Huge Slab Of Agate Bookend - Carnelian Colored Geode

Huge Slab Of Agate Bookend Carnelian Colored Geode Quarter cut large piece Polished Beautiful raw side and anti- slip on the bottom. Anti slip is coming off. Part of an label under but not enough to read. Please note: I do not know enough about stones to determine if this is colored agate or natural carnelian. I listed as colored but it may be natural. Please look at all photos as I cannot represent it one way or another as I don’t have the experience. Thank you
