Thomas Glenn Holidays is noted among many jewelery and high-end stores for their designs of "Faberge" eggs.  Slightly larger than a standard ball ornament, the egg design is very popular among collectors.  This early design, now retired from the active collection, shows a beautiful silver ornamentation set against a light green background.  The second image here shows the bottom of the egg with an intricate twelve-point star design.  Only one of these great ornaments are available, and once sold, will be removed from the website.
