Black, Grey & Salt and Pepper Diamonds: Types Explained

1. What Are Fancy-Color and Inclusion-Rich Diamonds?

Traditional diamonds are valued for the “Four Cs”: Cut, Color, Clarity, and Carat. Inclusions—tiny imperfections formed over billions of years—are typically seen as flaws.

But in black, grey, and salt and pepper diamonds, these inclusions are the main attraction.

These diamonds are:

• More organic-looking

• Uniquely patterned

• Affordable alternatives to classic white diamonds

• Ethically appealing, as they reduce wastage of mined stones

• Growing in popularity, especially among millennials and Gen Z

Quick note: these diamonds are real — they are crystallized carbon like any other diamond. Their appeal lies in uniqueness, affordability, and the natural story etched into each stone.

2. Black Diamonds: Meaning, Types & Features

Black diamonds are bold, dramatic, and perfect for people who want a non-traditional look.

What Makes a Diamond “Black”?

Black diamonds contain large numbers of graphite, hematite, or fractures that give them their dark appearance. They do not sparkle the same way white diamonds do—instead, they have a beautiful, glossy, metallic sheen.

Types of Black Diamonds : 

1. Natural Black Diamonds

• Formed naturally deep within the earth
• Uniformly black due to heavy concentrations of inclusions
• More rare than treated black diamonds
• Highly durable because inclusions are evenly distributed
• Color: Opaque black
• Sparkle: Minimal, surface luster
• Price: Higher than treated black diamonds

2. Treated Black Diamonds

• Created from low-clarity white diamonds
• Exposed to high heat or radiation to darken the entire stone
• Popular for fashion jewelry due to affordability
• Color: Jet black
• Sparkle: Glossy but not brilliant
• Price: Most affordable of the three diamond types

✔ Pros

• Bold and striking appearance

• Affordable

• Perfect for men’s rings

• Durable for daily wear

✘ Cons

• No fire or brilliance

• Treated diamonds may chip more easily

• Hard to grade traditionally

3. Grey Diamonds: A Rising Favorite

Grey diamonds offer a softer alternative: they keep some brilliance while giving a smoky, misty color. The grey tone typically results from trace elements or structural variation within the crystal. Grey diamonds have gained massive popularity for minimalist engagement rings. Their stormy, moody tone makes them visually mesmerizing.

Grey diamonds range from pale silver to deep charcoal and often show sparkle more than black or salt & pepper stones.

What Makes Grey Diamonds Unique?

Grey diamonds get their color from hydrogen or boron impurities. They may have tiny inclusions, giving them character without overpowering the stone.

Color Range

• Light silver grey

• Steel grey

• Charcoal grey

• Smoky grey

5. Black vs Grey vs Salt & Pepper: Key Differences

6. Pricing & Value

Pricing depends on rarity, treatment, cut and size. Broadly:

• Treated black diamonds: lowest price per carat
• Natural black diamonds: mid-range
• Grey diamonds: medium–high
• Salt & pepper diamonds: medium — high depending on pattern uniqueness

Salt & pepper diamonds often offer the best value for uniqueness. If you want a one-of-a-kind stone without the price of a flawless white diamond, they are an excellent choice.

7. Durability & Daily Wear

All diamonds score 10 on the Mohs scale for hardness, but inclusions and internal fractures affect toughness (resistance to chipping).

• Black diamonds: Natural black diamonds are durable; treated ones can be more brittle.
• Grey diamonds: Generally very suitable for everyday wear due to fewer major inclusions.
• Salt & pepper diamonds: Durable but inspect for large feathers or cleavages — choose protective settings when in doubt.

8. Best Cuts & Settings
