The Portuguese cut gives your steak more depth, texture, and visual appeal than most cuts do. At Ouros Jewels, you can find this expertly cut stone in wonderful lab-grown varieties that are also sustainable. 

We will look at the reasons the Portuguese cut oval diamond is drawing so much attention. 

What Is a Portuguese Cut Diamond?

Portuguese cut diamonds are unique gems with 161+ facets twice as many as a standard round diamond. These facets create a bright, fiery sparkle. Originally used for gems like topaz, this cut now shines in lab-grown diamonds and mined diamonds. Available in shapes like round, oval, and antique, Portuguese cuts are perfect for vintage jewelry lovers.

Historically made for stones such as topaz and amethyst, the technique is now growing in popularity for lab-grown diamonds and regular diamonds because of recent cutting progress. If the ring is shaped like an oval, the result is truly remarkable.

Why Portuguese Cut Diamonds Shine Brightly

Portuguese cut diamonds sparkle in round, oval, and many antique shapes. Their 161+ facets reflect light for a dazzling look. Round shapes offer classic elegance, ovals make fingers look slimmer, and antique shapes add vintage charm, making this cut perfect for unique engagement rings or custom jewelry.

Oval Portuguese cuts add both drama and subtlety to diamonds, which makes them a great match for people who prefer something different, but not too daring.

Lab-grown diamonds can be identical in makeup, appearance, and light properties to natural diamonds. The Portuguese cut stands out with unmatched sparkle and vintage flair. Let’s compare it to popular styles to see how it holds up in beauty and appeal. 

Let’s compare it to popular styles:

Cut Type No. of Facets Sparkle Quality Ideal For
Portuguese Cut 161+ High brilliance and fire Vintage-modern lovers, luxury collectors
Round Brilliant 57–58 Bright, balanced sparkle Timeless elegance, classic engagement rings
Rose/Mogul Cuts 12–24 (Rose), Multi-ring (Mogul) Subtle surface shimmer Minimalist antique looks, romantic settings
Old Mine Cut 58 Soft, romantic glow Antique-inspired or heirloom jewelry

Understanding the Craftsmanship 

Cutting a Portuguese diamond is not easy. It requires:

  • Advanced skill
