This is a highly unusual reverse hand carved crystal and sterling necklace by AMCO.
It is absolutely gorgeous. This would be an early piece at, or soon after their founding as it has classic Edwardian design aesthetics.
AMCO was founded in 1919, in Providence, Rhode Island by A. Micallef.
The company produced very fine costume jewelry and often used sterling silver and gold in their designs.
AMCO jewelry has since become a rare and highly-sought after collector's commodity.
The necklace features a single oblong crystal cabochon set in lustrous sterling silver.
While the top of the crystal feels wonderfully smooth to the touch, an engraved starburst on the reverse of the piece shines through beautifully.
Both sides of the sterling silver chain are attached to a single loop at the top of the centerpiece with lovely silver floral components.
The necklace joins with a simple spring ring clasp.
Each of the earrings features a single crystal cabochon identical to the one on the necklace.
They are set in an open-bezel so the reverse engraving can be seen clearly.
Classic screw-clips make the earrings easily adjustable and wonderfully comfortable.
The front of the hinges is accented with the same floral components that adorn the necklace.
With its graceful simplicity, this set just speaks of quality and elegance.
Some of the metal shows a light patination, though the set remains in excellent vintage condition overall.
