What gems were sacred to Cronus?

Cronus, the Greek Titan associated with time and harvest, was often linked to various symbols rather than specific gems. However, in some interpretations, he is associated with the properties of the earth, which could include precious stones like garnets and topaz, reflecting fertility and abundance. Additionally, in more modern interpretations or adaptations, certain gems may be attributed to him, but these are not rooted in classical mythology. Overall, there is no definitive list of sacred gems specifically tied to Cronus in ancient texts.
