This beautiful orange zircon is from Nigeria. The original gem rough was a very dark red, appearing almost black in most lighting. Gentle heating with a butane torch for a few seconds turned the stone this gorgeous rich orange color. The treatment is permanent and has no adverse effects on the stone whatsoever; this type of heating is quite common with zircon. The gem weighs 2.37 carats and measures 8.2 x 8.2 x 5.0 mm.
