2025 is bringing some exciting new diamond shape trends that will turn heads and elevate your look. Let’s look at the diamond shapes making waves this year and how you can make them your own.

1. Baguette-Cut: Sleek and Modern

The Baguette cut is long and rectangular, offering sleek lines that make it a popular choice for those seeking a modern and minimalist aesthetic. Its elegant, subtle beauty pairs perfectly with other diamond shapes and enhances its surrounding pieces. A baguette-cut diamond necklace can effortlessly elevate a modern, chic look with understated luxury.

2. Half Moon Cut: A Unique and Elegant Shape

The Half Moon cut is one of the more unique and elegant shapes catching attention in 2025. Its distinctive semi-circular shape adds a touch of elegance and sophistication to any diamond necklace. 

Often combined with other stones, the Half Moon cut offers a sleek, modern aesthetic that stands out while maintaining a timeless charm.

Whether set in a solitaire or part of a multi-stone design, this shape will add an interesting visual element to your jewelry collection.

3. Heart Cut: Love at First Sight

For those seeking a truly romantic piece, the heart-cut diamond is a timeless symbol of love. While not as commonly seen in the mainstream, this shape is expected to have a resurgence in 2025. 

A heart-shaped diamond necklace is the perfect gift for a loved one, making it a meaningful and beautiful addition to any collection.

4. Kite Cut: Edgy and Artistic

The kite-cut diamond offers a bold, geometric appearance that is unlike most traditional cuts. Its pointed corners and sharp angles bring an edgy, artistic look to diamond necklaces.

The Octagon cut is a rare but sophisticated choice. Its eight sides create a mesmerizing reflection of light, making it a standout option for diamond necklaces in 2025. This shape is perfect for someone who wants a more unique yet elegant alternative to the more common cuts, bringing a timeless yet modern appeal to any design.

7. Oval Cut: Elegance in Elongation

The oval-cut diamond is an elegant, elongated shape that makes the diamond appear more prominent without the hefty price tag of a bigger carat. It combines the brilliance of a round diamond with the graceful length of an oval, offering a visually appealing option for those seeking sophistication. 

Oval-cut diamond necklaces are not only elegant but also versatile, complementing both casual and formal styles.

8. Round Cut: The Timeless Classic

The Round diamond continues to reign supreme, maintaining its place as the most popular choice for diamond necklaces. This shape is all about brilliance, with its 58 facets designed to reflect light from every angle. 

Its round, symmetrical form makes it perfect for any setting, whether you’re going for a single-stone pendant or a multi-diamond necklace design. The round-cut is a clear winner if you want a piece that will stand the test of time.

9. Pear Cut: The Best of Both Worlds

The Pear cut combines an oval’s elegance with a marquise’s sharp point, creating a graceful and bold shape. Known for its drop-like form, the pear cut makes a stunning focal point for a diamond necklace. It’s expected to remain a top choice for 2025, especially for classic solitaire designs or trendy multi-stone settings.

10. Princess Cut: Bold and Beautiful
