The New Modern: How Oval, Pear, and Marquise Cuts Took Over Lab Diamond Fashion

For a century, the Round Brilliant Cut was the undisputed default. It was the safe choice. It was the standard. If you closed your eyes and imagined a diamond, you imagined a circle.

But in the last few years, a seismic shift has occurred in the jewelry world. We have entered the era of "The New Modern."

At OBY Jewelry, we have watched the tide turn. The modern collector is no longer satisfied with "standard." She wants silhouette. She wants geometry. She wants a stone that does more than just sparkle—she wants a stone that speaks.

This is how Oval, Pear, and Marquise cuts—collectively known as "Fancy Cuts"—took over the conversation, and why they are the smartest choice for your next Lab Diamond investment.

The "Elongated" Effect: Why Shape Matters

The sudden obsession with elongated diamond jewelry isn't just a random trend; it is rooted in visual psychology and flattering aesthetics.

Round diamonds are symmetrical, but they don't interact with the body's natural lines. Elongated shapes, however, work with you. They draw the eye vertically, creating an optical illusion that makes fingers look longer, slimmer, and more elegant. They also tend to look significantly larger than round diamonds of the same carat weight because their surface area is spread out.

1. The Oval: The New Icon

If there is one shape that defines the current lab diamond oval trend, it is this one. The Oval cut has effectively dethroned the Round cut as the "It Girl" of the 2020s.

It bridges the gap between classic and contemporary. It has the intense brilliance of a round diamond (so you don't lose any sparkle) but possesses a lengthening quality that feels thoroughly modern. It is the choice for the woman who wants tradition, but with a twist.

2. The Marquise: The Bold Architect

For a long time, the Marquise cut was considered "vintage." Now, it is the sharpest tool in a fashion-forward woman's arsenal. With its pointed ends and curved body, the Marquise maximizes carat weight better than any other shape.

At OBY, we love using this cut to create architectural, statement pieces. Just look at our Marquise Dome Ring.

In this design, the sharp, icy geometry of the Marquise Lab Diamond cuts through the soft, heavy volume of the Gold Vermeil dome. It’s a study in contrasts. It feels powerful. It’s a shape that says you aren't afraid to take up space.

We also utilize this shape for texture in our Marquise Bezel Chains, proving that this dramatic cut can also be delicate and layerable.

3. The Pear: The Organic tear

While pear shape earrings fashion is having a major moment on the red carpet, we believe this shape truly shines when it sits against the skin.

The Pear (or Teardrop) is unique because it is asymmetrical. It has a round bottom and a pointed top, mimicking the shape of a drop of water. This gives it a fluid, organic feel that rigid square cuts lack.

Our Dewdrop Diamond Silver Necklace captures this perfectly. By using a Pear-shaped Lab Diamond, the necklace feels like a captured moment of rainfall. It elongates the neck and offers a sophisticated "V" shape that is incredibly flattering on the décolletage.

Breaking the "Round" Habit

Why are we seeing this takeover now? Because Lab Diamonds allow for experimentation.

In the past, finding a high-quality fancy cut was difficult and expensive. But with OBY’s premium Lab Diamonds, you get perfect symmetry and clarity in these complex shapes without the astronomical markup.

It is time to think outside the circle. Whether you choose the fluidity of the Pear, the sharpness of the Marquise, or the elegance of the Oval, choosing a fancy cut is the easiest way to update your look.

Welcome to the New Modern.
