Note: "Gold-In-Quartz" Jewelry is so-named because in includes pieces of the as-mined quartz bearing gold veins first discovered during the California "gold rush" of the mid 1800's. This jewelry became very popular after the discovery and spawned a "niche jewelry" industry featuring native California gold nuggets and gold-in-quartz specimens. Although modern gold-in-quartz jewelry is still produced, this piece is emblematic of Victoria era style as it incorporates other contemporaneous design elements, such as black enamel tracery and the Greek key design motif.
