Sustainably sourced gemstones

Sustainability

A progressive journey

Sustainability as a progressive journey, not a fixed state

For the avoidance of doubt, whilst pursuing every means possible of reaching a truly sustainable state, we would be the first to admit that there is always more to be done.

We aren't here to say we are perfect, we simply want to explain our approach, the positive practices we adopt and highlight our continual pursuit of perfection...

A sense of adventure

Expeditions in search for the finest gems

We are determined to get to a position where each gemstone used in our jewellery should be traceable back to the source. Where possible we want to know where the stone was found, who found it, where it was cut and who cut it.

This all starts with our expeditions...

With various expeditions to far flung corners of the earth in search of precious gems, we want to immerse you in our world. We are building long term personal relationships to create a sustainable future for the industry we love.

B-Corp

Widely regarded as one of the most prestigious certifications across all industries, B-Corp exists to bring to address societies biggest challenges.

B-Corp Certification is a designation that a business is meeting high standards of verified performance, accountability, and transparency on factors from employee benefits and charitable giving, to supply chain practices and input materials. 

We are delighted to become B Corp Certified in 2024 - making us the first top tier UK based jeweller to do so.

Expedition sourcing

We are striving to ensure all our gemstones are sourced as part of our expeditions, giving us total transparency (and peace of mind) on each piece's origin.

Made to order

We only make pieces our clients desire, meaning that no pieces or materials are used unnecessarily, for creations nobody desires.

Whilst many of our supplliers are Responsible Jewellery Council Certified, as part of our B-Corp certification we have requested all our suppliers sign a code of conduct to adhere to our own high standards.
