The leftmost ore is compressed emerald.

All new gear (excluding sapphire and ametrine sets) can be crafted on a crafting table like diamond gear. Ametrine and sapphire sets are upgraded from iridium armour using the corresponding upgrade templates (found in the time capsule) and the correct material.
