I like it. The variant
Sapphira makes it more wearable/usable while maintaining the look of
Sapphire and avoiding the pronunciation struggles that seem inherent in
Saffira. I don't think just anyone could pull it off, though, and would thus be hesitant about using it as a baby name. Maybe it's best as a middle name?
be in this world as if you were a wayfarer, a traveller
