If you like super cool marbles for your collection with a story behind them, then this is the marble for you, and I suggest buying "Deep Twist" to go along with it! Why you might ask? Because this marble is the other half of Deep Twist! What Nate does with many of his marbles is to make a fumed implosion, and then slices it in half with a glass saw. He then takes those halves and turns one, or sometimes both, of them into marbles! These 2 marbles look so similar because they are the two halves from one implosion - how cool is THAT. On top of that, you've got that beautiful polished tear drop opal in there. I've got a pair of these in my collection - you need a pair in yours!
