There is no set formula for the pricing of precious gemstones bases on a value to carat-weight/size ratio, but as a rule of thumb, the larger a gemstone is, the rarer it is, causing an exponential increase in price, According to Tavernier's Law the calculation for determining the price of a gemstone is: Wt2 x C = Gemstone Price

Wt is carat weight of stone, C is the cost of one carat of same quality gemstone.

Of course this is not an absolute price solution, but is a good price indicator.
