For a complete answer, you must go to this site:RarityOf the 4 C's, Carat Weight is probably one of the most important considerations with respect to rarity, value, and consumer preference. In fact, Carat Weight, or how much the diamond weighs is the most significant value factor in a diamond. Because diamonds by nature are rare, a 2 carat diamond is actually about 3 times more valuable than a comparable quality 1 carat size. Statistically a 1 carat is one in a million diamonds mined, and a 2 carat is one in five million diamonds mined. Therefore, all things considered a 2 carat diamond is really "value priced" based on the rarity factor.PricingLarger diamonds are much more rare, thus commanding a higher price/per/carat. Carat weight affects the value of a diamond by about 10-20% for each step in size difference. Also, "magic sizes" refer to major carat weight categories, for example exactly 1.00 carat, or larger, and can prompt "price premiums". To calculate the price of a diamond you multiply the carat weight by the price/per/carat. For example: if a 1.25 carat diamond was priced at $10,000 per/carat the diamond would be sold for $12,500.* http://www.diamonds.com/education/Carat.aspx
