Responsibly Sourced

What do your gems say? They belong to you, but the future belongs to all of us.


From the southern tip of Africa to the vast depths of Asia, we spare no distance to find the raw stones that will be your personal statement.

For us at Greene & Co., the value of a gem is not only measured by its quality and brilliance, but by the dignity and prosperity it creates for those who have so carefully extracted it from the Earth.


We partner only with those who employ the most environmentally sustainable methods and technologies. Eco-friendly methods of mining gems are not always the simplest or easiest, but they are the right thing to do. We do not support any mining process that damages the Earth’s precious, natural resources.
