Highest Diamond Quality

As the largest online diamond retailer, Blue Nile offers the largest collection of the world's finest cut diamonds. Pre-selected for exceptional quality, the cut, colour, and clarity of our loose diamonds are evaluated based on a standardized grading scale. Also, each loose diamond is accompanied by a grading report from either GIA or AGSL, independent diamond grading labs with the most stringent grading scales of all labs.

Our diamonds are pre-selected for quality

Diamond Jewellery

Diamond Jewellery

For exceptional quality, the diamonds set in our diamond jewellery meet strict minimum quality standards. Each diamond is colourless to near-colourless (D–I grade color) with exceptional clarity (FL–SI grade clarity). This standard of quality applies to all our diamond jewellery — even pieces with the smallest diamonds.

Black diamond fashion jewellery is crafted using natural diamonds that have been treated to create the unique black colour with a high lustre. It is common for black diamonds to reveal minor surface imperfections without magnification.
 
Pearl Jewellery

Pearl Jewellery

The pearls in our Akoya cultured pearl jewellery must have high to medium lustre, and they must be mostly round in shape, with smooth surfaces and no noticeable blemishes. Since colour and size are the most important features of Tahitian cultured pearls, ours feature high to medium lustre, they must be mostly round in shape, and have smooth to lightly spotted surface markings. Even our Freshwater cultured pearl jewellery features white pearls with high to medium lustre, round to slightly off-round, good uniformity, and smooth to lightly spotted surface markings.
