It's main area of interest is trading marble for big production companies. We want a logo that strongly emphasise this primary focus of company. However, it's activities is not limited to only trading marble, but can be extended to production and trading of other common minerals when deemed necessary. Therefore, designed logo should include the primary activity and also reflect the flexibility of working areas.
