Buying Guide
What to consider when choosing 1-2 carat diamond alternatives:
- Stone type: Lab-grown diamonds (IGI/SI) offer close-to-natural diamond properties and certification. Moissanite delivers higher brilliance and fire at typically lower cost.
- Color and clarity: For near-colorless looks, target D–F color and VVS1–VS1 clarity when possible, especially for rings and higher-end earrings.
- Setting and metal: Consider hypoallergenic options (nickel-free) like S925 silver with rhodium or 18K plating, and prong settings that secure the stone.
- Certification: IGI or IGI-certified stones provide traceability. For moissanite, the certification may emphasize color and fire rather than carat accuracy.
- Fit and comfort: For rings, verify size and band width; for earrings, ensure secure backings and a comfortable weight.
