Amazing people in this store. They were very polite and quick. I bent my wedding when I slammed my finger in a door and they were able to fix it very quickly as well as adjusting the size. It was much appreciated and I will definitely be back.

This Jewelry store is Amazing! I went to 4 other jewelry shops and it didn't even come close to the customer service here. I highly recommend this place over any others. The selection he has in his store is breathtaking. This is the best jewelry store I have ever bought anything from.

I received excellent service at this jeweler. My ring was resized perfectly from initial fitting/sizing to finished product. Mr. Biegert is a full service jeweler, and obviously very knowledgeable. He also did an inspection of an old watch of my husband's and when he was sure he could not repair it himself, offered us the contact details for someone who could. I was so pleased with the service and pricing here that I ended up buying some earrings that I will treasure forever. The store is easy to find, and parking is available very nearby (within a block).

I'm only giving this store 1 star because I have to. I went in today & wanted to see a ring. I'm recently engaged & getting married March 6th. The lady told me shr can't let me hold the ring. I said how can I buy it if I can't see it on my finger? Again, she said I can't let you hold the ring. I asked her does she let white people try on rings & she told me yes. UNBELIEVABLE!

She spoke truthfully & too soon. I could see all over her face that she knew she had messed up. As I walked to the door she then asked me my ring size. I told her 8 but don't worry about it. She then tried to tell me I could try it on but the damage was already done. I was so mad I was shaking. Mind you I'm a teacher & my fiance is a nurse, I had to 1 carat diamomd rings on at the time & have enough money to buy 5 of those rings if I so choose.

But being black I guess my money wasn't good enough for her. I was COMPLETELY disrespected & discriminated against solely based on the color of my skin that she even verbally admitted! I am completely amazed & infuriated. This place needs to be SHUT DOWN!

Awful customer service! I went into the store today to sell a ring and look for an engagement ring. When I approached the counter and told the man I would interested in selling my ring, he told me that my ring "wasn't right" and when I asked for more detail I also told him that I didn't have much knowledge about jewelry. Then he basically said that the ring I brought was fake, and when I said that I didn't think it was, he said He was just trying to educate me.

I will not be back to purchase an engagement ring and I hope he knows he lost a sale because of his rude attitude. Go somewhere where the customer service isn't rude and actually tries to care for their customers, and not somewhere makes you feel stupid for walking inside.
