Natural Umba Sapphire Gradient

A curated set of four natural, untreated sapphires from the Umba Valley, arranged in a soft color gradient.

Each stone was individually hand-cut in a small octagonal brilliant style, allowing the collection to move through blue-green, champagne, pink, and pale golden tones. Together, the sapphires total 2.13 carats and offer enough variation to create a custom ring arrangement, pendant, earrings, or small multistone composition.

These are naturally included Umba sapphires. One stone contains a visible feather within the pavilion, although the inclusion does not dominate its face-up appearance. The set is priced and sold together.
