What Is Star Sapphire Gemstone Worth?

The typical price range for Star Sapphire Gemstone is $1,000 - $1,100 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The sharpness and centering of the star effect significantly impact the $1000-$1100 price range.
• Body color saturation and transparency levels within the blue corundum influence market desirability.
• The quality of the cabochon polish and the overall symmetry of the gemstone's dome.
• Historical provenance and the era of the setting, specifically items dating back to the pre-1900 period.

How to Identify Star Sapphire Gemstone?

• Look for the distinct six-rayed star pattern caused by light reflecting off internal rutile needle inclusions.
• Verify the material as corundum, which possesses a high Mohs hardness of 9.
• Examine the stone for a cabochon cut, which is essential to properly display the optical phenomenon of asterism.
• Check for natural silk-like inclusions typical of authentic Sri Lankan origin rather than synthetic alternatives.

History of Star Sapphire Gemstone

Star sapphires have captivated humanity for centuries, often associated with destiny and protection. Ancient cultures believed the star within the sapphire guided travelers and brought good fortune. These unique gemstones gain their star-like effect, known as asterism, from inclusions of rutile needles oriented in specific patterns, reflecting light in a stunning six-rayed star. The Star of Bombay, a famous 182-carat star sapphire from Sri Lanka, was given to actress Mary Pickford by her husband Douglas Fairbanks Sr. and later donated to the Smithsonian Institution.
