13.37 Ct. Spinel from Ceylon (Sri Lanka)

This beautiful transparent 13.37 carat oval blue spinel measures 15.26 by 12.86 by 9.27 millimeters, and it has been expertly faceted with a mixed brilliant cut to balance weight retention and optimal light performance. Clarity is graded as very very slightly included, evaluated at eye level, which for an item of this size means exceptional visual purity and minimal impact on brilliance. The medium intense color intensity presents a refined blue that is both lively and sophisticated, and the excellent polish ensures superior light return and scintillation across the table and crown facets. Origin is Ceylon, Sri Lanka, a provenance long associated with fine spinel material, and importantly this specimen is presented with no enhancement, confirming its natural color and structural integrity. For the discerning buyer, these combined attributes create a gemstone that reads as both rare and desirable, with a level of finish and optical performance that will translate beautifully in high end jewelry settings.
