A gothic Valentine's Day-themed frame with intricate and dark designs. The frame is decorated with deep red roses, dark skulls, purple and black crystals, and silver accents. The edges of the frame feature jagged crystal formations, ornate lace details, and delicate vines. There are elements like dark candles, and a haunting, mysterious ambiance surrounds the frame. The center should remain empty, creating a dark romantic mood, with a focus on rich tones of purple, black, silver, and dark red. The overall style should evoke a gothic Valentine's theme."
