“Jewelry is not only about beauty and craftsmanship — it is about responsibility. Every creation must reflect respect for people and the planet, because true luxury cares.”Klaus Stenzhorn

We are dedicated to responsible sourcing, the protection of human rights, and upholding the highest standards of environmental and social responsibility. Our mission goes beyond creating exceptional jewellery — we aim to support communities, protect the planet, and create lasting positive impact.

Ethical material sourcing

At K.S. Jewelry International, we ensure that every partner in our supply chain — from metals to diamonds and gemstones — upholds the highest standards of responsible mining, human rights, and environmental protection.

Our pieces are crafted using gold from trusted mines and pre-consumer recycled sources. For clients seeking the highest level of sustainability, we also offer Single Mine Origin Gold, providing full traceability and assurance of ethical sourcing.

To maintain full control over the origin of our materials, we refine our metals at our own refinery, a sister company of K.S. Jewelry International. This allows us to guarantee both the purity and verified provenance of our recycled metals.


We strictly comply with the Kimberley Process, ensuring that no conflict diamonds enter our supply chain. All our diamonds are natural and thoroughly verified with advanced lab-grown detection technology. Each is accompanied by written guarantees and Kimberley Process Certification from our trusted suppliers

Environmental Approach

Caring for the environment is an integral part of our operations. We are committed to protecting the planet and continuously reducing our ecological footprint. Aware of the resources and energy required in jewellery production, we continually work to improve our processes to minimise our environmental impact.

Our sustainability efforts start with responsible waste management and a strong recycling culture. An advanced filtration system treats production water, removing all residues before it is safely reused or released — with regular testing to ensure full compliance.

To further minimise waste, we offer customers the choice of biodegradable packaging made from sustainable materials. Non-biodegradable zip bags are reused for as long as possible and then responsibly disposed of through our waste-segregation system. We are also investing in energy efficiency by replacing outdated equipment and air-conditioning systems with modern, low-energy alternatives — an essential step toward lowering our carbon footprint.


Product Safety and Material Standards

We take our customers’ safety seriously. We recognise the potential risks of harmful metals such as nickel, lead, and cadmium, which can cause allergic reactions and other health concerns.

That’s why we strictly comply with the European Nickel Directive and European Cadmium-Free Regulations, ensuring that every piece meets the highest safety standards.

To guarantee this level of quality, all metals used in our production are thoroughly tested using advanced Fischerscope X-ray technology. This precise process allows us to verify that our jewellery is completely free from harmful metals — offering our customers confidence, comfort, and peace of mind.

Diversity, Equality and Inclusion

At K.S. Jewelry International, we believe that true excellence begins with diversity. We are dedicated to building a workplace where every individual is valued, respected, and empowered to contribute.

We foster an inclusive culture that celebrates different perspectives and ensures equal opportunities for all — regardless of background, identity, or belief. Our Anti-Harassment Policy guarantees that employment decisions are based solely on ability and performance, maintaining an environment free from bias or discrimination.

We actively support the inclusion of people with disabilities, promote equal opportunities for LGBTQ professionals, and encourage women’s advancement at every level of the company.

Empowering Women

We believe in the transformative power of women to shape the future of our company and the jewellery industry. Gender equality is a cornerstone of our structure — entire departments such as Accounting, Diamond & Color Stone, Gold Stock, Marketing, HR, Production Control and Import & Export are led by women.

We are proud to nurture an inclusive workplace where women thrive not only in creative and managerial positions but also in roles traditionally dominated by men. In areas such as plating and polishing, the majority of our skilled artisans are women — a reflection of our belief that expertise knows no gender.

By ensuring equal pay for equal work, we foster a culture that recognises talent, passion, and dedication — regardless of gender.

Safety & Wellbeing of our Employees

Our people are our greatest strength - we are committed to providing a workplace where safety, health, and respect come first.

Regular fire drills, safety inspections, and risk assessments ensure that every team member knows how to respond in the event of an emergency. Whether working with heat, machinery, or chemicals, our facilities are equipped with clear safety procedures and all necessary protective gear to prevent accidents before they happen.

Health is equally important to us. We support our employees with regular medical check-ups, vaccinations, and vision care.

We uphold strong human rights standards, ensuring fair pay, dignity, and equal opportunity for everyone. Unethical labour practices such as child or forced labour, discrimination, or harassment have no place in our company.
