3-Pc. Lot Red Abalone Haliotis Rufescens Shell Post 1940's Pt. Arena California. Not raised commercially from abalone farms like they have now. The sizes in this lot are: 8-3/4" L x 5-5/8" W (completly polished outside/inside) the only one. Second size: 7-1/2" L x 6" W, third size: 7-3/4" L x 6" W. Red abalone has been used since prehistoric times the Native American people harvested the species along the central northern coast of California. Being one of the largest "edible" species in the family Haliotidae they were a great food source. Even though red abalone has been used since the early times, these red abalone were harvested in the 1940's (1942 Point Arena, California) for their abundant food source. These shells were then used in jewelry making, then passed down in the family for years, mostly forgoten about just packed away and stored. Great for crafts, inlays, jewelry making and many other uses, rich vibrant colors and hues, vibrant iridescence colors, beautiful mother of pearl. Excellent shape for any collector or hobbyist.
