Choosing the right diamond shape is one of the most exciting parts of finding your dream engagement ring.
At Tang&Co, we believe the perfect shape reflects not just your style — but your story.
Whether you're drawn to timeless classics or modern silhouettes, understanding the different diamond cuts will help you make a choice you’ll love forever.
Here’s your complete guide to the most popular diamond shapes and how to choose the one that’s right for you.
1. Round Brilliant Cut
The round brilliant cut diamond is the most popular and iconic of all diamond shapes.
Known for its exceptional sparkle, it’s timeless, elegant, and always in style.
-
Best for: Classic romantics and those who love maximum brilliance.
-
Tip: Round diamonds are the most versatile and work beautifully in solitaires, halos, and pavé settings.
2. Oval Cut
The oval diamond offers a flattering, elongated look that makes fingers appear slender.
It delivers incredible sparkle while offering a modern twist on the classic round.
-
Best for: Those who love a blend of tradition and trend.
-
Tip: A well-proportioned oval minimizes the “bow-tie effect.”
3. Cushion Cut
The cushion-cut diamond features soft, rounded corners and a pillow-like shape.
Loved for its vintage charm and romantic sparkle, it's a favorite among those seeking something timeless yet distinctive.
-
Best for: Lovers of vintage glamour and soft brilliance.
-
Tip: Choose a cushion with a brilliant cut pattern for maximum sparkle.
4. Emerald Cut
The emerald cut diamond is known for its clean lines and sophisticated, mirror-like flashes of light rather than fiery sparkle.
-
Best for: Minimalists and lovers of old-Hollywood glamour.
-
Tip: Look for a higher clarity grade, as the open facets show inclusions easily.
5. Princess Cut
Sharp, modern, and full of brilliance, the princess-cut diamond is the go-to for those seeking a bold, contemporary style.
-
Best for: Those who love geometric, edgy designs.
-
Tip: Opt for a setting that protects the corners, which can be more fragile.
6. Pear Cut (Teardrop)
The pear-shaped diamond offers a unique blend of elegance and drama with its teardrop silhouette.
-
Best for: Brides who want something distinctive and eye-catching.
-
Tip: Ensure symmetry — a well-shaped pear should look balanced on both sides.
7. Radiant Cut
The radiant cut diamond blends the clean lines of an emerald cut with the brilliance of a round cut, offering a sparkling rectangular or square look.
-
Best for: Those who love bold, vibrant sparkle with a modern edge.
8. Marquise Cut
The marquise diamond has an elongated, pointed shape that maximizes surface area, creating the illusion of a larger diamond.
-
Best for: Those looking for a bold, royal-inspired ring.
-
Tip: A marquise cut elongates the finger beautifully.
9. Heart Cut
The heart-shaped diamond is the ultimate symbol of love and romance.
Its distinctive silhouette makes it a unique and deeply meaningful choice for an engagement ring.
-
Best for: Romantic souls who want their love story reflected in their ring.
-
Tip: Symmetry is key — ensure the heart shape is even and well-proportioned.
10. Asscher Cut
The Asscher cut diamond is a vintage-inspired shape featuring a square form with deeply trimmed corners and step-cut facets.
It exudes sophistication, offering a stunning hall-of-mirrors effect.
-
Best for: Lovers of Art Deco style and structured elegance.
-
Tip: Like emerald cuts, Asscher cuts highlight clarity — choose a high clarity grade for the best appearance.
How to Choose the Perfect Diamond Shape
When selecting a diamond shape for your engagement ring, consider:
-
Your style: Classic, modern, vintage, artistic?
-
Finger shape: Some cuts (like oval, pear, marquise) elongate the hand beautifully.
-
Lifestyle: More durable cuts (like round and cushion) are ideal for daily wear.
-
Personal meaning: Some shapes, like heart diamonds, carry symbolic significance.
There is no one-size-fits-all answer — the best diamond shape is the one that captures your heart.
