Buying Guide: Key Purchase Considerations

  • Origin and authenticity: Burmese rubies are often highly valued for color and provenance. Look for Certificates Of Authenticity or lab certifications to verify origin and natural status.
  • Treatment status: Unheated and untreated rubies are rarer and typically command higher value, but they require careful documentation and expert appraisal.
  • Carat size and cut: Larger stones create more visual impact but may require specialized settings. Oval, emerald, and cabochon cuts influence color perception and wearability.
  • Color and hue: The most prized rubies exhibit deep red hues, with pigeon-blood coloration considered highly desirable. Lighting can affect perceived color.
  • Budget vs. design goals: Natural rubies with certificates provide confidence but may vary in price. Lab-created options offer consistent color and lower risk for certain designs.
  • Care and handling: Rubies are durable but still require proper mounting and maintenance to preserve color and avoid chips.
  • Certification and return policy: Purchasing from reputable sellers with clear return terms helps protect your investment.
  • Practical design considerations: Larger stones suit bold centerpieces; smaller stones or matched sets are ideal for multi-stone designs or healing/energy-focused projects.
  • Ethical sourcing: Consider suppliers with transparent sourcing practices and certifications to ensure responsible mining and handling.
