Dark, very dark blue-green base with shadows of something swirled within, brushed with, in some light a dry looking, thin white, layer of color. In other light, the white almost disappears, leaving an almost, acid-etched looking surface. A metallic, has been suggested. There is no shine on the surface where this... whatever is applied. The rest of the marble surface is very shiny and there is no hint of color, other than the dry white, in certain light, mentioned earlier, I see no seams, no manufacturing marks, no deformation of any kind, whatsoever, and a fairly, nice spherical shape. It is a larger marble in the vicinity of 3/4... 13/16th's...... I just dropped it on the carpet and don't know where it rolled off to...... Looking again, backlit... The blue is more of a gunmetal, blue with maybe a hint of green. The base glass is extremely, dirty looking. There are clouds of like black smoke, bulging out from the center, and a dirty, polluted looking swirl curling through the, I believe it's called "seedy" looking glass. Dirty bubbled frothy. It don't look like it would taste very good at all... The polluted looking swirl has brown and green in it, I think... Well???
