It appears there's been a misunderstanding. The image you've provided is of a belt buckle with a skull and piston design, not a handcrafted men's ring or signet ring for the German market. However, I can still create a product description for the item shown in the image in French, if you would like. Please let me know if you would like to proceed with this item or if you meant to provide an image of a ring for a description in your requested format.
