Did The Members Of The Knights Templer Ever Wear A Ring With A Skull And Cross Bones Set On A Triangle The Letters B K S Above The Triangle And Tiny Diamonds Set Along The Sides Of The Triangle??

I found a gold ring like I discribed, and thought it might have belonged to a member of the Templer order or one like the Templers. It is a small size and appears to be very old. Any information would be of great interest. Thank you in advance.
