The curls in this beautifully colored marquise shape malachite stone are echoed in the ribbon curls of 18k yellow gold in the custom mounting.
The pendant/pin/brooch has a bail, and a vintage trumpet style pin clasp in back.
The pendant is 35 x 45 mm (about 1-3/8″ wide and 2-1/8″ with bail). The malachite marquise stone is 14 x 40 mm (about 9/16″ x 1-9/16″).
The tube hinge and trombone clasp date this pendant brooch to the late 1800’s.
Note: The bail is not truly collapsible, so it is possible the bail was added at a later date.
Not marked, but acid tested positive at 18k gold.
Weighs 14.4 grams.
Very good vintage condition.
