It sounds like it could be a fairly good name until one discovers that it's not a name at all but a Hebrew word meaning 'scab', 'burning', and 'inflammation'. After knowing the meaning, it's not something that I would use. It sounds nice, but the meaning ruins it.
Also, Tsaphira doesn't mean 'crown', it means 'sapphire'. It could make for a decent name.
