E. Hidden & J. H. Pratt in Amer. Jrnl. Sci. 155 296 The analysis proves that this garnet is not almandine nor wholly pyrope and is distinctive enough in color alone to merit a varietal name. We, therefore, propose the name of Rhodolite, from the two Greek words ῥόδον, a rose, λίθος, a stone. 1931 Amer. Mineralogist 16 563 Excellent samples of rock which contain much gedrite are still to be found on the dump which, however, has been so carefully picked over for rhodolite that good samples are scarce. 1977 V.
