Materials & provenance
An engagement ring is made to be treasured for a lifetime and beyond, so we believe it's important to consider not only its beauty and quality, but also the impact of the materials used to create it.
​
With respect for people and the planet at the heart of our approach, we carefully select our gemstones and use recycled precious metals wherever possible. Our aim is to create beautiful, enduring jewellery while making thoughtful choices about how it's made.​
australian
sapphires
All our sapphires are sourced from the Central Queensland Sapphire Fields in Australia, a region renowned for its beautiful and distinctive gemstones.
​
Australia has established environmental regulations, workplace health and safety requirements, and labour protections that help support more responsible mining practices.
​
By sourcing our sapphires from this region and working with trusted suppliers, we aim to offer beautiful, high-quality gemstones with greater transparency about their origins.
Canadian
Diamonds
All our made-to-order rings and new ready-to-ship rings feature traceable CanadaMark™ diamonds, sourced from Canada's Northwest Territories.
​
CanadaMark™ diamonds are tracked through the supply chain, providing assurance of their Canadian origin. They are mined under Canadian environmental and labour regulations, with consideration for the natural environment and local communities.
recycled
Precious metals
We use recycled precious metals in our rings, choosing to make use of existing resources rather than contribute to the demand for newly mined materials.
​
Gold and platinum can be recycled and refined without compromising their purity or quality, making them ideal for creating jewellery that is designed to last a lifetime. Recycled precious metals have the same beauty, durability and value as their newly mined equivalents.
​
All rings are hallmarked at Birmingham Assay Office.
made in the uk
Every ring is designed by Kiya and made in the UK, combining modern jewellery-making techniques with traditional craftsmanship.
​
Each piece is carefully crafted, set and finished with attention to detail, creating jewellery of lasting quality, designed to be treasured for generations.
