"Blowing Kisses to the Moon"
If I confirm that the cabochon is indeed a moonstone, then I guess that the rest of the design of this piece is self evident.
The stone is 12mm in diameter and, typically, has loads of splits, cracks, flaws and flecks to scatter the light beautifully.
The blue is a fine layer of two colours of enamel, blended to give the variations in shades. I textured the silver underneath to give an extra sparkle to the finish.
The body of the pendant is 0.5mm gauge silver, so it feels very light and delicate and I've hung it on a 42cm (16") rubber cord with silver clasp.
The expression "blowing kisses to the moon" apparently comes from a 1930's music hall song.
The song is known by many names including "She Was Poor but She was Honest" and "It's the Same the Whole World Over" and there are umpteen variations. You may be surprised to know that the old music halls could be quite risque, apparently. The words or this song were always adapted, but they took even more bawdy twists and turns when it became popular in the Royal Navy during WW2.
The version that I know was sung in my local rugby club, and (dragging it back from distant memory) began:
She stood on the bridge at midnight,
So, not quite such a romantic reference as you thought, eh? But a nice phrase, anyway.
