Beautiful vivid red pigeon blood ruby of 3,39 ct. from Mozambique as it is indicated on the GRS report. Rutile needles play with rainbow colors in a very delicate softness. Parallel ribbons cross the gemstone. Very well cut gemstone. 
GRS Report nr. GRS2014-0412313 of 29 May 2014. This stone is so exceptional that the GRS Laboratory added an appendix to the orignal report and to mention that it is a GRS-type pigeon blood ruby (without strong fluorescence). No indication of thermal treatment.  
​Dimensions : 8,37 x 7,68 x 4,61 mm. 
Munsell Book of Color : 
Primary hue : 5R 2/8 et 6.25R 3/12
Secondary hue : 7.5R 2/12 et 2.5R 4/14 

Expert notes :
The very thin needles of rutiles are in 3D. They occupy the stone throughout its depth and cover the space alongside the suspended tiny crystals. There is no need to look through the microscope, the magnifying glass x10 will place you at the forefront of the stone’s performance.
