A Certificate of Fairness

In 2015, due to its excellent service and high customer evaluation, the firm Valmarg Stone LTD was awarded a certificate of fairness.

This high recognition – we are immensely proud of – was issued by the Research Centre of Clients’ Opinions (RCCO) LTD. It is the natural outcome of the many years of hard work, effort and determination we have put into providing the highest level of service and the best quality natural stone for our customers.

Valmarg Stone LTD has proven itself to be a reliable partner to our longstanding distributors and business contacts not only in Bulgaria but also abroad.

This European Certificate of Fairness is an important European document, internationally recognized since 2013.

It validates the company on the market and distinguishes it from competitors. Valmarg Stone has set great standards in front of customers and partners for the level of service, professionalism and quality of the gneissic stone offered.
