Visited this store which is on the second floor of the Millender Center recently for some watch repairs and I was extremely pleased by the level of courtesy and professionalism. They've been in business for many decades and it shows. I appreciated time they took to explain to me unique features of the time pieces I brought it and to answer my various questions. Places with deep knowledge and skill of Costa D'Oro are rare these days and I'm very happy to have a place like this in downtown Detroit. Prices are also more than reasonable. Highly, highly recommended.
Costa was efficient and very friendly. Not only did he fix my watch quickly, something the brand name store couldn’t do, he gave us a ton of options for places to see while we were in town
Several years ago, I had to have my wedding ring and engagement ring cut off due to emergency surgery. Also, I wanted my husband's wedding ring resized to fit me. In total, I had six rings either resized, repaired and/or cleaned. I am absolutely thrilled with the results. My daughter remarked that they all look like new rings which is amazing considering their age. Thank you so much to Costa D'Oro jewelry for doing such a remarkable job. I will be using your services again.
My husband had been referred to Costa to purchase a ring for me for Valentine’s Day gift from a couple of friends. When I received the ring I was absolutely blow away! My ring is so stunning and gorgeous! I have never seen any ring like this before and it screamed my name! My husband and daughter did a great job picking this out. Everyday I still wake up in stunning like this is mine. Today I had the chance to go downtown and meet the great jeweler in person, I had to have the ring perfectly fitted. He was very professional and polite, I now understand why he was so highly recommended. I will continue to recommend him to anyone in or out of the Metro Detroit area! Thank you.
I’ve been a customer since 1998 & I have never been unhappy with any repairs or purchases. Excellent selection of jewelry & if he doesn’t have what you’re looking for, he’ll make it for you. His customer service is above & beyond. I will always be a loyal customer.
