Multicolour Spiral Galaxy space marble

Lovely spiral galaxy space marble, I've used a really colourful dichroic glass that gives lots of small glittering spots of colour in a dense tight cluster. There are magenta pinks, electric blues, elmerald greens, golds to coppers, and all these colours will shift colour and sparkle as its moved in the light. These are all real 3D effects locked into solid glass.
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 wonderful tones of blues with patches of a slight metallic hint.
The marble is 41.7mm/1.64 inches across. 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
