Gems: FAQ

How do I ensure the gemstone size is correct for my jewelry setting?

Always verify the dimensions in millimeters (mm) rather than relying solely on carat weight, as different gem types have different densities. Check the seller's technical drawing to ensure the depth and diameter match your setting requirements.

How can I verify if a gemstone is real or synthetic?

Look for listings that include GRA, GTC, or NGTC certification images in the product description. For high-value stones, prioritize sellers who offer 'Certificate of Authenticity' and check user reviews for thermal tester results.

What quality indicators should I look for in loose stones?

Focus on the '4 Cs' with an emphasis on Cut and Clarity; look for 'VVS1' or 'IF' ratings for maximum brilliance. Ensure the 'Cut Grade' is listed as 'Excellent' or '3EX' to guarantee the stone reflects light properly.

Are gemstones safely packaged for international shipping?

Reputable gem suppliers use vacuum-sealed bags, padded plastic gem jars, or velvet-lined boxes to prevent scratching. Always choose 'AliExpress Standard Shipping' for better tracking and insurance on fragile mineral shipments.

Recommendations for buyers

  • ✓
    Certification Verification
    Always prioritize stones that come with a physical or digital certificate from recognized laboratories to ensure the stone's origin and treatment status.
  • ✓
    Understanding Material Origin
    Differentiate between 'Lab-Grown' (chemically identical to natural) and 'Simulated' (different chemical structure) to ensure you are paying the correct market price.
  • ✓
    Refractive Index and Fire
    Check the technical specs for the refractive index; for example, Moissanite has a higher refractive index than Diamond, providing more 'fire' or rainbow flashes.
  • ✓
    Bulk vs. Single Stone Pricing
    For small accent stones (melee), buying in 'parcels' or lots significantly reduces the price per carat compared to buying individual pieces.
