Are Round Diamonds More Valuable Than Marquise Diamonds? What Buyers Should Know
During engagement season, one of the most common questions buyers ask is whether round diamonds are more valuable than marquise diamonds. The short answer is yes—round diamonds often command higher prices. But value in fine jewelry is not defined by price alone. Shape, brilliance, finger coverage, and personal style all play an important role in determining what feels most valuable to the wearer.
Understanding why these two shapes differ in price and presence can help you make a confident, informed decision before proposing.
Why Round Diamonds Are Typically More Expensive
Round brilliant diamonds dominate the engagement ring market. Their popularity, cutting complexity, and light performance all contribute to higher pricing.
Market Demand
Round diamonds account for more than half of all engagement ring sales in the U.S. This sustained demand naturally increases their market value.
Cutting Complexity & Yield
Round diamonds are cut to exacting standards designed to maximize brilliance and fire. Achieving ideal proportions often means sacrificing more rough diamond material during cutting, which increases cost.
Brilliance & Light Performance
The round brilliant cut is engineered for optimal light return. Its symmetry and facet structure create unmatched sparkle, making it the benchmark for brilliance in fine jewelry.
Because of these factors, round diamonds typically carry a price premium per carat.

Why Marquise Diamonds Offer Exceptional Visual Value
While marquise diamonds are usually priced lower than rounds, they offer a different kind of value—one rooted in visual impact and elegance.
Maximum Finger Coverage
Marquise diamonds are elongated, creating the illusion of a larger stone. A marquise can appear significantly bigger than a round diamond of the same carat weight due to its surface area.
Elegant, Lengthening Effect
The tapered shape visually elongates the finger, making it especially flattering for many hand shapes.
Lower Cost Per Carat
Because marquise diamonds are in lower demand and yield more usable rough material during cutting, they are often more budget-friendly—allowing buyers to go larger without increasing cost.

Brilliance, Demand, and Cutting Differences
Round diamonds excel in brilliance due to their precise facet arrangement. Marquise diamonds sparkle differently, offering a mix of brilliance and elegance rather than pure fire.
Round Diamonds
- Maximum sparkle and symmetry
- Highest demand and resale recognition
- Ideal for classic, timeless designs
Marquise Diamonds
- Softer brilliance with dramatic shape appeal
- More complex cutting to maintain symmetry and avoid bow-tie effects
- Unique and expressive silhouette
Both shapes require expert cutting, but marquise diamonds demand a skilled eye to ensure balance and light performance, especially at the tips.
Choosing Value Based on Lifestyle and Personal Style
True value isn’t always about choosing the most expensive option, it’s about choosing the shape that fits your lifestyle and aesthetic.
Choose a round diamond if you value:
- Maximum brilliance
- Timeless appeal
- Traditional luxury
Choose a marquise diamond if you value:
- Larger visual presence
- Elegant, elongated shapes
- Distinctive, fashion-forward design
Both shapes can be extraordinary when paired with thoughtful setting design and expert curation.
