Diamond Price Guarantee

The Blue Nile Diamond Price Guarantee makes it easy to purchase diamonds with peace of mind. If you find a comparable GIA certified diamond at a lower price, call 888-565-7641. If the offer meets our qualifications, we’ll match the price. There is no comparison when it comes to the value and quality of Blue Nile diamonds. The following terms and conditions apply to our Diamond Price Guarantee program.

Diamond Price Guarantee Guidelines

• Diamond Price Guarantee is a free service and only takes a few minutes to get started.
  Simply contact Blue Nile at 888-565-7641 with your diamond quality and price specifications. A Diamond & Jewelry Consultant will locate a matching Blue Nile diamond. In most cases, Blue Nile expects to have the lowest price. In those cases where the competitor's diamond is less, Blue Nile will match the lower price.


• No sales pitch.
  Blue Nile Diamond & Jewelry Consultants do not work on commission, so there's no pressure, no sales pitch. We simply want to provide you with the best possible diamond at the best price.


• The exact diamond.
  To ensure accuracy, the Diamond Price Guarantee program requires that diamonds be graded by the Gemological Institute of America or the American Gem Society Labs. Diamonds will be compared according to the Four Cs – cut, color, clarity, and carat weight, as well as additional criteria such as fluorescence, polish and symmetry, table and depth percentage, etc.

To get started, simply contact a Diamond & Jewelry Consultant at 888-565-7641.
