Gold-tone pendant necklace with ruby charm

I lost my gold-tone pendant necklace yesterday around 3pm near the Queen Victoria Market entrance on Elizabeth Street. It's a small 2 cm oval pendant on a 20 cm delicate chain, with a tiny ruby dot in the corner. The back has the initials 'A.J.' engraved. The necklace shows a bit of wear—hairline scratches on the pendant and the clasp is a little stubborn—it's been through a lot with me. It means a lot because it was a gift from my mum and I wore it every day. If anyone finds it, please message me here or email me at [email protected]; I’d be so grateful to have it back.
