Shell, Shell and Sand - Imperial
Imperial's Shell and Shell and Sand patterns are exactly the same except that the Shell and Sand has stippling between the shells as shown on the right. When Imperial first released the Shell version it might not have sold well, so they added the stippling to make the design more interesting. It's worth noting that some auctioneers may list either pattern as Shell, so check carefully.

Both patterns are found in 7 to 8 inch bowls and 9 inch plates. Colors found inlcude amethyst, blue, green, helios, marigold, teal and smoke,
