What does the name Rubi mean?
Rubi is a spelling of Ruby, pronounced the same way, so it shares Ruby's meaning and origin.
Ruby is the name of the red gemstone. The word came into English in the Middle Ages from Old French rubi, which goes back to Latin words for 'red' (rubeus, rubinus). DMNES records Ruby as a woman's name in an English marriage record of 1581 and notes that calling it a modern coinage is wrong. It became much more common in the late 1800s, when Victorian parents took up jewel names such as Pearl and Opal. The ruby is the traditional birthstone for July.
