Sardonyx

Wear a sardonyx or for thee,
No conjugal felicity;
The August-born without this stone,
`Tis said, must live unloved and lone.

— Gregorian birthstone poem

Sardonyx is an alternate modern birthstone for August in Britain, and was likewise the modern August birthstone in the U.S. beside peridot until 1912, when the banded gemstone was stricken off the list as August gemstone. Sardonyx is in fact the traditional birthstone of August, and was the ancient August stone in the old Polish and Arabic calendar. Before the gemstone appeared in these ancient calendars as gemstone for August, sardonyx was a zodiac stone for Leo, which falls partly in the month of August.

Sardonyx is the variety of onyx where the black bands are replaced by red, which is composed of sard or dark carnelian, hence the name sard-onyx.

The other most widely accepted traditional stone for August, carnelian, which hails from old Roman, Italian and Hebrew calendar, is also red. It is apparent that red is the traditional August stone color. This is seconded by the Russian August gemstone, alexandrite, which is half the time red, as well as by ruby, the August birthstone in the Hindu calendar.

Of course, other colors are also seen among the birthstones for August. Sardonyx, moonstone and diamond are white; topaz is yellow; while sapphire occurs in all other colors beside red.
