The Honest Guide to Sustainable Diamonds

"Sustainable" is one of the most used words in jewellery, and one of the least explained. We would rather show our working. Here is how to think about a diamond's footprint, and what we can and cannot claim.

1. No mine, no open pit

Traditional diamond mining moves enormous volumes of earth to recover a small amount of diamond, and it can permanently change landscapes and waterways. A lab grown diamond needs no mine at all. This is the clearest, most certain benefit of choosing lab grown.

2. Energy is the big question

Lab grown diamonds need electricity to grow. If that power comes from coal, the footprint can be significant. If it comes from renewables, it falls sharply. That is why we asked where our diamonds are grown. The CVD facility in Surat that grows our diamonds is reported to run on solar power, generated at a solar plant in Navsari, Gujarat.

3. Traceability

Because our diamonds are grown, cut and set under one roof, each stone can be traced from growing chamber to finished piece. There is no uncertainty about which country, mine or middleman it passed through.

4. Giving back

The family behind our diamonds reports that it has planted more than 100,000 trees across Gujarat, and its charitable trust has contributed more than 10% of net profits to community causes since 2019.

5. Made to last

The most sustainable jewellery is jewellery you keep. Solid 14K gold does not peel or wear through like plating, and a well-set diamond lasts a lifetime. Buy fewer, better pieces, and wear them often.

What we will not claim

We will not tell you a diamond has "zero impact". Every manufactured product uses resources. We will not quote figures we cannot stand behind. The facts above are reported by our diamond house, and we will keep updating this page as more independent data becomes available.

Questions to ask any jeweller

• Where was this diamond grown, and what powers the facility?
• Who graded it, and can I see the report?
• Is the gold solid, plated or vermeil, and what karat?
• What happens if I need a repair or a resize?
