I've finally worked up the interest to get involved in this drop but can someone give a list of which caps are transparent and which are not? They look cool, but for me I kind of want to see the lighting effect in the prism to justify the $20 price point. I'm particularly interested in the Onyx one.
Also can someone say which option is the dark grey one? I suspect it is the "spinel" cap, but the color options photo makes that option look almost cream colored.
