I Sardius Carnelian Jasper II Topaz Chrysolite Sapphire (peridot) III Carbuncle Emerald Chalcedony IV Emerald Ruby Emerald V Sapphire Lapis-lazuli Sardonyx VI Diamond Onyx Sardius VII Ligure Sapphire Chrysolite VIII Agate Agate Beryl IX Amethyst Amethyst Topaz X Beryl Topaz Chrysoprasus XI Onyx Beryl Jacinth XII Jasper Jasper Amethyst While the arrangement differs in Revelation, the stones are nearly identical. For chalcedonius, we should probably read _carchedonius_, a name of the ruby; sardonyx is the onyx of Exodus; the jacinth (sapphire) is probably the “ligure”; the sapphire was the lapis-lazuli, and sardius is equivalent to carnelian. There thus remains only the chrysoprase, which for some reason has substituted the agate. In the eventual association of the foundation stones with the months, the first, the jasper, was assigned to March, with which month the year was reckoned to begin. The list suggested and adopted in Kansas City reads as follows: Month. Birth-stone. Alternate Stone. January Garnet February Amethyst March Bloodstone Aquamarine April Diamond May Emerald June Pearl Moonstone July Ruby August Sardonyx Peridot September Sapphire October Opal Tourmaline November Topaz December Turquoise Lapis-lazuli
