While not affiliated with the numerous harms of mining, Cullen Jewellery recognises that energy is required to create lab-grown gemstones. Our devotion to leading on environmental responsibility means we are offsetting our emissions through diverse initiatives to build a better planet for all.

Our Initiatives Include:

  • All stones to be carbon neutral by 2023
  • 10 trees planted for every order
  • No mined diamonds or other mined gemstones
  • Recycled Gold and other precious metals
  • Pledge against mass-production

Philanthropic Initiatives

As a family business, Cullen Jewellery is passionate about giving back and supporting those harmed by old-fashioned industry practices. The Jewellery industry is known for its negative impact on African countries and communities due to diamond mining exploitation — and we are determined to do things differently.

In addition to not using mined diamonds and other mined gemstones, we aim to help rebuild these communities and create a better future for those who live within them. We do this by supporting humanitarian organisations and providing marginalised communities with funds, nutrition, shelter, healthcare, education, and employment to help break the poverty cycle.
