Faceted Gemstone Red Ruby oval from Bangkok Thailand

This is a glass treated faceted Red Ruby gemstone from Bangkok, Thailand
Glass treating/baking is totally natural on B Rubies to cover scratches, and it is then baked to harden. No major treatment is done or heat treatment for color.
This is hand-faceted with a faceted low pavilion and low pointed culet (see video)
approx. 12 mm long by 10.5 mm across - would be great for a ring
5.105 ct weight

Will ship in a gem cup and box
