A majestic, hyperrealistic queen chess piece, adorned with glittering diamonds and sapphires. The piece is a golden, ornate figure, crowned with a lavish diamond tiara, and a flowing, diamond-studded gown. The queen's hair is a cascade of intricate, diamond-encrusted strands. A full chessboard, with other similarly elaborate, gemstone-studded chess pieces, surrounds the queen. The scene is set against a night sky backdrop with a full moon. Dark blues, purples, and deep blacks are blended with the golden hues of the chess pieces. A sense of richness and opulence is key. Lighting highlights the intricate details of the gemstones and the figures. Emphasis on hyperrealism, detail, and the interplay of light and shadow on the gemstones.
