This week’s image is a yellow color zone of sapphire with a visually striking elongate planar cloud consisting of whitish, polka dot-like inclusions, as well as minute spots. Like a localized rain shower, these particles cascade across the interior of the yellow sapphire. Inclusions such as these can exemplify the diversity of features we find inside gemstones.
In 2014, AGL had the opportunity to examine some bicolor, blue, yellow, and green sapphires from Kina, Kenya.
The photomicrograph was taken by Christopher P. Smith; magnified 50x.
