A Blue Gem Between Us

I am running to you, but there is a blue gem between us. Want to touch your hand - but gem doesn't let. It's as big as breast, it is dazzling, clear. and you just can't reach me when you're trying to penetrate. It's so big and cold, it is so silent. Is it someone's love? Is it someone's shield? It's concealing you, I can't see you, darling. Just to look at it from both sides - is bliss? I am running to you, but I flop in blue gem. Dazzling gem many-sided, of deep color, blue! And it makes me sober, its rays are exciting as the sky itself standing before you! It's too big a gem, and I can't embrace it. Its pride is immovable - I am helpless, small. Is it my true love or is it protecting? What is it here for? Where is it from?
