Turkish Color Change Zultanite(R) Minimum 1.05ct 7x5mm Rectangular Octagonal, Radiant Cut. Gemstone Mined In Turkey And Cut In Brazil.<br/><br/>Zultanite(R) The Sultan of Gems, Zultanite(R), was named in honor of the 36 sultans who ruled the Ottoman Empire, a powerful and important sovereignty that spanned three continents at its peak. The term Sultan originally meant strength and authority, perfectly describing this robust gemstone. First collected and faceted by mineral enthusiasts in the late 1970s, Zultanite(R) is an extremely rare variety of the mineral Diaspore that can contain color changing or color shifting varieties. Zultanite(R) owes its unique palette to the minute presence of manganese. Found in only one place in the world, Zultanite(R) is mined in Turkey's remote Anatolian Mountains at an extreme height of over 4,000 feet. Anatolia, which means `sunrise' in ancient Greek, is blessed with majestic and beautiful landscapes that perfectly complement such an extraordinary gemstone. The unique beauty of Zultanite(R) is its rarity, and natural earthy color. The Zultanite(R) Chameleon variety has contrasting colors, which change from kiwi greens with flashes of canary yellow under sunny skies to rich champagnes in traditional indoor lighting and raspberry hues in candlelight. Zultanite(R) other key characteristics are its saturation, sparkle and durability.
