Item # TOP 03-610. Medium blue oval topaz, extra fancy concave cut on pavilion and crown. The extra fancy cut justifies the higher price than most similar gemstones of this weight. Size is 10mm x 8mm and the weight is 3.5 ct. This would make a beautiful pendant or ring. The white flashes are the reflections of white light reflected through the stone. This is a beautifully cut stone with no windows.
