The Cap: The top of the acorn is iridescent, amber-colored glass with a ribbed texture. The Nut: The body of the acorn features a green and white "spatter" or "mottle" glass technique, giving it a textured, organic appearance. 9.2 oz without packaging. Gorgeous iridescence! Very MCM though no markings so I’m only guessing! 3.75” x 2.5” at the cap Feel free to ask any questions.
