Lost Gold Sapphire Ring outside Parkgate Hall, Dublin 8

I temporarily took off my gold and sapphire ring when I was outside Parkgate Hall, Conyngham Road, Dublin 8, and it must've fallen out of my pocket! The ring is a simple gold band with a sapphire center. After Conyngham Road, I cycled into town, may have fallen out of my pocket then? The ring is really really important to me and has so much sentimental value. If anyone has seen it please let me know!!!
