Your questions, answered.

Carbon neutral lab grown diamonds are high-quality diamonds created in a laboratory setting, which have had their carbon footprints offset through verified carbon reduction projects. This makes them an environmentally-friendly and ethical alternative to mined diamonds.

We've partnered with Clear Neutral, a leading carbon neutral certification company, to meticulously evaluate and offset the carbon emissions generated during the production of our diamonds. This includes sourcing raw materials, diamond cultivation, and final polishing. Clients will receive a verifiable certificate as proof.

Clear Neutral is a leading carbon neutral certification company based in Australia. They don't grow diamonds. They offset the carbon footprint of lab grown diamonds by investing in certified projects that reduce or remove carbon dioxide from the atmosphere. These certified projects include methane gas capture in a landfill, creation of wind farms, forest conservation, clean cookstoves, solar energy, and hydropower, among others. Certified projects must contribute to at least three United Nations' Sustainable Development Goals.

The United Nations' Sustainable Development Goals (SDGs) are a set of 17 global goals established in 2015 to address various social, economic, and environmental challenges. While not exclusively focused on carbon neutrality, they promote sustainable development practices that contribute to reducing greenhouse gas emissions. Key goals related to carbon neutrality include:
Goal 7: Affordable and Clean Energy - Increase access to renewable energy sources.
Goal 11: Sustainable Cities and Communities - Develop eco-friendly urban infrastructure.
Goal 12: Responsible Consumption and Production - Promote resource efficiency and waste reduction.
Goal 13: Climate Action - Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters.
Goal 15: Life on Land - Protect ecosystems, halt deforestation, and restore degraded land.

Our carbon neutral lab grown diamonds do not cost more, as we happily cover the price difference to encourage sustainable choices. Our carbon neutral lab grown diamonds remain competitively priced, making them an affordable and accessible option.

Through our partnership with Clear Neutral, we support various verified carbon reduction projects worldwide, such as renewable energy initiatives, reforestation efforts, and sustainable community development programs.

No, only our lab grown diamonds for now. However, our commitment to sustainability is a core value of our brand. While our carbon neutral lab grown diamonds are at the forefront of this commitment, we strive to incorporate sustainable practices across our entire collection.

We have a variety of suppliers all around the world. Our stones come from labs in Europe, Asia, and America, from countries like the US, Canada, Belgium, India, and Germany. Regardless of the location of the lab, all of our lab grown diamonds are independently graded and certified by either the GIA or IGI and are Carbon Neutral Certified by Clear Neutral.

Yes, lab grown diamonds have the same chemical, physical, and optical properties as mined diamonds. The only difference is their origin. While diamond mining has devastating effects on our environment and communities, lab grown diamonds are created in a controlled environment, ensuring their ethical and sustainable nature.
