Very shimmering natural purple red spinel of 8,09 ct. from Burma (Myanmar) as mentioned in the GLC report. Very well executed square mixed cushion cut allowing a beautiful play of light. Great transparency and uniformity of the bright color, and yet with a delicate silkiness. No mention concerning the treatment in the report. 
GLC (Thailand) report nr. A77992 of June 16, 2020.
Dimensions : 10,97 x 11,27 x 7,67 mm.
Munsell Book of Color : 
Primary hue : 10RP 2/6
Secondary hue : 10RP 2/8
Tertiary nue : 10RP 5/12

Expert notes :
This spinel has no less than three colors on the same page in the Munsell Book of Color. What does this mean? We are confronted to a stone that has developed strong nuances in the same tonality. A declination on the same theme is not common.
