The Blue Nile website is designed for ease of navigation, with advanced filters for:
- Carat
- Cut
- Color
- Clarity

- Fluorescence
- Polish/Symmetry
A 3D viewing tool allows customers to rotate and examine diamonds from multiple angles. You can also view high-definition videos for many diamonds, giving a near in-person experience.
Build-Your-Own Ring Tool
Blue Nile’s customizable ring tool is one of its best features. Users can:

Competitive Pricing
Blue Nile is known for competitive pricing, thanks to its direct-to-consumer model. By avoiding the overhead costs of physical retail stores, the company can offer diamonds at significantly lower prices than traditional jewelers.
They also offer price-matching, meaning if you find a diamond of the same specifications at a lower price from a competing retailer (with the same grading certificate), Blue Nile will match it.
