Possibly one of the most beautiful thundereggs in the world with their elegant shapes and warm colours - not to be confused with the famous Laguna Agate. They have a distinct brick-red matrix that tends to take a very matte polish. The agate tends to be simple and tending towards red. Atoll structures are common.
