There will be total lunar eclipses on December 21 (2010), June 15 (2011), and December 10 (2011). Solar Eclipses (shadow of the Moon partially or fully blocking the Sun) can occur two to five times a year, but the majority are partial eclipses. Total eclipses occur about once every 18 months, and affect a very limited area. The maximum coverage of the solar disk lasts between 6 and 7.5 minutes.

If her heart is set on a round 1 carat diamond, you can expect to pay between $3,500-$5,500. Conversely, princess diamonds tend to be less costly, as they retain more carat weight during the cutting process. The typical price range for a 1 carat princess cut would be between $3,000-$4,500 (a savings of 15-30%). While the princess cut is relatively new, it is often desired due to the unique cutting and polishing techniques that hide inclusions and show color more clearly.
