Urban Forestry Initiative

In line with our commitment to sustainability and environmental responsibility, we've launched an Urban Forestry Initiative under the leadership of our group company ‘J.K. Star’ in the major cities of Gujarat, India—the very region where our diamonds are grown and polished.

As part of this initiative, we've already planted over 100,000 trees, aiming to green urban areas where there's a pressing need for increased foliage. This initiative goes beyond mere corporate social responsibility; it's a heartfelt pledge to contribute positively to the communities in which we operate.

Through our Urban Forestry Initiative, we're not only beautifying our cities but also promoting cleaner air, reducing pollution, and enhancing the overall quality of life for residents. We're proud to be part of this endeavor, and we remain committed to continuing our efforts to create greener, more sustainable urban environments.
