Weight: 0.61 ct; size: 5.60 | 4.07 | 3.11 mm; shape: oval; colour: medium very strongly greenish blue; slightly greyish; clarity: eye clean; cut: very good; treatment: none.
Notes
Very clean specimen; very good mixed style cut. The colour change is mainly caused by relatively high amounts of vanadium (Schmetzer & Bernhardt, 1999). Source: David Weinberg, Multicolour Gems Ltd.
