This is a beautiful brooch/pin from Lenox.  It was created using their iconic ivory color on a porcelain base.  The brooch features a three leaf clover or shamrock with Celtic knots on the stem and each of the leaves.  It is out-lined or trimmed in a thin gold line.  At the center you will find a faux emerald green rhinestone (some have this listed as a Swarovski crystal?).  The back is clearly marked "LENOX". It measures approximately 1 5/8 inches long and tall.  Brooch is in good vintage pre-owned condition.  Light surface wear is present.  Pin back is secure.  Please review and enlarge all photos for additional details, views and measurements. Shipped via USPS Ground Advantage.
