<h1>Report Reveals Lab-Grown Diamonds Often Use Coal Energy and Lack True Carbon Neutrality Claims</h1> A global non-profit organization dedicated to natural diamonds released a report addressing misconceptions and greenwashing in the lab-grown diamond industry. The report highlights that over 70% of lab-grown diamonds are produced using coal-reliant energy in certain countries, often involving mined materials and significant water use, sometimes in water-stressed areas. It challenges claims of carbon neutrality, noting reliance on carbon offsets without accounting for full life-cycle emissions, and points out the absence of social sustainability factors like community development. The report also emphasizes the sharp decline in lab-grown diamond prices over the past decade, with significant value loss for certain stones. It stresses the importance of accurate terminology distinguishing natural diamonds from lab-grown ones and calls for transparent, fact-based education to aid consumers and retailers in making informed decisions.
