About the Pin Oak collection from the artist’s website: “Our Pin Oak Collection celebrates the little acorns from which great oaks grow. The acorn is the harbinger of new life. Acorns were used extensively as a food source for Native North Americans, and also roasted as a coffee substitute. It is also important for local wildlife populations. The acorn fruit has been recognized in country medicine for relieving chilblains and frostbite.” About the materials for this piece: Hand-patinated cast bronze leaves and 24kt gold over bronze acorn caps. Each acorn is created from hand-cast glass in shades of autumn leaf orange. The necklace is adjustable between 16 and 18 inches. This was likely purchased at Robertson Jewelers in New Milford, CT. This exact piece appears to be retired.
