Starough
About

A diamond trader, not a middle-man

Our story

Starough was founded in Antwerp in March 1980 as a rough diamond trading company.

From rough, we moved into manufacturing, and then into selling small polished sizes under one carat: mostly non-certified rounds, in parcels, for manufacturers and dealers. These stones are the foundation of the jewellery industry. Knowing them inside out set the standard for everything we do.

When the next generation joined, we added GIA-certified stones in all shapes, rounds and fancies. Today our stock runs from small sizes up to around five carats, with select stones close to ten carats.

We have grown through the trust of our clients, and we bring the same care to every stone we sell.

Polished diamonds in many shapes

Starough today

Starough is a third-generation family business, built to last. Investing in sustainability is part of how we grow.

We use a modern ERP system to track every stone and parcel as it moves through our business. It supports ethical sourcing and the ESG standards we work to. Since 1980 we have aimed to leave a positive mark on the people and places we work with.

Leading luxury brands around the world rely on us as a one-stop diamond supplier. We work openly and carefully at every step, from rough to polished.

Our mission

To be the first choice for all diamond consumers looking for ethically sourced, high-quality stones. We keep buying diamonds open and sustainable, we build long-term relationships, and we work to earn our customers' trust with every order.
