Meaning & origin

Rubi is a modern respelling of Ruby, the traditional gemstone name that has been in use since the 19th century. It first appeared in U.S. records in 1957 and saw a surge in popularity that peaked in 2005, when it reached rank 1076. The name has since been on a downward trend, but it remains a vibrant choice among families in Oklahoma, Oregon, and Arizona. Its simplicity and clear association with the red gem give it a straightforward appeal, while its spelling sets it apart from the more conventional Ruby.

Rubi is a variant spelling of Ruby, which comes from the Latin 'ruber' meaning red. The ruby gemstone has long been prized for its deep red color, and the name gained popularity in the English-speaking world during the 19th century as part of the trend of using gemstone names for girls. The spelling Rubi emerged as a simplified or creative alternative, particularly in the late 20th century.
