It does not refer to the agate that has been passed down during the Warring States Period, but the agate found in the Hebei and Liaobei regions by archaeology, which is very similar to the agate jewelry in the Warring States Period, so this type of agate is named "Warring States Red Agate". Warring States Red Agate is one of the most popular products in the current agate market. The main reason is that the output is extremely low, the resource reserves are very small, and the storage value and artistic value are extremely high.
