I have done business with Peter and Florence Chen at Opus Jewelers for over 20 years. I bought my engagement ring from them, so did my sister, my best friend, her aunt, three work friends and so on. Opus has also made me some fabulous custom jewelry based on favorite costume pieces that I loved but also wanted to change a bit. I have bought diamonds, pearls and all sorts of colored gemstones from them. All my jewelry appraised very well at my local jeweler and I get compliments all the time.
Pros: honest, knowledgable, fair, reasonable
