US guides
United States shoppers compare diamonds in US dollars. A useful comparison holds shape, carat, color, clarity, and origin still, then reads the live USD price.
A 1 carat lab-grown diamond and a 1 carat natural diamond can share a color and clarity and still sit in different USD bands. Filter origin first so the sort order means something.
USD prices on Carat Mate are for the loose diamond. A US jeweler’s setting is extra. Sales tax, if it applies to your state and checkout, is not a reason to ignore the diamond price — it is a separate line from the grade you are buying.
Blog averages for “the US price of a 1 carat diamond” lag the market. Open the live listings in your carat band and compare those USD numbers.
