A section of a seed head with raindrops on it - and a few moves with PS - reminded me of a song we used to sing in assembly when I was a child - Daisies are our silver
Buttercups our gold
This is all the treasure we can have or hold.
Raindrops are our diamonds
And the morning dew
While for shining saphires we've the speedwell blue.
Can't imagine youngsters singing that these days, but I do agree that raindrops sparkle like diamonds
