It is soooo hard to pick favorites when it comes to Yoshi's masterpieces - I literally LOVE THEM ALL!!! But hey, if I had to, I'd have to say this is one of my very favorites ever. I don't think I even have to say much about this marble, because the pictures pretty well convey what I'm thinking. You've got contrasting STUPENDOUS opals on either side, one square, one round, and each one is ensconced in a gorgeous glass bowl (if I can call it that). Then between this, you've got the layer after layer of sweet dotted goodness, typical mind-boggling precision. But to top it alllll off, you've got Yoshi's incredible spider pattern right at the forefront of the dot work, and WOW, do I loooove this pattern. I want to grab every marble that has this on it, because it is SO VERY COOL!!! The colors, the patterns, the fire in the opals....the spiders - this marble has it ALL, and is one crazy astounding MASTERPIECE. Do NOT miss this one!!
