Dates to the Victorian era, circa 1900.
Crafted with a 14K gold pin stem, and a natural nugget in quartz, which tests around the 21K gold range.
This fabulous nugget bears its natural rock still (Ie. It hasn’t been processed or refined.), and may well have been a personal treasure that was later converted into a pin, as it was fairly clearly not a mass produced piece. (This can be seen by the way that the pin stem was attached.)
The stick pin measures 1.97” from end to end, while the nugget's top portion measures 0.47” by 0.41”. This piece weighs 3.61 grams.
Condition is very good, with no damages or repairs.
