All our silver is 100% recycled 925 sterling silver, sourced from pre-owned jewellery, industrial metals, and electronic components that are refined, purified, and transformed.

70% of the gold used across all of Maria Black’s fine gold collections is sourced recycled, 30% of all gold is sourced fairtrade.

We apply high-quality 18K gold plating to our sterling silver collections with a layer thickness ranging from 1.5 to 2.5 microns.

Rhodium is an rare, silvery-white, hard, stainless, and chemical metal. It is a precious metal and a member of the platinum group. We apply white rhodium plating to our 14K white gold jewellery.

In 2021, we transitioned to lab-grown diamonds in all our 14K fine gold collections. Lab-grown diamonds are real diamonds, possessing the same optical, chemical, thermal, and physical characteristics as mined diamonds.

Cubic Zirconia (CZ), or white zirconia, is a man-made stone that closely resembles diamonds but has a different mineral structure. CZ is used in our sterling silver collections as a diamond alternative, whereas lab-grown diamonds are genuine diamonds.

Nanogems are man-made transparent glass-ceramics that closely mimic the colours, brightness, hardness, and density of naturally mined gemstones. We use nanogems across our sterling silver and 14K fine gold collections.

Pearls are organic materials that grow inside mussels. We use cultured freshwater pearls, farmed and created using freshwater mussels.

Ceramic is an extremely durable and lightweight material, ideal for jewellery due to its scratch-resistant properties. We delicately incorporate it into our 14K jewellery designs.

Resin is a modern alternative to traditional enamel, offering durability without compromising the beauty of our jewellery designs.
