A biblical scene inspired by Revelation 21:21 showcasing twelve majestic gates. Each gate is a marvel of nature, crafted from a single, iridescent pearl glistening in the ethereal light. The gates are arranged in a semi-circle formation, each one distinctly different yet equally magnificent. The style, though anachronistic to the original text's times, would be similar to digital art with its smooth gradients, sharp contrasts and surreal color palettes. Also, do not incorporate any text or words in the image.
