As a word name, Court brings with it a plethora of potential meanings, from a legal gathering, to a stage for basketball or tennis, to a street. Sharp and strong, Court feels right at home with other rugged picks like Rhett and Jett. And yet, Court remains remarkably rare in the US. The alternate spelling Cort is only slightly more popular.

Lucifer is the name of the archangel cast into hell -- theologians disagree on whether he and Satan are separate beings -- and as such has long been on the forbidden list for religious parents. Still banned in New Zealand, Lucifer is occasionally used in the contemporary U.S.: Six boys were given the name in the most recent year counted.

Unlike Pearl and Ruby and more like Jasper, this gem name works well as a boys name. With its strong final X, it feels similar to Alex, Phoenix, Jax, and Rex, while the shiny black quality of the stone feels reminiscent of Orion. Chosen by musician Iggy Azalea for her son in 2020, it has accelerated up the charts and now sits just outside the Top 300.

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

Ruby could be a short form of the Biblical name Reuben and especially its streamlined form, Ruben. As a gemstone name, it's currently enjoying a fresh boom of popularity for girls – nearing the US Top 50 for the first time in almost a century.
