The founders' vision

Combining the finest craftsmanship with the benefits of e-commerce

By founding the first luxury online jeweller in Europe, Maximilian Hemmerle and Georg Schmidt-Sailer are realising their vision of combining supreme craftsmanship with e-commerce: personal advice and assistance, high-quality service and superb quality are offered in a contemporary shopping experience in which individuality reaches perfection.

The founders speak on behalf of the whole team - from the customer service department to the goldsmith's workshop and gemstone buying department:

"Our customers measure us against the benchmark of the top international addresses for quality jewellery, while also expecting the individuality and quantifiable benefits that only the Internet can bring. It is our great pleasure to fulfil these standards of perfection day by day."
