Onyx is considered a semi-precious stone. Since the ancient times it has been used in decorative art. Onyx is utilized in finishing of leaded panels, fireplaces, countertops. It is often used in interior design and statues production. Onyx stones have different colors – green, yellow, red. It is not easy to describe the color spectrum of onyx because every batch of stones has a unique pattern structure and color. Onyx lets the light through and can be used as an independent part of the interior (in fireplaces, partitions etc).
