I have been working with diamonds from different sources in the past and have been sceptical at first, when I heard about lab-grown diamonds. I used to work with diamonds that have been certified through the Kimberley process and also with diamonds with certificate of origin from Canada. In my opinion the Kimberley process is a good thing, but not efficient enough. You can read more about that here.

In my opinion lab-grown diamonds are currently the diamonds with the least negative impact on humans and nature. Lab-grown diamonds do need a lot of energy for their growth, but at least we do have a choice here to work with renewable energies. Right now some of the lab-grown diamonds I use have been using renewable energies, but not all. But I hope I can soon offer it for all of them.

Bigger diamonds I am sourcing from Canada too. The CANADAMARC diamonds are sustainably and responsibly mined. The source of each stones can be followed with a serial number on the stone. More here.

So far there aren't a lot of reliable offers for used and recut diamonds, but they do exist and I am happy to use them. If you yourself still have some diamonds from some old jewelry or other, we can have a look at them and maybe use these as well.

are mined fair and environmentally friendly through small scale ming. Colorful and high in quality, with a transparent supply chain. Besides lavender or lemon colored sappires or pink rubies there are different stones, colors, sizes and shapes available. At the moment I am sourcing these stones for example through Miadana or Ceylons.

Stones can, if not used in your old jewelry anymore be recut and used again. If you have some stones yourself, we can have a look at them. Also I source them through suppliers of recut stones like the stone company Schuett.
