vintage Rock Sharpe Libbey etched glass stemware, panel optic water / wine glasses

Crystal clear vintage Rock Sharpe Libbey etched glass water or wine goblets, panel optic bowls #2012 stems. I don't know this etch pattern, except to know that it's NOT Buttercup, which is the only named etch I know on this shape. If you know its name, please email me and let me know!

This is a set of four glasses, 8 1/4" tall. All in excellent condition, my pics don't do justice to this pretty floral pattern.
