There are two versions bearing a gold Master Mason square and compass symbol (texture based).
The LARGE has a black cord and is presized to fit those large prefab male avatars.

The standard version will fit the smaller male avatars (or female Droit Humain and AFHR). It has a silver necklace base. http://www.slexchange.com/modules.php?name=Marketplace&file=item&ItemID=823462
Send me an IM if you'd like me to create FC or EA versions ... more regalia coming soon!
Both can be found in my Mainland Shop also: http://slurl.com/secondlife/Garda/240/158/73
