Envisage Revelation 21:21 with its grand description - 'The twelve gates were twelve pearls, each gate made of a single pearl.' The entire visual representation to be in the form of a watercolor painting. A vividly described scene of celestial gates chiseled from luminous pearls, each one standing majestic and sublime. To add to the ethereal beauty, picture every gate as hewed from a single gargantuan pearl, resonating an otherworldly sheen. Render the pearl gates as imposingly large yet elegant in appearance, oozing a gentle luster that reverberates in the heavenly realm. The radiant light streaming through each gate paints illuminates this scene with its soothing hues.
