Ornate Art Nouveau frame with gold, turquoise, and green organic patterns surrounding a beige marble-like center.

A perfectly symmetrical Art Nouveau decorative frame designed for a board game, square-shaped inside and outside. The inner area is left completely empty (transparent or blank), perfectly centered, with proportions matching a game board. The frame itself is elegant, finely detailed, and in the same visual harmony as a bright marble-and-glass winter garden in the Belle Époque style — inspired by Alphonse Mucha and Louis Majorelle. The materials evoke polished beige marble, turquoise and gold mosaic inlays, and delicate stained-glass accents with organic vine-like Art Nouveau shapes. The frame should be subtle yet ornate, not too thick, leaving generous inner space, and must allow for safe print bleed margins. Add a faint sense of natural daylight warmth to match the “morning light” palette of the previous image. The overall composition is perfectly square, crisp, and highly detailed, with a refined, painterly style suitable for luxury game design. See more
