Pearls are formed within the soft tissue of mollusks, and start as a grain of sand. The mollusk concretes thin layers of calcium carbonate over the grain of sand. Therefore, a pearl would be considered sedimentary.
That is correct. A detrital (or "clastic") sedimentary rock is formed by sediment grains that have been weathered and eroded by existing rocks and then deposited as layers.
