This is an interesting handmade belt buckle.  I believe the main material is horn, with a turquoise stone decoration.  There is a smooth lacquered wood inset on both sides which has a nice grain and color.  It is set on what I believe is brass. There is a sticker on teh back which says #203 Wilderness. Weighs 133 grams.  

NOTE: I am not a jeweler or gemologist. I do my best to describe pieces accurately.  Most of the jewelry I'm listing is gently used or vintage. Most have been jewelry of my own - it's time to downsize!  One should expect some sign of wear, and if flaws are seen, they will be pointed out.
