Developing this theme, a recent theoretical literature on urban growth con-trols abstracts from the market failures considered above and portraysgrowth-control policies as a way for landowners to raise their incomes (andperhaps their quality of life) at the expense of renters.
Origin: Brazil. Price per carat: $2,000.00. Enhancement code-N No evidence of heat or other enhancement. Example. Natural Imperial Topaz. Carat Weight: 14.9ct.
In our example, â20 belowâ $7,600 per carat is $7,600 * (100%-20%), or $7,600 * 0.80, which comes to $6,080. Then you need to multiply that price by the weight to arrive at the final per diamond price ($6080 * 1.55 = $9,424). Sweet Spots of Value. Now, take another look at the sample âRap Sheetâ from before.herefore, diamond prices increase exponentially with weight, since their prices increase both due to the increased weight and due to the higher price per carat for the increased weight category.
