Comment: Better than image sapphire with purple and yellow in a dark green blue basis. Shifting strongly to purple at night, while decisively greenish blue at day. Fancy blossom cut from Africa. Often surprisingly sparkling and lively, then again mellow and calm. Good untreated sapphire for individual jewelry on a budget.
