My Little Moonstone

Brighter than the moon
Without you I feel like a loon
I will hold you close
Whenever I need you most
With your little rainbows
I wonder why I love you so
Your colours so creamy
You look so dreamy
Quite so small
But not like a ball
I found you when life seemed so hard
Piercing through me like a shard
So many people would call you a rune-stone
You are my little moonstone
