Our Most Loved Diamond Shapes
💎 Round – Classic and Brilliant
The round diamond is timeless, elegant, and designed for maximum sparkle. Its symmetrical cut reflects light beautifully, creating that dazzling brilliance that makes it the most popular choice. If you love classic, understated beauty, a round diamond will always be in style.
Our Tip:
- Choose an Ideal or Excellent cut for the best sparkle.
- Colour is less noticeable in a round diamond, so you have more flexibility with colour grades.
💎 Oval – Soft and Elegant
An oval diamond offers the brilliance of a round diamond but with a more elongated shape, which creates a flattering, slimming effect on the finger. Its larger surface area makes it look bigger than a round diamond of the same carat weight.
Our Tip:
- The ideal length-to-width ratio is between 1.30 and 1.45.
- Be mindful of the "bowtie effect", a dark shadow that can form across the middle of the diamond.
💎 Princess – Bold and Modern
The princess cut is known for its clean, sharp lines and brilliant sparkle. Its square shape gives it a contemporary feel while still maximizing fire and brilliance. It’s a popular choice for those who love modern elegance.
Our Tip:
- Choose a length-to-width ratio between 1.00 and 1.05 for a perfect square shape.
- A princess cut hides imperfections well due to its faceting.
💎 Emerald – Understated Glamour
The emerald cut is all about elegance and sophistication. Its long, step-cut facets create a "hall of mirrors" effect, highlighting the diamond’s clarity rather than sparkle. It’s perfect for someone who loves vintage charm with a modern twist.
Our Tip:
- The ideal length-to-width ratio is between 1.30 and 1.40.
- Choose a higher clarity grade, as inclusions are more visible in an emerald cut.
💎 Cushion – Soft and Romantic
With its rounded corners and pillow-like shape, the cushion cut has a soft, romantic feel. Its larger facets enhance the diamond’s brilliance, giving it a beautiful balance of sparkle and softness.
Our Tip:
- For a square cushion, aim for a 1.00 to 1.05 ratio.
- For a more elongated look, choose a ratio of 1.10 or higher.
💎 Marquise – Dramatic and Eye-Catching
The marquise cut is known for its long, pointed shape, which creates a dramatic look while making the finger appear longer and slimmer. Its unique shape maximizes the diamond's carat size, making it appear larger than it is.
Our Tip:
- The ideal length-to-width ratio is between 1.75 and 2.25.
- Symmetry is key to ensuring the diamond sits evenly on your finger.
💎 Pear – Graceful and Unique
The pear cut, or teardrop shape, combines the round and marquise cuts for a soft yet striking look. Its elongated shape is both delicate and distinctive, creating a flattering effect on the hand.
Our Tip:
- The most flattering length-to-width ratio ranges from 1.45 to 1.75.
- Ensure the point is centred and the curves are symmetrical for a balanced look.
💎 Radiant – Brilliant and Modern
The radiant cut combines the sparkle of a round cut with the elegance of an emerald cut. Its cropped corners and 70 facets give it exceptional brilliance, making it a dazzling choice for someone who wants sparkle and sophistication.
Our Tip:
- For a square shape, choose a ratio of 1.00 to 1.05.
- For a rectangular shape, aim for a ratio of 1.25 to 1.50.
💎 Asscher – Vintage and Sophisticated
The Asscher cut is similar to the emerald cut but with a square shape and more facets, creating a deep, captivating sparkle. Its step-cut design gives it a vintage, Art Deco feel.
Our Tip:
- The ideal length-to-width ratio is between 1.00 and 1.05.
- Choose a higher clarity grade, as inclusions are more visible in step-cut diamonds.
💎 Trilliant – Bold and Striking
The trilliant cut is triangular and designed to maximize light reflection. Its bold shape makes it stand out, whether used as a centre stone or as a side stone in a more elaborate setting.
Our Tip:
- A 1:1 length-to-width ratio creates the perfect triangular shape.
- Choose a depth percentage between 32% and 42% for the best sparkle.
💎 Heart – The Ultimate Symbol of Love
A heart-shaped diamond is a romantic and symbolic choice. Its distinctive shape requires precise symmetry and expert craftsmanship to capture its true beauty.
Our Tip:
- Symmetry is key. The wings should be balanced, and the point should be sharp and defined.
- A length-to-width ratio between 0.90 and 1.10 creates a balanced heart shape.
