Enchanting Harry Potter Inspired Shield Emblem

Create a shield emblem in the rich colors of the Harry Potter universe, incorporating deep burgundy, gold, and emerald green. In the center of the shield, place a beautifully designed round long glass vial pendant with a green leaf inside it, and it should hang from a fine chain. The background should be subtly textured to give an antique feel, reminiscent of magical artifacts. Include soft, ethereal lighting that highlights the pendant and adds a mystical glow to the entire composition
