At Culet Jewellery, the story behind your piece matters just as much as the piece itself. Every diamond, gemstone and precious material we use is sourced with care, transparency and respect for both people and planet.
Our commitment is simple: luxury shouldn’t cost humanity, or the Earth.
We work exclusively with **natural diamonds sourced from reputable suppliers who comply with the Kimberley Process Certification Scheme — a global agreement designed to eliminate the trade of conflict diamonds.
Every natural diamond we select for you is independently certified (GIA/IGI)
Each stone is documented, traceable and verified as conflict-free
Our suppliers operate under strict labour, ethical and trade regulations
No shortcuts, no grey areas, no unverified sourcing — ever.
The Kimberley Process was established in 2003 and is recognised by the United Nations. It ensures rough diamonds are tracked and certified from the mine to the cutter, preventing the trade of stones that fund violence or unethical practices.
Put simply:
If it hasn’t passed through the Kimberley Process, we don’t touch it.
Alongside natural diamonds, we also offer lab-grown diamonds of exceptional clarity, beauty and brilliance.
Lab diamonds are identical in structure and sparkle to natural diamonds, but are grown in highly controlled clean-energy facilities rather than extracted from the earth.
Lower environmental footprint
No large-scale mining disruption
Often better value for carat and clarity
Guaranteed conflict-free origin
They offer the same luxury — with a lighter environmental impact.
Our sapphires and other gemstones are sourced from responsible mining partners and specialist gemstone cutters who follow strict labour, safety and environmental standards.
We work only with long-established, reputable gemstone houses who:
Ensure safe working conditions
Support community livelihoods
Minimise environmental disturbance
Provide traceability from rough stone to polished gem
Each gemstone is chosen by eye and by hand — for colour, fire, durability and ethical transparency.
Jewellery is personal — and we believe the journey of each piece should reflect care, respect and integrity.
From your first consultation

→ to final polishing in our workshop,
every step matters.
Your jewellery tells your story.
We make sure its origins tell the right one.
