emphasis on Weight Retention
Historically, gem cutters prioritized preserving carat weight over achieving perfect symmetry. The Portuguese cut, with its deep pavilion and intricate faceting, aligns with this goal, ensuring that as much of the rough stone as possible was retained while enhancing its brilliance.
4. Royal & European Aristocracy Influence
Portugal, like many European nations, had a long history of royal jewelry collections and aristocratic gemstone commissions. The Portuguese royal family was known for owning lavish, highly faceted diamonds, making it possible that this cut was named after their preference for stones with superior brilliance.
Key Characteristics of the Portuguese Cut
A Portuguese cut diamond is instantly recognizable due to its intricate faceting and high brilliance. Here are the defining features of this unique cut:
💎 85+ Facets – Nearly 50% more than the round brilliant cut, creating exceptional sparkle.
💎 Deep Pavilion & Rounded Crown – This adds depth to the gem, making it appear almost three-dimensional.
💎 Superior Brilliance & Fire – The extra facets enhance light reflection, giving the diamond a breathtaking glow.
💎 Unique Vintage Appeal – Commonly found in antique jewelry, estate pieces, and custom cuts.
💎 Weight Retention – Unlike modern cuts that prioritize proportion, this cut preserves more of the original diamond weight.
Why Choose a Portuguese Cut Diamond for an Engagement Ring?
If you’re looking for a one-of-a-kind, heirloom-quality engagement ring, a Portuguese cut diamond offers beauty, rarity, and an enchanting history. Here’s why you should consider this exquisite cut:
1. Maximum Sparkle & Fire ✨
With 85+ facets, this cut outshines most modern diamond cuts. If you love a ring that sparkles intensely under any light, the Portuguese cut is a fantastic choice.
2. Vintage & Royalty-Inspired Elegance 👑
This cut is deeply rooted in European aristocracy and antique jewelry designs, making it perfect for those who appreciate historical charm. If you’re drawn to Victorian, Edwardian, or Art Deco styles, a Portuguese cut diamond fits seamlessly into that aesthetic.
3. Unique & Rare 🌍

The depth and brilliance of a Portuguese cut diamond symbolize the depth of commitment and the radiance of love. Its intricate facets represent the beautiful complexities of a lifelong relationship.
Challenges of the Portuguese Cut
While this cut is undeniably stunning, there are a few things to consider before making your purchase:
❌ Depth Can Make the Diamond Appear Smaller – Since more weight is held in the pavilion, a Portuguese cut diamond may look smaller than a modern cut of the same carat weight.
❌ Less Common & Harder to Find – Unlike round or princess cuts, the Portuguese cut is not mass-produced, so it may take more effort to source.
❌ Higher Cost for Custom Cuts – If you want a new Portuguese cut diamond, you may need to have it custom-cut, which can increase costs.
