Here's a very nice ice blue tint NN Hemingray product nail knob. At least that's what I suspect these are is Hemingray made NN pieces. Colour is a very nice ice blue tint with a lot of nice bigger bubbles. There is a chip on the top ring of this piece that is 1/2" long with a thin flake stemming from the chip and chippage/flakeage on the lat base and up the side some. Displays VVNM from the front side. More pix on req. First mail to me. $8 + actual shipping.
