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

When you purchase a C-® Carbon Negative Diamond, you can be sure you are helping to protect life on Earth from the effects of Global Warming and human-caused Climate Change.
