Personal Note From Natural Gems Belgium:

This unheated, certified Natural ruby has a high-quality color grade and is very well cut and fair to good polished. Its deep red color and good luster make it a valuable gemstone.
We indicated the Gemstone clarity I1 due to a small chip under girdle, only visible with magnification. The chip in reality does not influence value
