Comparing Carbon Footprints: Synthetic Vs Natural Diamonds'

Article Contents

The analysis of carbon footprints for synthetic versus natural diamonds highlights significant differences in environmental impacts. Synthetic diamonds, manufactured through high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD) techniques, typically emit about 511 kilograms of CO2 per polished carat and consume around 250 million joules of energy per carat.

This energy-intensive process is necessary to simulate the natural conditions deep within the Earth where diamonds form. In contrast, natural diamonds, which develop naturally in the Earth's mantle, require less energy, using approximately 160 million joules per carat. However, extracting natural diamonds disrupts both terrestrial…
