Cullen Initiatives

Undoing the damage of the mined diamond industry

Our Goals as a Company

01. People

We take a comprehensive approach to help people break out of the poverty cycle, with the aim of supporting as many individuals and families as possible. We do this through various initiatives, such as by providing them with employment opportunities, access to nutritious food, and quality healthcare. By working together, we can make a real difference in the lives of those who need it most.

02. Environment

The mined diamond industry has had an enormous negative impact on the environment. We have undertaken complex restoration projects to reverse this damage, including a massive tree-planting project. In this, we are working with local communities and philanthropic organisations to replant trees in damaged locations, restore the landscape, and create a sustainable habitat for both the people and the native wildlife.

03. Climate

We all need to do our part to reduce our collective carbon footprint. Accordingly, we only offer lab grown gemstones with the aim that they will be 100% carbon neutral by 2023. We will also be moving towards running on renewable energy sources, which will help us further protect our planet for future generations. We are proud to lead the way in sustainability and hope others will follow.

Building a Better Future for People

As a family business, Cullen Jewellery is passionate about giving back and supporting those harmed by exploitative industry practices. The Jewellery industry is known for its damaging impact on African countries and communities due to diamond mining — 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.

Our Initiatives

01. 10 Trees Planted for Every Ring Sold

Working with the Eden Reforestation Project, we plant 10 Trees for every ring sold. By planting these trees, we are working towards regenerating the landscape while simultaneously creating employment for the local communities.

02. Recycled Materials

To reduce our use of finite resources, we exclusively use recycled precious metals in all our jewellery. We source our metals from certified recyclers who follow responsible practices, and we use minimal processing to protect the environment.

03. Pledge Against Mining and Mass Production

Cullen Jewellery has a pledge against mining and mass production. The former happens at the expense of local ecosystems and communities, while the latter involves fast fashion principles that are currently overrunning the fine jewellery industry. Accordingly, we only use lab grown gemstones and specialise in made-to-order products.

Building a Better Future for the Climate

Cullen Jewellery is committed to protecting the climate. As a result, we only offer lab grown diamonds and moissanite as these gemstones do not come with the high environmental and social costs of mined diamonds.

Cullen Jewellery recognises that energy is required to grow them. While these stones need far less total energy to produce than mined diamonds and are violence-free, we are going further by only using lab grown gemstones that are 100% carbon neutral by 2023. Therefore, when choosing from Cullen Jewellery’s lab grown product range, you can rest assured that you are making a responsible choice for the planet.

Our Goal

100% Carbon Neutral Lab Grown Gemstones by 2023

By working with a third-party auditor, we aim to offer 100% carbon neutral lab grown gemstones exclusively by 2023. This process involves reducing our carbon footprint and offsetting any emissions produced in the growing process. We are committed to being a sustainable company and are proud to take this vital step in the fight against climate change.

Supporting Local Causes

As a Melbourne-founded business, we feel it is our responsibility to give back to the community that has supported us throughout the years. That is why we regularly donate to and sponsor local organisations and charities. These include:

Cancer Council The Otis Foundation Kew Football Club Australian Red Cross Peter Mac

Awesome! Please send an email to; we’d love to chat.

Diamond mining has many detrimental impacts on communities and the environment. This ranges from deforestation to infrastructure destruction. The mined diamond supply chain also results in conflict and blood diamonds. Beyond that, human rights abuses, violence, and corruption are synonymous with the exploitative mining process.
