Khelrtva
A khelrtva is a calligraphic monogram, seal or signature of the Georgian monarchs, patriarchs, royal and noble princes.
Word "Khelrtva" literally means "to decorate, adorn or beautify with hand" in Georgian language, "kheli" meaning a hand and "rtva" meaning to decorate or adorn.
Khelrtva signatures were written in one of the three Georgian scripts, mostly in Nuskhuri and Mkhedruli scripts, though the monograms especially the royal ones were written in Asomtavruli script. Every Georgian monarch had its own individual khelrtva.
