Hi Cato, if you're using a cell phone camera for these photos, it helps to use a more neutral/darker background color, gray or black, non-reflective surface. Also, when you're taking the photo of your marble, touch the marble on the screen, that tells your cell phone what to focus on, and then hold your phone as still as possible until you hit the 'take photo' button, hope that helps!

That looks like a nice Akro White Spiral. If the White is only on the surface and doesn't go down into the base glass, you could call it a Snake  

Nice Akro.

I added a non-reflective surface, sorry that should have been in the original post.

Cato, looking better!  I like to use a black cotton t-shirt as the background, there's no light reflection.
For me, it's been a years-long learning curve for getting photos that I like of marbles, it's almost an never-ending lesson in photography
