Natural diamonds are timeless treasures formed deep beneath the Earth’s surface over billions of years. This guide covers how they’re formed, how they compare to lab diamonds, pricing, color grading, and why natural diamonds in Canada remain a top choice for engagement rings, heirloom pieces.
Natural diamonds are crystallized carbon gemstones created naturally under extreme heat and pressure in the Earth’s mantle. Unlike lab grown diamonds, which are man-made in weeks, natural diamonds are shaped by nature over billions of years — making each stone one-of-a-kind.
These rare gems symbolize authenticity and hold significant emotional and market value, especially when GIA certified.
Natural diamonds form 150–200 kilometers below the Earth’s surface under intense pressure (over 725,000 psi) and temperatures above 1,200°C. Over 1 to 3.5 billion years, carbon atoms crystallize into diamond structures. Volcanic eruptions eventually bring them to the surface via kimberlite pipes, where they are mined.
Most natural diamonds are between 1 and 3.5 billion years old—older than most life on Earth. Owning a natural diamond means carrying a piece of geological history, making them perfect for heirlooms or meaningful gifts.
In their raw state, natural diamonds can be opaque or transparent, with a rough, frosted surface. Once professionally cut and polished, they reveal unmatched brilliance, fire, and sparkle — especially in cuts like the round brilliant with up to 58 facets.

The price depends on the 4 Cs:
Carat: Weight of the diamond
Cut: Precision affects brilliance
Color: Rated D (colorless) to Z (light yellow/brown)
Clarity: Degree of internal inclusions
Prices range from $1000 CAD per carat for commercial-quality stones to $20,000+ CAD per carat for flawless, colorless diamonds.
Only 0.1% of mined diamonds are naturally colored. Their hues come from trace elements or crystal structure distortions, making them extremely collectible.
Natural Black Diamonds – Opaque and dramatic, formed with graphite inclusions
Natural Blue Diamonds – Boron gives them a rare blue hue
Natural Pink Diamonds – Lattice distortion creates a rosy tone; very valuable
Natural Green Diamonds – Caused by radiation exposure during formation
Natural Yellow Diamonds – Colored by nitrogen, offering warmth and affordability
The Gemological Institute of America (GIA) grades diamonds from D (colorless) to Z (light yellow or brown). This scale affects both appearance and price.
