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 1 800 425 022 with your diamond quality and price specifications. A Diamond & Jewellery 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 & Jewellery 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 Gemmological Institute of America or the American Gem Society Labs. Diamonds will be compared according to the Four Cs – cut, colour, 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 & Jewellery Consultant at 1 800 425 022.
