Unsigned HAR Vintage Maltese Cross Brooch Pin Black Enamel Gold Tone Rhinestone

I believe that this striking piece is from HAR which makes it somewhat of a rarity as Hargo Creations only produced jewelry from 1955-67.  There are signed versions of this but this one is unsigned.  Measures approximately 2.25" across.  Fastens with rolling clasp and pin.  Gold tone with black enamel, clear rhinestones and a large faceted black rhinestone.

Not signed but in great condition. See photos for details.
