At the heart of our jewellery lies a commitment to authenticity and sustainability. We use 100% natural, artisanal, ethically sourced gemstone rough, which is meticulously cut right here in Scotland.

In recent years, lab-grown gemstones have gained popularity, often marketed as a more sustainable, ethical, and cost-effective alternative to natural stones. However, when examined more closely, the "green" image surrounding lab-created gems begins to show its flaws.

Despite not being mined from the earth in the traditional sense, lab-grown gemstones still rely on raw materials that must be mined and transported to manufacturing facilities. These facilities, largely located in Asia, often depend on coal-powered energy, contributing significantly to pollution and greenhouse gas emissions. Furthermore, the production process generates industrial waste that frequently finds its way back into the environment.

With this in mind, I spent a long time considering how—or even whether—I could incorporate lab-grown materials into my work in a way that aligned with my values.

That’s when I came across a truly unique opportunity: I discovered the last known stock of lab-grown sapphire produced by Salford Electrical Instruments in Lancashire, England. This material was manufactured on June 6, 1951, for use in the electronics industry, and is of the highest quality.

What makes this even more special is the provenance—I know exactly where and when it was made. Rather than support modern, industrial-scale lab gem production, I’ve chosen to upcycle this historic material. I believe in giving new life to materials with a story, and I take great pride in cutting gemstones that carry a traceable legacy.

I am proud to offer this rare, vintage lab-grown sapphire—crafted in the UK over 70 years ago—as a beautiful, ethical, and truly meaningful alternative. Each gem is not only a piece of history but a step towards thoughtful, responsible jewellery-making.
