No heat
The report records no indications of heating. For an orange sapphire, an unheated origin is the exception rather than the rule.
Colour stability
Laboratory colour-stability testing has been completed and the colour is considered stable.
A reference specimen
At 4.97 ct the stone is modest in weight, yet the combination of unheated origin, stable colour and clean crystal makes it a reference specimen for its variety.
