“Paint agates” is anterm used to describe opaque vs. translucent agates.

Most agates from as translucent Chalcedony.

For an unknown geological reason others form as opaque. This is an interesting example.

I need to research agate formation more. I've actually been thinking about doing my undergraduate thesis on agates or maybe opals.

You should! Agate formation is very understudied and misunderstood.
