This is a lovely untreated, natural color-change sapphire from a brand new mine in Mozambique. The stone is a pastel lemon/lime color in natural light and light bronze in incandescent light. As is characteristic of this mine, the stone has a few minor healed grown lines and needle inclusions. These do not affect the high brilliance and the stone has great sparkle. This is a very rare and unique piece that will make a fantastic ring or pendant.
