One of the earlier cuts of diamonds - the table cut - punctuates these remarkable early enamel earrings.

Dating to the late 17th century, and formerly buttons, they have been converted into wearable earrings. Typical of that period, black and white enamel was favored, here adorning a star pattern that decorates the raised dome.

Repousee enlivens the domed surface with "bubbles" of raised gold, then the inky and ivory enamel dots the top. At the apex, a flat table cut diamond was set, closed backed, and with rub over gold.

This technique takes the fantastic properties of gold (it can be spread incredibly thinly yet retain strength) and smears this precious metal over the edges of the diamonds.

The gold work is a miniature marvel, high domed and textured – and the color is rich and sumptuous.

A crimped edge finishes the circle. Later 14k shepherd's hook ear wires were added for security. Yes, these have survived for over 300 years!
