IMPERIAL RUSSIA - CRIMEAN WAR 1853-56 SILVER CROSS FOR THE CLERGY

This cross is made of silver and it is a bit mystery to me. In the book by A. Kuznetsov "Awards" under number 588 there is a "Cross in memory of the East War" (this is what it was called back then) in dark bronze. The cross was awarded to all priests and bishops who served in the church during the war time. 
Under the 589 there is gold version of the cross. I have never seen one single piece in gold ever. May be unique.
The silver version is not mentioned. And I also never saw it before I acquired this piece. 
May be a fantasy award based on the bronze or may be a true period piece. I don't know that. 
Please, judge by the pictures.
