Our Patronus necklace features a carved Agate Cameo framed in fine precious metal. We chose the cameo to represent the Patronus for the beauty and mythology behind it; the first cameos originated in ancient times, by talismans whereupon magical spells were carved. Our original agate cameos are masterfully crafted in Germany by some of the best gem carvers in the world.  The pendant measures about 31.3mm long (excluding the bale) and about 16.2mm long. Our metal options are sterling silver and solid gold. We advise selecting the same precious metal for both pendant and chain. All of our metals are nickel-free, and we use recycled metals whenever possible. All of our pieces are handcrafted by expert fine jewelers in our Seattle workshop.
