Material: Zircon. These gems are described as beautiful lab-created stones, offering a red color similar to garnets at a good price.

Buying Guide: Key Purchase Considerations
- Stone type and appearance: Decide between moissanite for diamond-like brilliance, sapphire-like blue, ruby-like reds, or general lab-grown corundum for color variety. Consider whether you need certificate authentication (GRA/AGL) for added assurance.
- Size and cut: Match jewelry design needs with size options (e.g., 5x7mm, 8x12mm, 16x12mm). Oval and round shapes offer different setting requirements and facets that affect sparkle.
- Color and clarity: Lab-grown stones often have fewer inclusions and consistent colors. If you must avoid inclusions, prioritize stones with higher clarity grades or official certificates.
- Certification and provenance: Certificates (AGL, GRA) help verify authenticity and enable diamond-pen or software-based verification. Ask for certificate details when available.
- Budget and use case: For inlays or fashion jewelry, budget-friendly options like zircon-based red stones may suffice. For heirloom-inspired pieces, prioritize certified moissanite or sapphire alternatives.
- Care and durability: Moissanite and corundum are durable; consider hardness ratings and cleaning needs when selecting stones for rings or bracelets.
