All diamonds meet the requirements of the Kimberley Process and the resolutions of the United Nations. Naturally we follow “Know your Supplier” best practice and where possible, control the “chain of custody” and track provenance. We are currently working on a blockchain for the future.

Finest diamonds of
the highest quality

Each diamond is between one and four billion years old
and as unique as a fingerprint. But not every diamond is suitable
for our jewellery. We work exclusively with hand-selected
diamonds of the highest grade and quality.
