The gem is certainly gorgeous - I have a string of very low-quality opals, bought over a century ago by an impoverished ancestor who didn't emigrate to
Oz after all - and my mother drove an Opel for a while, happily enough, but I don't like the sound or the look of the name. And I can't decide if it's better or worse, as a name, than
Mercedes,
Lexus,
Cressida ...
