How many styles for the vintage jewelry?

Vintage jewelry spans decades, each with distinct designs. Research key periods:  

- **Art Deco (1920s–30s)**: Geometric patterns, platinum, and gemstones like onyx or emeralds.  

- **Retro (1940s–50s)**: Bold, chunky gold pieces with floral motifs and cabochon stones.  

- **Mid-Century Modern (1960s–70s)**: Organic shapes, turquoise, and mixed metals.  

Choose an era that aligns with your wardrobe—e.g., Art Deco suits minimalist tastes, while Retro styles complement dramatic outfits.
