Understanding Diamond Cuts — It’s More Than Shape

Most people think of shapes like round, oval, princess, etc. when they hear the term "diamond cut." However, "cut" in the diamond industry refers to a diamond's level of craftsmanship, which has a direct impact on its:

     ☆How much it sparkles in the light is its brilliance.
     ☆ How fire divides light into rainbow hues
     ☆ The way light dances as the diamond moves is called scintillation.
     ☆ Symmetry, polish, and proportions

A diamond that has been well cut will look brighter, cleaner, and bigger than one that is poorly cut, yet the same size. And as far as pricing goes, cut reigns supreme.

What Makes a Diamond Cut More Expensive?💸

Not all diamond cuts are equal in terms of production, craftsmanship, and demand. A number of factors decide the cost of a particular cut:

1. Wastage of Rough Diamond
Certain cuts waste more of the rough material, i.e., more of the original diamond is discarded in the process of shaping it. The greater the wastage, the more the cost.

2. Popularity & Demand
Popular cuts such as round brilliant cost more due to high demand, thereby increasing prices.

3. Cut Complexity
Certain diamond cuts take more time, effort, and tools to achieve perfection. The higher the labor expense, the higher the price of the diamond.

4. Light Performance
Diamonds that create sparkle and brilliance are worth more. People are willing to pay more for diamonds that "dance in the light."

Diamond Cuts Ranked by Price (From Most to Least Expensive)🔝

1. Round Brilliant Cut – The Classic Queen💎

✅ Most expensive cut on the market
💡Provides the most brilliance because of 58 facets
🔧Difficult to cut and polishes off as much as 60% of the rough diamond
📈Most in demand worldwide (over 70% of diamonds sold are round)

Why it's expensive:
The high demand, combined with precision needed and coarse wastage, make round brilliant diamonds the most expensive of them all. 

2. Princess Cut – The Modern Icon

✅ Rectangular or square shape with sharp corners
💡 Good glitter but less so round
🔨 Less wastage than round, so a little less expensive

Why it's costly:
It is the most selling fancy cut and provides tremendous brilliance at less price than round and is therefore an excellent second choice.

3. Cushion Cut – The Vintage Darling

✅ Soft edges and rounded corners
💡 Good brilliance with an old-world charm
📐 Greater depth in the cut, sometimes appears smaller face-up

Why it's mid-range:
Cushion cuts are romantic and sweet, but less wasteful and easier to make than round or princess cuts.

 4. Oval, Pear & Marquise Cuts – The Illusion Artists

✅ Long shapes that make fingers appear longer
💡 Better brilliance and greater face-up appearance
🪞 Make diamond appear larger than it actually is

Why they're budget-friendly:
They save more rough diamond and look bigger, providing better value per carat. They're distinct but not as popular as round or princess.

5. Emerald & Asscher Cuts – The Sophisticated Minimalists

✅ Rectangular or square step cuts
🔍 Display clarity rather than sparkle
🧩 Need to use superior diamonds with fewer inclusions

Why they are less expensive:
While sophisticated, they are less sparkly, and customers tend to prioritize brilliance. Demand is moderate, so prices are affordable.

Why the Round Brilliant Cut Is the Most Expensive👑

At San Liora, we get asked frequently — "Why is the round diamond always the most expensive?" The reason is the flawless combination of science, art, and demand. The round brilliant cut is more than a shape — it's a work of geometric art, honed over centuries to give maximum sparkle and refract light better than any other cut.

Let's take a closer look at the reasons behind its premium price:

1. Precision Craftsmanship & Complex Cutting Process

The round brilliant cut contains 58 carefully computed facets, all carefully angled to reflect as much light as possible.
This cut adheres to precise proportions developed using scientific modeling, which necessitates:

• High-end cutting technology
• Highly trained artisans
• Massive amounts of labor time

Even the smallest miscalculation of angle or symmetry can diminish brilliance, so each stone has to be cut perfectly. This not only adds production time but also labor cost, directly affecting price.

2. High Rough Diamond Wastage

Slicing a round diamond causes tremendous loss of material—60% of the original rough diamond is spent to obtain that perfect circularity and facet pattern.

Let's compare:

What you're really paying for is not only the diamond you receive, but also that considerable portion that was skillfully removed.

3. Unmatched Brilliance & Sparkle

The round brilliant cut is designed for light. Due to its symmetrical construction and 58 facets, it provides:

• Highest brilliance (return of white light)
• Highest fire (dispersion of rainbow light)
• Best scintillation (sparkle as it moves)

No other shape can match the optical performance of a well-cut round diamond. That brilliance is what makes it irresistible—and worthy of the premium.

4. Timeless Popularity & Market Demand

More than 70% of all diamond engagement rings sold worldwide have a round brilliant cut. Its timeless, universal allure has endured across trends, cultures, and generations.

Because it's so universally popular:

• Supply chains are optimized for the round cut
• Marketers emphasize this cut
• Resale value endures over time

Demand is high + supply is constrained = higher price.

5. Ideal for Diamond Grading & Certification

Round diamonds are simpler to assess using standard grading equipment, particularly brilliance, cut grade, and symmetry.

GIA (Gemological Institute of America) only offers cut grades for round brilliant diamonds. This openness enhances trustfulness — and hence price — because buyers feel more assured about what they're spending.

6. Universally Flattering

Round diamonds provide an even, symmetrical appearance that complements every hand shape. They go with:

• Solitaire settings
• Halo designs
• Vintage and contemporary bands

Such flexibility contributes to their appeal for everyone — they fit any style and occasion, from understated elegance to glamorous drama.
