Enhancement Techniques

Techniques to enhance color and reduce the visibility of flaws are frequently used on this stone. Unfortunately, this gemstone suffers from a strange misconception that it is a synthetic or man-made stone rather than the lovely natural creation that it is. Perhaps, this misconception is due to the fact that they are frequently treated.

These gems are regularly treated to alter color, as so often seen in the blue and colorless varieties (many might mistake the colorless form of this gem for diamond because of its strong brilliance). But, these stones also occur naturally like yellow, brown, orange and red color. For many years colorless stone was used to imitate diamonds. However, most of these gemstones, especially the blue and colorless forms, are enhanced by heat treatment.

Things to Remember

Upon prolonged exposure to sunlight, color of this stone darkens and its luster becomes dull. However, this effect can be reversed by giving the stones a second heat treatment.

You need to exercise care because it is brittle and will chip or abrade easily. For this reason, zircon is recommended for rings only if, set with a protective bezel setting.
