James Allen Review 2026: Is It Worth It?

The 360° Video Advantage

James Allen's signature feature is their high-definition 360° diamond viewer. For every single stone in their inventory — not just selected highlights — you can see a smooth, rotating video from multiple angles at up to 40x magnification.

This is transformative for online diamond buying. You can zoom in on the table of the diamond, look for any visible inclusions, assess the cut quality and brilliance, and compare multiple stones side by side. No other major retailer offers this level of transparency for their entire inventory.

Lab Diamond Selection

James Allen offers one of the largest selections of lab-grown diamonds online:

• Shapes: All major shapes including round, oval, princess, cushion, emerald, pear, asscher, radiant, marquise, and heart
• Carat range: 0.23ct to 5.00ct+
• Color range: D through K
• Clarity range: FL through I2
• Certifications: GIA, IGI, and AGS

With 150,000+ total diamonds in inventory and a significant percentage being lab-grown, James Allen almost certainly has the exact combination of specifications you're looking for.

Pricing

James Allen tends to be 3–8% cheaper than Brilliant Earth on comparable stones. Here's a snapshot comparison:

• 0.5ct G/VS1 Round Lab: $380–$520 (vs $400–$560 at Brilliant Earth)
• 1.0ct G/VS1 Round Lab: $1,100–$1,580 (vs $1,200–$1,700 at Brilliant Earth)
