This borosilicate implosion marble is 1.94 inches in diameter and has a star cluster milli cane as the centerpiece that I pulled myself. I always call the latticino stringers colorful worms. 🤪 I love the color combinations inside them. I believe the purple one has royal jelly in it which is a much sought after color in borosilicate. It’s got some dichroic glass in the background and is backed with some blue stardust. All my marbles came with a 3D printed marble stand and I’m offering free shipping right now on web site orders.
