How to Assess the Quality of Natural Round Sapphires

When selecting natural round sapphires, jewelers and buyers should evaluate the 4Cs:

1. Color

  • The most valuable sapphires have rich, evenly distributed color without zoning.
  • Vivid blue, pink, and yellow are among the most sought-after hues.

2. Clarity

  • Sapphires naturally contain inclusions, but high-quality round sapphires should be eye-clean (free of visible flaws).
  • Excessive inclusions can affect transparency and brilliance.

3. Cut

  • A well-cut round sapphire should have perfect symmetry, proper depth, and well-proportioned facets.
  • The precision of the cut impacts the gem’s light performance, enhancing its sparkle.

4. Carat Weight

  • Due to their depth and faceting, round sapphires may appear slightly smaller than other cuts of the same carat weight.
  • However, precision cutting ensures optimal fire and brilliance.

A well-cut round sapphire enhances light performance, making it the most brilliant sapphire shape.

Heat-Treated vs. Untreated Round Sapphires

1. Why Heat Treatment is Common

  • Heat treatment enhances color intensity and clarity, making sapphires more visually appealing.
  • Most high-quality round sapphires on the market have undergone low-temperature heat treatment to improve their appearance.

2. Pricing Differences

  • Heated Round Sapphires – More widely available and affordable, with enhanced brilliance.
  • Untreated Round Sapphires – Extremely rare, commanding premium prices due to their natural state.

3. Importance of Certification

Buyers should always request gemstone certification from reputable labs like:

  • GIA (Gemological Institute of America)
  • AGS (American Gem Society)
  • GRS (GemResearch Swisslab)
  • Other Local Gemstone Laboratories that are highly reputed

Certification confirms whether a sapphire has undergone heat treatment, ensuring transparency and authenticity.
