Pretty sure it's marble. It is needed for oracle wonder afaik
Stonehenge, Pyramids, The Parthenon, all use stone. Damn, can't think of any decent early wonder, that uses marble right now.
Talking about gems and marble: Only professional warriors to use gem/stone weapons have been the Aztecs, I think. Don't know if we want to pursue their glorious path in history, though.
With all those dots and crosses on the island, are we going to settle, before building some barracks, or will Sparta be a center of troops and swordsmithes right from the start...?
edit:
We have 5 different types of food, we can reach. Red blue yellow and white are each hooking up one (yellow is interchangeable with top right blue(fish). Blue is my favourite one, cause it got cattle for production, clam for food and gold for commerce... -- What else could you possibly need?
Top right blue has 2 food resources, could be a nice place to build the settlers for the other spots, as soon as it got its first border expansion.
edit: Parthenon indeed uses marble not stone.
