The mine is due to close soon pushing the value of these diamonds up further. Famous for its pink diamonds and lovely champagne coloured stones, a favourite of Black Finch designs. These beautiful stones are rare and grow rarer everyday….Īustralia's biggest diamond mine and the worlds largest diamond deposit is the Argyle mine in the Kimberly region of Australia.

The majority of coloured diamonds originate in Australia, from Australian material, mined with Australian ethical standards. It is the source of some of the fabulous coloured jewels in our collection which are unique to the regionĪll diamonds supplied by Black Finch are conflict-free. This mine has been in the same family for generations. We also stock some beautiful Ceylon sapphires that we've sourced from a small family-run mine based in Sri Lanka (home of the Ceylon sapphire).

At Black Finch, we love coloured jewels rare colour-change stones, bi-colour stones and unusual cuts and we can't wait to share them with you.

The selection of sapphires offers a magical array of colours from brilliant green, deep blue, orange and lilac as well as the famous Australian parti-sapphire. This means that mining practices are dictated by seasonal and cyclical climate changes. Rainfall is required to work a sapphire mine. Sapphire mines are very shallow, having a far lower impact on the land, than large open-cut or incredibly deep mines. Australia is home to independent, small, family-run operations, often with just a single person working the leasehold on the minefield. This allows us to have unprecedented supply-chain transparency. We have visited the mine sites to verify the working conditions and witness the minimal impact extraction has on the environment. We specialise in ethically and sustainably sourced Australian sapphires.
