This zesty delight, makes pies and teas taste just right. Though sour as a grumpy heart, it brings sunshine to a tasty tart.

My rings tell my age, though I cannot speak, you’ll find me in furniture, sturdy and sleek.

Born in the dark of a silent sea, A speck of dust is the start of me. Wrapped in ribbons of glossy white, I leave the ocean to capture light. No diamond's spark, no ruby's gleam, I shine as soft as a nighttime dream. A hidden treasure, a precious prize, Kept in a shell till I meet your eyes

I wear green armor, round and wide, With a ruby-red treasure locked inside. I’m full of seeds, yet I’m not a flower, And on hot summer days, I’m the coolest power. I grow on vines but never climb, I’m mostly water, but taste sublime. Crack my shell and you’ll soon see What am I?
