Description
A small monument to exploration.
This Astronaut Keychain is crafted from solid brass, shaped as a compact sculpture with a striking presence. At 45 mm tall and weighing around 50 grams, it feels substantial—an art object you can carry.
Each piece is meticulously hand-finished in Germany and offered in two distinct surfaces: a brilliant high polish that amplifies its reflective contours, or a soft matte finish for understated sophistication.
More than a functional accessory, it is a daily companion with character and gravity—
a distinguished statement for the everyday, artful, expressive, unmistakably Oney Koontz.
Material
925 Recycled Sterling Silver
Our jewelry is crafted from 925 recycled sterling silver—a premium alloy composed of 92.5% pure silver. The remaining 7.5% copper enhances durability while preserving silver’s distinctive, luminous character.
By working exclusively with recycled silver, we conserve natural resources and reduce environmental impact—creating jewelry that embodies conscious luxury, without compromise.
18k Gold Vermeil
For our gold-finished pieces, we use only 18k gold vermeil, a superior and enduring gilding technique. A generous layer of genuine 18-karat gold—with a thickness of at least 2.5 microns—is bonded to a sterling silver base.
Unlike conventional gold plating, gold vermeil offers exceptional depth of color, enhanced longevity, and is entirely free from base metals such as brass or nickel. The result is jewelry with a warm, lasting gold glow—refined, resilient, and perfectly suited for sensitive skin.
