Spiral Galaxy marble with blue veil cloud

This is one of my own designs of spiral galaxy marble, into which I've added a heavy layer of misty blue to create the illusion of interplanetary dust & gases to try and make it look more like something you would see with a telescope. In this spiral are glittering 'stars' with hints of pink, green, gold and white made with dichoic glass which sparkles as its moved.
Behind the spiral I've added whisps of blues and greens to create a distant nebula, and on the back of the marble I've used a high silver glass which creates tones of greens and blues.
The marble is just a touch under 43mm/1.69 inches across. There is a very slight flattened bottom where the final punty rod was removed. For my marbles I use high quality laboratory grade borosilicate (often known by the 'Pyrex' trade name) which is ultra clear to help create lenses & the optical illusion of space and distance. As this is handmade glass there may be some surface imperfections and/or bubbles in the glass
