Constantine S

I obtained this several years ago from an Eastern European seller with no background at all about it. I thought it might be connected with Eastern Orthodox or some sort of award. I've been told by several Masonic appraisers it is not Masonic. I've seen this particular double-headed eagle before somewhere, but no longer have a clue where. Thanks for any help no matter small or hunch. All suggestions and referrals welcome.  

Have been trying to identify this for a very long time...
Obtained from Eastern European knowing nothing about it. I consider maybe connected with a Greek Eastern Orthodox Church. 
Solid brass Double-Eagle wearing 2-crowns, wings projecting up, surrounded by wreath, 8-point star (Redemption/God?) above with 2-winged angel/cherub affixed; no markings anywhere, and back is blank.
