Par for the course on premiums is 1-2% of your declared value per year and the homeowners companies are usually actually pretty price competitive. It does pay to shop, especially if you live in a high risk area like NYC or LA. Premiums vary with the type of coverage you get and, of course, the limits you set. You can get lower premiums by increasing deductables, reducing the upper limit (meaning the appraised 'value') and occasionally things like alarm systems on your home, getting a gemprint on the diamond and the like.
