Natural diamonds are far more than just dazzling stones — they are ancient wonders shaped by the Earth’s most powerful forces.
At Tang&Co, we honor the legacy and beauty of natural diamonds, offering gems that embody history, rarity, and eternal elegance.
Let’s explore where natural diamonds come from, how rare they truly are, and why they continue to be a symbol of lasting love.
What Is a Natural Diamond?
A natural diamond is the hardest naturally occurring substance on Earth, composed entirely of carbon atoms bonded in a crystal structure.
Formed over 1 to 3 billion years ago under intense heat and pressure deep within the Earth's mantle, each diamond is as unique as a fingerprint — a product of time, temperature, and transformation.
Who would have imagined that crushed carbon could become the world’s most celebrated symbol of love?
The Journey: A Diamond in the Rough
Billions of years ago, carbon deep within the Earth’s crust was compressed by unimaginable forces, slowly forming diamonds.
Through ancient volcanic eruptions, these precious gems were carried closer to the surface, where they remained hidden until discovered by early civilizations.
Natural diamonds were first traded in India as early as the 4th century BCE, becoming symbols of power and wealth.
By the 1400s, European nobility had embraced diamonds as fashionable statements — a tradition that continues today.
Are Natural Diamonds Rare?
The rarity of natural diamonds lies not in their existence — but in their quality.
While there are significant stores of lower-quality diamonds, gem-grade natural diamonds are far more elusive.
Today:
-
No major new diamond deposits have been found in over 30 years.
-
Peak annual diamond production occurred in 2005.
-
Many retailers maintain inventories to regulate supply and sustain perceived rarity.
So while there are enough diamonds to meet demand, exceptional quality stones remain rare and valuable.
Sustainability and Responsibility in Diamond Mining
Historically, mining had significant environmental and ethical challenges.
However, the industry has evolved dramatically:
-
99.8% of today's mined diamonds are certified through the Kimberley Process, ensuring they are conflict-free.
-
Large-scale mining companies are committed to improving safety, supporting local communities, and following strict environmental protections.
-
Initiatives now support 1.5 million small-scale miners and families in Africa and South America, providing critical economic opportunities.
-
Environmental progress includes:
-
83% of water used in mining operations is now recycled.
-
Wind energy powers several Canadian mining sites.
-
Modern mining operations use 37% less energy than before.
-
At Tang&Co, we partner exclusively with suppliers who share our commitment to ethical sourcing and environmental stewardship.
Natural Diamonds vs. Lab-Grown Diamonds
| Natural Diamonds | Lab-Grown Diamonds | |
|---|---|---|
| Origin | Formed beneath the Earth over billions of years | Grown in labs in weeks or months |
| Rarity | Naturally rare | Readily available |
| Cost | Typically higher due to scarcity | 30%–60% more affordable |
| Environmental Impact | Mining has improved sustainability, but some impact remains | No mining required, lower environmental footprint |
| Chemical Composition | Pure carbon, identical structure | Pure carbon, identical structure |
| Brilliance | Identical | Identical |
Both natural and lab-grown diamonds are chemically and optically identical — but the story behind a natural diamond offers a piece of Earth's timeless legacy.
Let’s Talk About Value
Because of controlled supply and the inherent rarity of large, flawless stones, natural diamonds command a premium.
While lab-grown diamonds provide a beautiful, cost-effective option, natural diamonds retain a special allure tied to their age, scarcity, and tradition.
For those seeking an heirloom rich with meaning and history, natural diamonds remain the unrivaled choice.
Conclusion: A Billion-Year-Old Symbol of Forever
What’s on your finger?
Nothing less than a piece of Earth's ancient history — carbon crystals forged over billions of years, polished by human hands, and worn as a timeless expression of love.
At Tang&Co, we believe that natural diamonds represent not just beauty, but endurance, strength, and romance — values that have shined through every era of history.
