14k rose gold and diamond.
The ring was cast using a cuttlefish bone mold. It is rose gold (an old fashioned mixture of fine gold and copper). This is probably closer to 18k, I mixed it some time ago. It will require measuring.
The diamond, a 2.6mm stone, is flush set. The photos here are before the ring was cleaned. After the cleaning the stone glistens nicely.
Fabricated Sterling. Approximately 2 1/2 inches.
This is my take on the traditional Bavarian/Austrian hat pin. I altered the traditional shape and the fastening mechanism.
The pin is designed to hold either a feather or a bundle of hair (goat and badger are typical). It is held in place with a screw.
The downy feather is from a peacock. I found it at a zoo.
Here is the pin and its pieces.
The threaded points are inserted into the hat, and the round nuts secure it from inside the hat.
