0.70 Ct. Yellowish Green Sapphire from Madagascar

A luminous, transparent round yellowish green sapphire weighing 0.70 carat, this gemstone measures 5.13 by 5.02 by 3.50 millimeters, and presents a mixed brilliant cut that maximizes scintillation and fire. The intense color intensity is immediately arresting, a living green with golden undertones that shifts with every motion, offering warmth and freshness without overwhelming brightness. Clarity is graded very slightly included, evaluated at eye level, which means the stone is beautifully clean to the eye while retaining character under magnification, and an excellent polish amplifies every facet interaction with light.
