Blue Nile stands out as a premier online jeweler offering a diverse and expert-curated product lineup. Here’s a breakdown of their highlights:
1. Natural & Lab-Grown Diamonds
- Extensive selection: Browse over 100,000 independently graded natural and lab-grown diamonds—available in all classic shapes (round, princess, cushion, emerald, oval, pear, and more) with GIA/IGI certifications.
- Lab-grown benefits: These diamonds share the same optical and chemical properties as mined ones, offering an ethical and more affordable alternative—with equal longevity and sparkle.

2. Engagement & Wedding Rings
- Customizable designs: Choose a loose stone and pair it with settings in platinum, yellow, white, or rose gold—including solitaire, halo, vintage, pavé, split-shank, three-stone, and designer styles.
- Ready-to-ship & Creative Studio: Both pre-made and fully personalized designs are available. Blue Nile’s Creative Studio guides you through every detail—from the 4Cs to metals, engravings ($30 fee), and ring sizing.
3. Fine Jewelry Collections
- Necklaces, bracelets, earrings & more: Signature collections include fine pieces with natural or lab-grown diamonds, colored gemstones (sapphires, emeralds), birthstone series, designer collaborations, and everyday wear items.
- Lab-grown highlights: Standout products like the lab-grown diamond eternity band, floating solitaire pendant, stud earrings, and channel-set bangles offer brilliance and value—to say nothing of being ethically minded.
