Best for Lab Diamonds
Lab-grown diamonds offer identical physical and chemical properties to natural diamonds at a fraction of the cost. The best retailers in this category provide extensive inventories and transparent pricing.
- Clean Origin: A specialist retailer selling exclusively lab-grown diamonds. They are known for highly competitive pricing and an exceptional 100-day return policy. Read our Clean Origin Review.
- James Allen: While they sell both natural and lab-grown stones, their lab diamond inventory is massive. Their 360-degree viewing technology makes them a top choice for inspecting stones online. Read our James Allen Review.
Best for Natural Diamonds
For those who prefer the tradition and rarity of earth-mined diamonds, these retailers offer the best selection of certified stones.
- Blue Nile: One of the pioneers of online diamond retail. They offer a vast inventory of GIA-certified natural diamonds and a highly intuitive search interface. Read our Blue Nile Review.
- James Allen: Again, their 360-degree HD imagery is invaluable when assessing the clarity and cut of a natural diamond, allowing you to see exactly what you are buying.
Best for Fine Jewelry
If you are looking for earrings, necklaces, bracelets, or fashion rings, these retailers offer excellent craftsmanship and stylish designs.
- Blue Nile: Beyond engagement rings, they have a robust collection of classic fine jewelry, from diamond studs to tennis bracelets, often at better prices than traditional brick-and-mortar stores.
- Mejuri: Known for their "everyday fine jewelry" approach, offering modern, minimalist designs in 14k gold and sterling silver at accessible price points.
Best for Custom Designs
When you want a piece that is entirely unique, these platforms offer the best custom design experiences.
- CustomMade: A platform dedicated entirely to bespoke jewelry. You work directly with a designer to create a piece from scratch, from initial sketches to final production.
- James Allen Custom Studio: Allows you to modify existing designs or build a completely new setting around one of their loose diamonds, combining custom design with their massive diamond inventory.
