buying wedding rings in taichung

does anyone know a good place in taichung where to buy (solid) wedding rings for a reasonable price? let’s say for a price tag between 20-40k NTD. i know it’s cheap of me but i really wouldn’t want to spend any more on something that has only symbolic use for us.

don’t walk into local jeweler shops unless you know them really well and are buying pure gold jewelry.
just go to a department store near you.
Sophia booth has diamond rings at reasonable price.
