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.

Frequently Asked Questions

  • Do IGI certifications guarantee no inclusions? Certifications verify authenticity and general quality; they do not guarantee flawless stones but indicate grading standards and traceability.
  • Is 2 carat always the right size for a ring? Not necessarily. Carat size depends on finger size, ring design, and personal preference for scale and comfort.
  • Can moissanite be a durable daily-wear option? Yes, moissanite is durable and often more resistant to scratching than some natural stones, but always follow care guidelines for metal plating.
