This aligns with the known hardness of corundum.
Regarding toughness, while not explicitly quantified in the provided data, sapphire is noted for its general durability. However, the sources caution that some gemstones, including sapphire (listed under a general statement about durable gems), are prone to breakage under certain conditions, emphasizing the importance of proper mounting and care.
Color, Clarity, and Cut
- Color: While blue is the most famous color, sapphire occurs in all colors of the rainbow except red (the red variety of corundum is ruby). The sources confirm this range, noting sapphire's availability in a spectrum of hues. The specific causes of color are trace elements (e.g., iron and titanium for blue, chromium for pink, etc.), but the provided chunks do not delve into this detail.
- Clarity: Sapphires often contain inclusions. While some inclusions can decrease value, certain types, like silk (rutile needles), can enhance the stone's color or create a desirable asterism (star effect). The sources do not provide specific clarity grading details but note that sapphire is a natural gem that can be found with various characteristics.
- Cut: Sapphires are cut into a variety of shapes to maximize color and brilliance. Common cuts include oval, cushion, round, and emerald. The choice of cut depends on the rough's shape and color zoning. The sources do not detail cutting styles for sapphire specifically.
- Carat Weight: Sapphires are available in a wide range of sizes. Larger, high-quality blue sapphires are particularly rare and command premium prices, though the sources do not provide specific price data.
