This is a stunning Imperial Topaz from Mexico. The color is difficult to describe precisely–a rich burnt orange with hints of red and brown–and it shifts slightly with the lighting. I was able to get just two pieces of this rough from very old stock that I found while digging through dozens of old boxes. While some orange topaz can fade with exposure to sunlight, this topaz has been stable as I’ve exposed it to significant sunlight with no noticeable fading. The color actually shift slightly with the lighting. In daylight and incandescent light the gem shows a stronger red tone to the orange tones; under fluorescent light, it shifts to a more pure orange tone.
This gem was cut in my “Scintilla” design and weighs 4.21 carats, measuring 10.5 x 7.6 x 6.5 mm.
