Sapphire purple 5.78 ct
Sapphire with a weight of 5.78 carats with good clarity. The purple color is rarely found in the mineral corundum. Coloring consists of two components: blue and pink-purple colors, so they can be present in the sample as additional shades. Sometimes this shade is the result of refinement, in particular heat treatment, in rare cases it appears in stones with a color change effect.
