The description of the mineral matches feldspar, which is commonly pink- to cream-colored with wavy, light-colored lines, and does not effervesce. Garnet is typically not light-colored and often has a more angular shape. Quartz is typically not pink- to cream-colored and does not have wavy light-colored lines. Biotite is dark-colored and does not have the described color or pattern. Muscovite may be light-colored, but it does not have the described patterns and is not commonly pink-colored.
