The Cullen Difference
We celebrate life's cherished moments, conscientiously. We craft premium engagement rings and fine jewellery exclusively with carbon neutral lab grown diamonds and moissanite. Situated in the heart of Melbourne, Australia, our legacy of superior craftsmanship lies in the hands of jewellers with generational experience. By pairing accessible elegance with a commitment to sustainability, every piece is more than a symbol — it's a promise of love, ethically made and faithfully kept.
Our experienced jewellers use only the finest materials to craft each ring with precision and care. At Cullen Jewellery, you can rest assured knowing your engagement ring is brought to life by expert hands to last a lifetime and beyond.
Our Key Differences:
- Lifetime warranty
- Branded and certified gemstones
- We invest significantly in R&D
- Impeccable attention to detail
- We don’t profit from repairs
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

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.
