Pink diamonds are priced differently—and far more aggressively—than yellow diamonds. Four main factors determine their value:

1. Color Intensity (The #1 Price Driver)

GIA grades pink diamonds as:

• Faint Pink
• Very Light Pink
• Light Pink
• Fancy Pink
• Fancy Intense Pink
• Fancy Vivid Pink
• Fancy Deep Pink / Fancy Deep Purplish Pink

In simple terms:

The stronger the pink → the rarer the diamond → the higher the price.

Mike Nekta’s Note: “Pink diamonds don’t follow standard logic. A small Vivid Pink can be worth more than a larger Fancy Pink. Color dominates everything.”

2. Origin — Especially Argyle (Major Price Impact)

Not all pink diamonds are created equal.

• Argyle Pinks (closed mine; Australia)
  → Premium of 30%–300% depending on color
  → Always more collectible
  → Prices are rising every year
• Non-Argyle Pinks (Russia, Africa, Brazil)
  → Still rare
  → Still valuable
  → But not the same collector prestige

Argyle stones come with separate origin documentation. If someone claims “Argyle Pink” without a certificate—it’s not Argyle.

3. Diamond Shape (How the Pink Reads in Real Life)

Best Shapes for Pinks (maximum saturation)

• Radiant Cut — amplifies color dramatically
• Cushion Cut — soft, romantic, strong color retention
• Pear Shape — tip intensifies color
• Oval — often appears more saturated than expected

More Difficult Shapes

• Emerald & Asscher — reveal everything; only strong colors look good
• Princess — decent color but less fire
• Round — tends to wash out pastels

Mike Nekta’s Note: “Shape can make the same stone look two intensities darker—or lighter.”

4. Modifiers (Secondary Hues)

Pink diamonds often have secondary tones:

• Purplish Pink (highly desirable)
• Brownish Pink (more affordable)
• Orangey Pink (rare and stunning)

The purest pinks demand the highest prices.

5. Carat Weight (Every Fraction Matters)

Pink diamonds jump in price dramatically at:

• 0.30 ct
• 0.50 ct
• 1.00 ct
• 1.50 ct
• 2.00+ ct (extremely rare)

Even a 0.20 ct size increase can double the price.

6. Clarity (Important but Secondary)

Clarity matters—but pink diamonds are graded more gently because inclusions are common.

Color > Clarity

A Fancy Vivid Pink SI2 can be more expensive than a Fancy Pink VS1.
