This sapphire center gem comes from the Umba region in Tanzania. This region is known for its multi-hued sapphires, garnets and tourmalines. These rich gem deposits follow the undulations of the Umba River in the Tanga region. Sapphires are found in the most incredible hues of blues, greens, purples, pinks, yellows and orange. Many of these sapphires contain a number of inclusions that give the gems their color as well as character. Though sapphires from around the world are routinely heated, ANZA Gems does not heat sapphires, which would remove many of the internal inclusions and sometimes brighten the color. What you see is literally what you get right out of the red dirt in East Africa.
