This beautiful golden yellow zircon is from Tanzania. The original gem rough was a brownish-yellow color often referred to as “honey” zircon. Gentle heating in an alcohol burner for a few seconds turned the stone this gorgeous rich golden yellow 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 5.25 carats and measures 9.5 x 7.7 x 6.9 mm.
