6.30 carat natural sapphire from Umba, Tanzania set in a 14k solid gold pendant. The stone shows a color change from steely to medium blue in most lighting to pinkish lavender under certain indoor conditions.

Unheated and untreated. Eye-clean, with minor rutile (silk) visible under magnification, consistent with natural sapphire of this origin and size.
Cut in a custom modified oval design oriented to the rough for strong light return and color presentation. Set in a 14k gold pendant mounting.
