Choosing a diamond shape is one of the most personal decisions in the engagement ring process. While there are many beautiful options, oval and marquise diamonds continue to stand out in 2026 as two of the most requested shapes for custom engagement rings. Both are elegant, elongating, and visually striking—but they offer very different personalities.
At J&M Jewelry, we’re seeing growing interest in both shapes as couples look for rings that feel distinctive, flattering, and timeless. Below, we break down why oval and marquise diamonds are trending in 2026, how they differ, and how to decide which one fits your style best.

Why Oval and Marquise Diamonds Are Trending in 2026
Engagement ring trends in 2026 are all about individuality and intentional design. Buyers want shapes that feel unique without being overly trendy—and both oval and marquise diamonds strike that balance perfectly.
Oval diamonds appeal to those who love classic elegance with a modern edge.
Marquise diamonds attract buyers looking for a bold, statement-making ring with vintage influence.
Customization plays a major role in their popularity. These shapes look especially striking when paired with custom band widths, unique settings, or lab-grown diamonds—making them ideal for bespoke designs.
Oval Diamonds: Soft Elegance with Everyday Wearability
Why Choose an Oval Diamond Ring?
Oval diamonds are essentially elongated round brilliants, designed to maximize sparkle while offering a more modern silhouette.
Key characteristics:
Brilliant faceting for strong light return
Elongated shape that makes fingers appear longer and slimmer
Rounded edges that reduce the risk of chipping
Often appear larger than round diamonds of the same carat weight
In 2026, oval diamond engagement rings remain one of the most versatile choices, working beautifully in solitaires, halos, and minimalist settings.
Consideration:Some oval diamonds can show a “bow-tie” shadow across the center. At J&M Jewelry, careful stone selection and expert cutting help minimize this effect.
Marquise Diamonds: Bold, Dramatic, and Distinctive
Why Choose a Marquise Diamond Ring?
Marquise diamonds are defined by their pointed ends and dramatic length, creating one of the most striking silhouettes in fine jewelry.
Key characteristics:
Distinctive shape with strong visual presence
Elongates the finger more dramatically than most cuts
Maximizes apparent size per carat
Pairs beautifully with vintage and custom designs
Marquise diamond engagement rings are seeing renewed popularity in 2026 as vintage-inspired and non-traditional styles continue to rise.
Consideration: Because of the pointed tips, marquise diamonds benefit from protective settings such as V-prongs or halos—something our custom design team always accounts for.

Oval vs. Marquise: How to Decide
When choosing between an oval or marquise diamond, consider the following:
Lifestyle: Oval diamonds are slightly more forgiving for daily wear.
Style preference: Ovals feel soft and classic; marquise feels bold and architectural.
Finger appearance: Both elongate the finger, but marquise offers a more dramatic effect.
Setting vision: Ovals suit nearly every style, while marquise shines in custom or vintage-inspired settings.
Neither choice is “better”—the right shape is the one that reflects your personality and how you want your ring to feel every day.
