Reflective of the mystery and allure that the moon's presence still holds for us today, this hypnotic blue-flash man in the moon ring is just as evocative.

Precisely carved and rendered, this serene moonstone face flashes with a distinct inner azure light throughout. At 10.7 mm in diameter or 7/16 of an inch, the moonstone itself is a good medium-scale cameo.

It is prong set, and just like the real moon sometimes does, it radiates with an aura, in this case of old mine cut diamonds. Their total weight of 1.26 carats and they send off a glittering ring of sparkle (color H-I, clarity VS).

Set in rub-over silver bezels, the diamonds are brilliant and chunky.

Even the ring's profile presents a regal look. A gallery of 18k yellow gold openwork with a series of geometric piercings that allows light to reach the gems and diamonds.

Strong flashed of blue work their magic throughout the face. This later 19th century ring is the creme de la creme of examples of this scarce finger adornment.
