Quartz Tide

Create an original 4:5 vertical surreal seascape titled Quartz Tide. Several enormous clear quartz cuboids hover a few meters above a shallow calm ocean at dawn, casting refracted rainbow shafts into the water. Low horizon, pale peach sky, precise crystal inclusions, tranquil monumental scale. No land, boats, people, text, logos, or watermark. Photorealistic fine-art image.
