Choosing the perfect diamond begins with selecting the right shape. While many people use the terms diamond shape and diamond cut interchangeably, they refer to two different characteristics. Diamond shape describes the outline of the stone, while cut refers to how well the diamond has been faceted to maximize brilliance.

At Jacob Mercari, we offer both natural and lab-grown diamonds in a wide variety of shapes, helping you create a custom engagement ring that perfectly reflects your style and personality. Whether you prefer timeless elegance or modern sophistication, understanding the differences between diamond shapes will help you make a confident decision.

Round Brilliant Diamond

Oval Diamond

Oval diamonds have become one of today's most sought-after choices. Their elongated shape creates the illusion of longer, slimmer fingers while appearing larger than many other diamonds of the same carat weight.

Which Diamond Shape Sparkles the Most?

If brilliance is your top priority, these shapes typically offer the most sparkle:

1. Round Brilliant

2. Oval

3. Radiant

4. Princess

5. Cushion

Step-cut diamonds such as Emerald and Asscher offer a different kind of beauty, showcasing clarity and elegant flashes of light rather than intense sparkle.

Which Diamond Shape Looks the Largest?

Some diamond shapes appear larger than others, even when they share the same carat weight.

Shapes that often look larger include:

• Oval

• Marquise

• Pear

• Emerald

• Radiant

Their elongated proportions create a greater surface area, making them appear larger on the finger.

Natural vs. Lab-Grown Diamonds

Every diamond shape is available in both natural and lab-grown diamonds. Both offer the same physical, chemical, and optical properties, with the primary differences being their origin and price.

At Jacob Mercari, we offer carefully selected natural and lab-grown diamonds in every popular shape, allowing you to create a ring that fits both your style and your budget.
