Blue Nile proudly hosts the largest online diamond inventory, showcasing over 140,000+ loose diamonds in all shapes and sizes, from small ¼ carat diamonds to diamonds weighing over 20 carats. Their site promises a diamond for every taste and budget at the lowest online prices. All these diamonds are sourced by Blue Nile, which engages in contracts with diamond wholesalers worldwide. Each loose diamond comes certified with an AGSL (American Gem Society Laboratories) or GIA (Gemological Institute of America) certificate.
Driven by the need to provide diamonds at the lowest possible cost, Blue Nile will match the price of a certified diamond if it is found cheaper at another retailer.
To add to the authenticity and quality of their diamonds, Blue Nile ensures that each of the diamonds featured on the site is ethically sourced and conflict-free by subscribing to the “Kimberley Process,” which is an international tracking method to ensure the authenticity of the diamond from the mine to market.
