Thorns is a solid sterling cast -castings are not hollow, they are a solid piece of metal like a bullion with artistic shapes- that has been sanded to perfection to prevent the tips to hurt the wearer. 
It could be perfectly be worn as is on a chain or be a focal element for a bolder piece with leather cords, beads, sterling accents or even textiles. 
A cool gift for a wild "other half" and heavy metal brutalist, industrial style and modernist lovers with a masculine edge with no stones.
