This would depend upon a number of factors. Massive, or crystalline? Colorless, or colorful? Clear or opaque? Fractured or flawless? From the Swiss Alps, or from Arkansas? A buck a pound will get you good tumbling grade agate, but a well crystallized rose quartz specimen, or top grade rutilated quartz, or a nice Swiss smoky quartz crystal crowned with pink fluorite crystals... you can add two to four zeroes.
This would be quartz.
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
Olivine would weather faster than quartz
