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.
1 Quarter carat or less diamond, $125 to $500 set in 14 carat gold. 2  0.3 to half carat diamond, $750 to $1,000 set in 18 carat gold or platinum, possibly more if ASG/GIA certified.  For diamonds up to 0.75 carat, or smaller ASG/GIA certified stones, $1,000-$2,000.
First of all, diamonds are all priced per carat. So, lets say a 0.50 carat diamond has a price of $1400 per carat. That diamondâs price for the stone would be $1400 * 0.50, or $700. Secondly, diamond prices per carat increase as you jump up to higher weight categories.ets say, for example, that you have a 1.55ct H color SI1 clarity diamond. The âRap Priceâ for that diamond would be $7,600 per carat. But finding the Rap Price for your diamond is only the beginning of pricing a diamond.
