77 Diamonds Sustainability Actions

Offers certified diamonds

77 Diamonds says it sells independently certified diamonds and gemstones. In plain terms, that means the stones are graded or checked by outside experts rather than only by the brand itself. The site also says customers can search diamonds by cut, carat, clarity, and colour, which suggests a focus on traceable product information. This is relevant to sustainability because certification and proof of origin can help buyers understand where a stone came from and how it was assessed.

Promotes conflict-free sourcing

The brand says it offers conflict-free diamonds. That phrase usually means the stones are meant to avoid links to armed conflict or abuse in mining regions. The website also highlights proof of origin for gemstones. These claims point to a sourcing approach that tries to give customers more information about where materials come from, although the material provided does not show independent verification of the full supply chain.

Added lab-grown diamonds

77 Diamonds says it now offers its signature Cupid’s Ideal cut in laboratory-grown diamonds. Lab-grown diamonds are made in a factory instead of being mined from the earth. They can reduce pressure on mining, although the environmental impact still depends on how they are made and powered. The brand presents this as part of its product range, which gives customers a lower-mining option within fine jewellery.

Uses bespoke made-to-order design

The brand offers bespoke jewellery and says customers can work with in-house specialists to create a one-of-a-kind piece. Made-to-order products can sometimes reduce waste compared with holding large amounts of unsold stock, because items are created for a specific customer. The available material does not give enough detail to confirm how much waste is avoided, but the service does show a custom production model rather than a purely mass-produced one.

Provides resizing and returns

77 Diamonds says it offers free resizing within 60 days and returns within 30 days. These services can help extend the life of a piece of jewellery, because customers are less likely to discard an item that does not fit well. This is not a full circular economy (a system that keeps products in use for longer), but it does support longer product use and fewer avoidable replacements.

Held a sustainable gem symposium

A LinkedIn post from Gem Trail Lab says it brought together researchers, industry leaders, entrepreneurs, and students for the 1st International Sustainable Gem Research Symposium in Colombo in 2026. The event focused on traceability, responsible mining, biodiversity, and the future of Sri Lanka’s gemstone sector. The post says the symposium aimed to build stronger links between research, technology, and the people in the gem value chain, which is the chain of steps from mine to market.
