Here is a very large (but adjustable) and very finely crafted coral & silver concho belt by Navajo jeweler Rick Martinez from the Gallup area of New Mexico.  The belt has a full 12 matching conchos plus a buckle.  Each concho is quite heavy and is handchiseled & handstamped.  Further evidence that this belt is so well made is that each concho has two silver straps to hold them on to the leather strap.  The belt measures 46 1/2" from buckle to end of leather.  Each concho measures 2 1/4" long x 1 1/2" tall.  There are 12 conchos in all.  The buckle also measures 2 1/4" long x 1 1/2" tall but it is a square instead of an oval.  This is really a great buy for such a large belt.  It is signed "Navajo, R. Martinez, Sterling".
