The opal astrolabe

THE PROMPT

A small brass desktop astrolabe with three translucent opal disks stands on a pale yellow stone surface. Tiny cloud patterns seem suspended inside the glass. A few fine engraved mechanical lines catch the light without forming readable text. Elegant close product photograph, shallow focus, believable refraction and restrained surreal detail. No necklace or pendant. Visual medium: High-end photographic realism, believable tactile materials, natural lens perspective, controlled depth of field and subtle fine grain. Keep texture clear without waxy smoothing. Palette: antique brass, honey cream, misty blue. Lighting: gentle macro product lighting with warm background glow. All human or humanlike figures are clearly adult and fully clothed. Original character and object designs. One coherent finished image, with no added lettering, logos, signatures or watermarks.
