I have another question about the matte vs shiny marbles. I posted the one on the right earlier asking what type it was as the bottom white made it fall outside of the tiger eye ID chart I have, but we know Vitro likes to throw in curve balls all the time, so there's that. I have found another marble which sports the same colors, except it doesn't have white at the bottom pole. The colors in both marbles are virtually the same. Both are 1/2", both are on a clear base. The difference is the first one (on the left) is shiny and the 2nd one on the right has a definite matte finish. This just seems to be done on purpose at the time of production. Either way, I'm thinking Tiger Eyes on both just due to the construction of the shiny one. What say you experts?
