Some would say that's too much
But it depends on how far your relationship has progressed and how financially capable you are.
If that's how much you want to spend, I think it's ok, especially since it seems you are beyond the casual(non-committal) dating stage.
I once bought diamond earrings as a gift but ended up exchanging them for a necklace+pendant instead.(she can wear it all the time)
You can get a good deal at the gift center.
OR go with the purse(brand/style you know she likes), and if you have remaining dough buy tickets to a show like Cirque De Soleil or that Dinner Theater thing they have down at the embarcadero
