  • Violet sapphires get their distinctive color primarily due to the presence of trace elements within the corundum crystal structure. The key elements responsible for the violet to purple hue are vanadium and sometimes a combination of iron and titanium.
    *Vanadium*: The presence of vanadium in the crystal lattice of the sapphire contributes significantly to the violet or purple coloration. The exact shade can vary depending on the concentration of vanadium.
    *Iron and Titanium*: In some cases, the combination of iron and titanium impurities can also contribute to the violet hue. The interaction between these elements can produce varying shades of blue, purple, and violet, depending on their relative concentrations and the overall crystal chemistry.
