Standards & Compliance

Commitment to Ethical Sourcing and Quality Materials.

Agata Karwowska is dedicated to creating pieces that reflect exceptional craftsmanship, material integrity, and compliance with UK regulations.

Gemstones

Only natural, conflict-free diamonds are carefully selected for their timeless beauty and appeal. Alternatively, semi-precious gemstones may be incorporated into the design, consistently sourced with ethical standards.

Precious Metals

All jewellery is crafted exclusively from 18k ethically sourced or recycled gold, preferred for its rich hue and longevity. Each piece is designed for longevity, combining timeless style with exceptional quality, using responsibly sourced, high-grade gold.

For bespoke designs, additional precious metals—like platinum or 14k gold—can be selected to complement the piece's unique design and structural needs.

Hallmarking

Each creation leaving Agata’s workshop complies with UK hallmarking regulations and—where required by law—is independently tested and hallmarked by the London Assay Office to guarantee purity and quality under the UK Hallmarking Act 1973.

Commitment to Transparency

Transparency is fundamental to Agata’s approach. Every product description provides detailed information about the materials used, ensuring that each piece is not only beautifully crafted but also ethically produced and certified.
