Didima marble originating from Argolis, is the most mined marble in the region, with a well-established position in the domestic marble market. It is a dolomitic marble of beige color with light colored stripes. It has excellent durability and is ideal for both indoor and outdoor use, floors, and stairs, due to its mineral composition. It also has high heat capacity which makes it ideal for underfloor heating.
