​What a brilliant sapphire. This unheated, Ceylon yellow sapphire was mined in Marapana, cut & polished in Ratnapura, Sri Lanka. Classic oval flower cut, "regular," unheated yellow color, which is averagely light in tone but with exemplary clarity, and of course, the flower cut, bringing out a superior, flawless, sun-like luster. It is very well priced for this quality and size and certified unheated by the GGTL (Global Gem Testing Laboratory, Sri Lanka).
