Diamond Shape Comparison

By Mike Nekta
25 Years in the NYC Diamond District

“Most people choose diamond shapes based on style — but with fancy color diamonds, shape controls how strong the color appears. Pick the wrong cut, and you lose 40–70% of the color you paid for.”

Why People Trust Me With Fancy Color Diamonds

For 25 years, I’ve specialized in natural fancy color diamonds — comparing shapes, color intensities, and light performance in real daylight, not showroom tricks.

I’ve handled thousands of natural yellow, pink, blue, and other rare colors. I’ve seen how dramatically shape impacts:

  • color strength
  • saturation
  • brilliance
  • value
  • rarity
  • face-up size

Here’s the reality that most buyers don’t know:

Two diamonds of the same color grade can look completely different depending on the cut.

My job is simple:

  • Guide clients to the shape that maximizes color
  • Protect them from shapes that wash color out
  • Show stones side-by-side in real daylight

This guide reveals the truth — not the marketing version.

Diamond Shape Impact at a Glance

Shape affects:

  • How intense the color looks
  • How the light travels through the stone
  • How large the diamond appears
  • How rare the shape is in fancy colors
  • How well color holds at different carat weights

Mike Nekta’s Note: “Color behaves differently in every shape. Some shapes make color explode — others dilute it instantly.”

How Shape Affects Fancy Color Diamonds

Fancy color diamonds rely on light retention rather than brilliance.

Shapes that trap light show stronger color.
Shapes that release light wash color out.

That’s why certain cuts dominate the fancy color world.

Let’s compare them.

Best Shapes for Fancy Color Diamonds (Ranked)

1. Radiant Cut – The Color Maximizer

  • Strongest face-up color retention
  • Brilliant and fiery
  • Preferred by cutters for yellow, pink & blue
  • Most common shape for strong intensities

Why: Deep pavilions concentrate color.

Mike Nekta’s Note: “If someone wants the strongest color possible, I show radiant cuts first.”

2. Cushion Cut – Rich, Velvety Color

  • Similar performance to radiant
  • Softer, more vintage style
  • Excellent for pinks and yellows
  • Rare for blues

Why: Rounded edges help “hold” color.

3. Pear Shape – Elegant with Strong Color Zones

  • Great for yellows
  • Very flattering on the hand
  • Point concentrates color
  • More face-up area than radiants

Why: Shape naturally creates a “hot spot” of deeper color.

4. Oval – Bright and Open Looking

  • Good for yellow and champagne tones
  • Helps appear larger per carat
  • Color slightly lighter than radiant/cushion

Why: Spreads color across a larger surface.

5. Marquise – Vibrant and Dramatic

  • Good at amplifying yellow
  • Rare in strong pinks
  • Very limited supply

Why: Long shape intensifies color at the tips.

Shapes That Are Rarely Used for Fancy Colors

6. Emerald Cut – The Color Reducer

  • Most unforgiving shape
  • Shows inclusions clearly
  • Cannot retain strong saturation

Why: Large open facets leak light — and color.

Mike Nekta’s Note: “Emerald cuts look incredible in white diamonds — but they wash color out. I only recommend them for very strong natural colors.”

7. Asscher Cut – Similar to Emerald

  • Step-cut
  • Often loses color
  • Works only with extremely strong stones

Why: They prioritize clarity over color.

8. Round Brilliant – Almost Never for Fancy Colors

  • Maximizes brilliance
  • Minimizes color
  • Extremely rare in strong fancy color grades

Why: Round cuts reflect too much white light.

Rarity Levels By Shape (Fancy Color Diamonds)

Shape Availability in Natural Fancy Colors Notes
Radiant High Most common in strong colors
Cushion High Ideal for pink & yellow
Pear Medium Popular for yellows
Oval Medium Great spread
Marquise Low Limited production
Emerald Very Low Rare in intense/vivid colors
Asscher Very Low Mostly lighter tones
Round Extremely Rare Hard to retain color

Summary: The more brilliant the cut, the harder it is to keep color.

Which Shape Makes Color Look Strongest?

Top Performer: Radiant

Runner-Up: Cushion

Directional Intensifiers: Pear & Marquise

Color Reducers: Emerald, Asscher, Round

Mike Nekta’s Note: “The right shape can make a Fancy look Intense — or make an Intense look Fancy Light.”

I flew to NYC specifically to visit Mike’s store. It was our 30th wedding anniversary and I wanted to purchase from someone I knew I could trust. His selection is the best there. He will work with you to make sure that you walk away very happy with your purchase. I will definitely be making many more trips to buy from him.
