I slightly prefer [name_f]Opaline[/name_f] [name_f]Azalea[/name_f]
I love [name_f]Opal[/name_f] & [name_f]Opaline[/name_f]! [name_f]Opaline[/name_f] has more options as far as the nn [name_f]Lina[/name_f]. [name_f]Opal[/name_f] is more simple and sleek. Either way they are both beautiful. If I had to choose I like [name_f]Opal[/name_f] [name_f]Anastasia[/name_f] 
Overall I think I prefer [name_f]Opal[/name_f] but [name_f]Opaline[/name_f] [name_f]Azalea[/name_f] is swoon, and you could totally use [name_f]Opal[/name_f] as a nickname
I’m solidly in camp [name_f]Opaline[/name_f]. [name_f]Opal[/name_f] is beautiful, but to me it feels slightly incomplete. [name_f]Opaline[/name_f] gives you nickname [name_f]Opal[/name_f] AND a gorgeous, elegant profile AND a pretty sound. What’s not to love?
