Chess set - Onyx

Onyx chessboard, Greece, from the late 70s / early 80s, including chess pieces made of iron (gold-plated and silver-plated).
The chessboard measures 39.5 cm in length and width and weighs 7.3 kg.
The chess pieces have a height from about 6 cm (pawn) to 9 cm (king) and together weigh about 3 kg.

The set shows signs of wear. However, it is complete and has no major damage such as dents or breaks. Therefore I would consider the condition quite reasonable.

The visible cracks on the board are not damage, but are due to the natural veining of the onyx stones.
