Altair, Amyas, Amor, Agate, Adele, Annis.
By the way, none of these names is unique. If something is recognisable as a name, then it's been used before - which means it's not unique.
'Writing desk' or 'smorgasbord' would, I hope, be unique but I don't recommend them.
Your request for 'unusual yet unique' names doesn't make sense.
