Symmetrical Art Nouveau decorative frame with polished beige marble, turquoise, and gold mosaic inlays, featuring organic vine-like patterns.

A perfectly symmetrical, ultra-thin Art Nouveau decorative frame designed for a luxury board game. The frame is square both inside and outside, with the inner area completely blank and centered — large enough to contain an illustration later. The decorative border must be very thin and delicate, occupying only a small margin of the image (around 5 to 8 percent of the total width), so that the inner space remains wide and open. The frame design should harmonize perfectly with a bright Art Nouveau winter garden from the Belle Époque era, featuring polished beige marble textures, turquoise and gold mosaic inlays, and subtle stained-glass motifs with organic, vine-like patterns inspired by Alphonse Mucha. The overall mood is luminous, elegant, and morning-like, as if bathed in soft daylight at dawn. The artistic style should be refined, balanced, and richly detailed yet visually light, with fine ornamental lines rather than heavy ornamentation. The image must be perfectly square, crisp, symmetrical, and suitable for print bleed margins. Emphasize the ultra-thin nature of the frame — it should look subtle, airy, and graceful, not thick or heavy. See more
