Create a detailed image of a gothic-themed wedding ring designed for her. The ring features a dark, elegant design, crafted from blackened or oxidized metal, such as black gold or titanium. The centerpiece of the ring is a deep, dark gemstone, like a black diamond, onyx, or dark amethyst, set in a delicate, ornate band. The band is intricately designed with gothic motifs, such as swirling vines, thorny details, or tiny skulls, adding an edgy, yet refined touch. Surrounding the main gemstone, smaller, blood-red rubies or dark sapphires are set into the band, providing a striking contrast. The overall design is both elegant and bold, combining elements of gothic romance and emo style to create a unique and beautiful wedding ring.
