One of the more unusual Thomas Glenn Holidays designs is "Strata" - which is an interpretative look at the layers of the earth.  Rendered in glittery swirls of black, white, and silver, onlyone of these great ornaments remains available.  Side, top, and bottom views are shown here.  Once sold, the style will be removed from the website.
