A diamond's "shape" greatly changes its overall impression. Learn the characteristics of representative shapes to find the perfect stone for your taste. For the evaluation criteria of brilliance, please also see our 4C Guide.
Representative Shapes
- Round Brilliant: The most popular shape. Strong brilliance and timeless beauty.
- Princess: Square-shaped, sharp, and modern impression.
- Oval: Elongated shape that makes fingers look longer.
- Pear Shape / Marquise: Distinctive and glamorous.
- Cushion / Emerald: Soft / classical atmosphere.
Points for Choosing
We recommend choosing based on the impression you want to create — round if you prioritize brilliance, oval if you want individuality or to make your fingers look longer. Even with the same carat weight, the appearance changes depending on the shape, so compare them in person.

Compatibility Between Shape and Setting
The setting that suits a stone (the number of prongs and surrounding design) varies depending on the shape. Please consider the setting design together by browsing our Engagement Ring Collection.
If You're Unsure
Price Trends by Shape
Round brilliants are in high demand, so they tend to be slightly more expensive even under the same 4C conditions. On the other hand, fancy shapes such as oval and pear shape can sometimes be more affordable, allowing them to appear larger even within the same budget. Please check with the store for detailed pricing.
Settings That Suit Each Shape
- Round: A versatile type that pairs well with any setting
- Oval: A setting that emphasizes the vertical line, making fingers look longer
- Princess: Sharp, linear designs
Popularity Trends
Among first-time buyers, round is the most popular choice. For those who want to express individuality or make the stone appear larger within the same budget, fancy shapes like oval are also gaining popularity.
If you're unsure as a first-time buyer, the classic round shape is a safe choice with little room for regret. Those wanting to express individuality should also consider oval or pear shape.
