I'm not sure how to describe the patterns in this nifty Noreena Jasper rectangular cabochon. Yellow fire? Spectrum analyzer plot? It's just different. This cab looks good oriented in any position. I'm going to keep this one, so I'll orient it in the display cabinet...

29mm x 13.5mm x 3mm.   Weight: 13.50 carats.
