Comments: This light purple to periwinkle, to lavender colored gem is a great little sapphire. It's perfect for anything from an accent gem, to the main stone of a custom ring, or even a stacker ring, which I am fond of for this size of sapphire.
It's uncommonly clean for an Umba sapphire. The color also shifts between different shades of purple in different light. I won't call it a color CHANGING sapphire, but it certainly travels the range from pink purple to blue purple.
