Topaz

This ex-matrix, complexly developed Topaz crystal is from the classic Volodarsk-Volynskii granitic chamber pegmatites in Zhytomyr Oblast, Ukraine.  The termination and all but one prism face are perfect, save for some very minor bruises, and aptly shows-off one the many complex habits Topaz is known for.  The outer surface is quite frosted, but where the crystal faces are broken across the base and one face, a fairly gemmy interior is indicated.  The overall colour is somewhat complex; held to sunlight the crystal appears colourless, possibly, tinged very weak pale blue.  Away from direct light, and even against a pure white background, the colour is distinctly that of tan-champagne, and on peering into the crystal form its base, a peachy zone is observed.  This terrific specimen comes with a Lawrence H. Conklin  (New York) together with his label.
