This is a singular blue moostnone with electric blue flash from tip to tail.
Elongated to flatter the finger, this fine moonstone is an oval cabochon. Yet, not matter how you turn or twist it, cool blue sheen is evident.
Many moonstones possess small patches of that flash, this one spans the entire length and width of the gemstone.
At 2.90 carats of mystical magical glow (9 x 7 mm or 3/4 by 1/4") it is set in a sawtooth-edged bezel.
A twisted rope pattern frames the gemstone, and on the shoulders, beads of gold and more braided wire enhance the 10k yellow gold setting.
