Natural sapphires rank 9 on the Mohs scale (compared to diamond’s 10), making them extremely durable precious stones suitable for everyday wear. While diamonds typically command higher prices per carat, high-quality sapphires often provide better value retention and investment potential, especially rare, flawless specimens from prestigious origins.
The value of genuine sapphires is primarily determined by color intensity, clarity, carat weight, and origin. GIA certified stones from conflict-free sources like Kashmir, Burma, and Ceylon typically command premium prices, while factors like treatment status, cut quality, and overall aesthetic appeal significantly impact the final cost of these rare gemstones.
Heat treatment is the most common enhancement, improving color and clarity in natural sapphires while maintaining reasonable value. Untreated, pure sapphires command significantly higher prices—often 30-50% more—than treated stones of similar appearance. Diffusion treatments and beryllium treatments dramatically reduce a stone’s worth compared to high-quality natural specimens.
Corundum gemstones (sapphires and rubies) are prized for their exceptional hardness, making them perfect for everyday jewelry that maintains its beauty over generations. Their remarkable range of colors, combined with their rarity and proven value retention, makes purchasing these real gemstones both an aesthetic choice and a worthwhile investment compared to other precious stones.
