US guides
US shoppers should compare diamonds on the USD stone price first. Sales tax is a checkout question for the delivery state, not a reason one G color stone is “better” than another.
Two stones in the same carat band are ranked by cut, color, clarity, and origin. Adding an estimated tax in your head does not change which inclusion is under the table.
Whether sales tax is due, and in which state, depends on your ship-to address and how checkout is calculated. The listing price itself stays the diamond price in USD.
A United States domestic delivery is not the same as an import into another country. If you are shopping from the US for a US address, start with the shipping page rather than a duty calculator.
