The above price list is only a guideline. All prices are
per carat in US dollars and may vary with market fluctuation and availability. GIA
certificates are available at an additional charge. We are not responsible for
typographical errors.
• Look up the price per carat for the color and clarity you would like.
G SI1, 1.50 - 1.99 ct. is $11,925 per carat.
• Multiply the total carat weight by the price per carat 1.75 x $11,925 =
$20,868.75
• Due to a premium on specific sizes, you must check the notation directly above
the chart. On this specific chart it states that for 1.70-1.80 ct. tw. you must add
approximately 5% to the price of the diamond. Therefore add 5% to the total price of the
diamond: $20,868.75 x 1.05 = $21,912
This is the approximate price for a 1.75 G SI1 Round Brilliant Cut diamond. The price
will be slightly higher for well cut diamonds, and lower for poorly cut diamonds. The same
steps should be used to determine the price for any other diamond. A premium is added for
matched pairs.
