Exquisite Coloured Gemstones from East Africa

Exquisite coloured gemstones · Tsavorite & Ruby

A gemstone is light turned to stone – millions of years of Earth's history captured in a few carats. From the vivid green of a tsavorite to the deep fire of a ruby, we trade in coloured gemstones of rare purity: sourced directly at the origin and selected for discerning clients in Germany and Bangkok.

Gemstone varieties: Tsavorite, Ruby, Tourmaline, Sapphire, Spinel

From tsavorite and ruby to tourmaline, sapphire and spinel – our world of exquisite coloured gemstones

Origin & Quality

Directly from the Mine to the Client

Our focus is on tsavorite – the vivid green garnet found exclusively in East Africa – and on fine rubies. Through our direct access to mines in Voi (Kenya) and Tanzania, we know the origin of every stone and can guarantee quality and fairness along the entire chain.

Our stones are sold to jewellers, goldsmiths and collectors in Germany and at the international coloured-stone trading hub of Bangkok – where true connoisseurship is at home.

Origin with Responsibility

Responsible Mining

A gemstone is only truly beautiful if its journey is beautiful too.

For PM International, quality does not begin at the cutting table but at the mine – with the people who bring the tsavorite out of the rock, and with the nature it comes from. We source our rough stones exclusively through partners committed to the same high standards as we are.

Every stone passes through a controlled and fully traceable process – from the audited mine through documented purchase to the finished cut gemstone. This allows us to verify origin, working conditions and legality for every tsavorite. Stones from conflict-affected or illegal mining are strictly and without exception excluded.

Safety & Occupational Protection

The safety of the miners is our highest priority. We only work with mines that guarantee recognised safety standards, protective equipment and regulated working hours.

Human Rights & Fair Labour

No child labour, no forced labour, fair and timely pay. We respect the dignity and rights of every person along the entire supply chain.

Law & Compliance

We comply with all national and international laws – from the mining and export regulations of the countries of origin to the due-diligence obligations of the German Supply Chain Act.

Traceability

Every rough stone is documented. Origin, purchase and transport route are traceable – transparent towards clients, authorities and partners.

Environment & Restoration

We rely on low-impact, small-scale mining, minimise interference with soil and water and support the restoration of used land.

Community & Local Value Creation

Mining should benefit the people on site. We promote fair prices, local employment and investment in the communities around the mines.

Transparency

From Rock to Radiance

Trust is built on traceability. On request, we disclose the available origin and inspection certificates for every stone and welcome independent audits along our supply chain.

Responsible trade is not an optional extra for us – it is the foundation of our business. Anyone acquiring a tsavorite from PM International receives not just a beautiful stone, but the certainty that its journey was fair, safe and lawful.
