sovira = sapphire (noun) (gemstone) (some things Google found for "sovira": an uncommon to rare term; a last name; a first name; Sovira (or Souveera) was an ancient tribe and territory in Northern India which is in present day Sindh province of Pakistan)
Word derivation for "sapphire" :
Basque = zafiro, Finnish = safiiri
Miresua = sovira
Both the Basque word and the Finnish word contain a "f". It's likely that "sapphire" was a borrowed word in both languages. I modified the "f" to a "v" for Miresua.
This Miresua conlang word has been changed. The word for "sapphire" is now "sovari".
