A modern spelling of Jasper, from Persian via tradition, associated with 'treasurer' and one of the Magi.
Jazper is an inventive respelling of Jasper, a name with ancient and genuinely mysterious origins. The most widely accepted etymology traces it to the Old Persian Yaspar or Caspar, meaning "treasurer" or "keeper of treasure," a name that passed through Greek and Latin into medieval European languages. In Christian tradition, Jasper — along with Balthasar and Melchior — is one of the three names given to the Biblical Magi, the wise men who followed the star to Bethlehem, though these names appear nowhere in the Gospels themselves and were a later tradition.
The association gave Jasper a warm, quasi-sacred resonance throughout the medieval period. Jasper also has a parallel life as a gemstone name: the jasper stone, mentioned in the Book of Revelation as one of the foundations of the New Jerusalem, is an opaque, richly colored variety of chalcedony — red, yellow, brown, and green — used in jewelry and decoration since antiquity. This geological identity gives the name an earthy, tactile quality that has appealed to parents in the contemporary era of nature-influenced naming.
In the nineteenth century, Jasper enjoyed particular favor in the American South and in Britain, where it has always retained a certain country-house gentility. Jazper — with its bold substitution of "J" for the soft opening sound, amplified by the "z" — injects the classic name with jazz-age energy and a streetwise edge. It is a spelling that announces itself, that insists on a second look.
While Jasper has seen a significant resurgence since the 2000s, Jazper distinguishes itself as a more irreverent, expressive choice, beloved by parents who want the name's rich heritage without any stuffiness. The "z" turns a gemstone into a groove.
