Icons manufactured by a Russian supplier using their proprietary process of applying successive layers of color and metallic-like patterns resulting in a brilliant, detailed, and nearly three dimensional appearance.(Note: The photograph of this icon will be updated soon. Actual icons now have reflective silver/gold backgrounds and halos instead of the muted silver background colors shown in this old picture)
