Zircon halos are a common inclusion in corundum, and are often found in many gemstones. This is a zircon crystal included in a faceted iolite with a rounded shape and surrounded halos consisting of small wings of fractures. Micrograph was taken with Gemscope GR7, and inclusions were confirmed with a Raman microscope.

This is an inclusion found in an aquamarine pear cabochon, with a flower-shaped pattern, which is actually a "hematite rose" observed in the direction of the basal plane. Such shapes or forms composed of regular and symmetrical pattern are usually called fractals geometrically. This photomicrograph was taken with Gemscope GR7 with 5MP electronic eyepiece at 100X magnification, and the inclusion was confirmed by micro-Raman(GR7).
