“A large crystal of calcium carbonate.”
About this item
Calcite is an item that is used with pyrophosphite on a mycelium pool in order to recalcify fossils into enriched bones, which are used on the eastern strange machine in the House on the Hill to gain Prayer experience. It is dropped by monsters found on Fossil Island, and can be mined from boulders inside the Volcanic Mine. It can also be purchased for 70 points each from Petrified Pete's Ore Shop.

Its high alch value of 18 does not cover the 153 nature rune it would burn, so alching is a loss before the item itself is counted.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
