Welcome to the Carbon Negative Diamond Company, where we do one thing:

Sell millions and billions of Diamonds made of carbon sequestered from greenhouse gases to reverse the effects of human-caused climate change.

Diamonds bearing the USPTO-registered C—(C Minus®) Carbon Negative trademark are grown using renewable energy, like solar power. Every C-® Diamond grown sequesters more carbon in the diamond than is released into the atmosphere during its growth, reducing carbon emissions that cause Global Warming and Climate Change.

Carbon sequestration is the capture and secure storage of carbon that would otherwise be emitted to, or remain in, the atmosphere. (source)

Every C-® Diamond converts gaseous carbon into a solid diamond, reducing the amount of atmospheric carbon by the weight of the diamond. When you purchase a C-® Carbon Negative Diamond you help protect life on Earth from the effects of climate change.
