Diamond Studs – Deal or No Deal?

I really don’t know much about diamonds, as I usually wear white opals or dark blue sapphires. I just purchased my first pair of diamond studs from Overstock.com and I want to know if they are a good deal.
They are “14k White Gold 3/4ct TDW Round Diamond Stud Earrings (G-H, SI1-I1)” and I got them for $564.20 USD. Is that a good price?

That is a good price and about right for a 3/4ct diamond studs because a 1ct. is a $1000 or more.
