I would not trust your watch to get serviced properly …read more.. I did give these guys a shot last year replacing the band. While it took days if not weeks longer than expected, I had no reason to fault them specifically. This time, I needed a new battery. According to Tissot, the time difference and hand lag (pictured) is due to improper battery changing sequence and/or incorrect battery. When I called to let Castello know, and find out next steps, the manager Michelle was fairly rude and defensive instead of helpful and understanding. She said things like: "we change 20 batteries a day" "I have worked here for 30 years" "I have sold 100 of these watches" "We have sold Tissot for 40 years" and sooooo many other things like this instead of "let me find out about that" or "I will take care of that for you". She did come close with "we will send it to Tissot for you and report back with how much the repair will be" ....yikes. I said I was ok paying for anything not related to their apparent lack of experience changing batteries in a T-Touch, but there was no offer to stand behind their work, as I read the wrong battery can "fry" the watch, whatever that means. One last Michelle quote:(she does love to argue and be defensive) her: "Is the watch working" me: "yes" her:" that means the battery is good" LMAO I even did a little homework, emailed it to her, and asked if the battery brand used or sequence was followed. She thought the idea was absurd that she read that email from me, when all I wanted was to find out how or if they could help rectify the situation. I visited today to get my $25 back, and decided just to send to Tissot for repairs myself. A LOT more words from Michelle, most of which contradicting her statements form our phone call like "I said I would take care of it" "we have sold Tissot for 35 years" "I have worked here 31 years" etc. but no $25. They are out here just stealing money at this point lol. I will see what Tissot comes back with and if the battery was the cause of any damage, I will return for Costello for them to reimburse and hope they come to their senses and do the right thing. Stay tuned for my updated review!!

This is the first time I had an original ring designed, though. I worked with Marino Costello on the design process. As an anniversary gift, my husband wanted to buy me a ring, but I decided that I couldn't give up my original engagement ring and wedding band so I had a new ring designed utilizing the diamonds. The process was interesting. I looked at rings in the jewelry store to get an idea of what I wanted and then we proceeded to the design process, Marino sending me CAD drawings and then a wax ring was made where I tried it on to get an idea of the design and dimensions. My new ring is gorgeous! Marino is a fabulous designer and so easy to work with. I appreciated his attention to detail and his quick responses to my emails. The design process was fun. I love that Marino designed such a special ring where I still have the original diamonds that my husband gave me 20 years ago. I highly recommend Costello Jewelry!

I went on Thursday because that is when the specialist (Collin I think was his name) was there who could evaluate the ring and offer me a price. He said hello and asked if I had an idea of what I wanted. I didn't want to give any information to him because I wanted to see what he said. The man took my ring, disappeared in the back for five minutes, came back out and said diamonds had gone down in value and he could only offer me $50, but would give me $150 for the gold rings. I said thank you and left, suspecting the ring was worth more. I then went to Marry Me Jewelers in Countryside. Gino Senior invited me to sit down, educated me on the 4 C's, involving me in the evaluation process and then offered me a very fair price (several hundreds higher!) for the diamond ring. I will never go back to Cottage Hill simply because I felt so dismissed and disrespected. I have shopped there before and loved the other employees/jewelry (including a beautiful amethyst necklace they designed for me) -but this condescending employee has changed my mind about Cottage Hill forever. How disappointing! Do better.

Quotes in hand, and both good things and bad things to say about each, we were starting to believe a jeweler who combined great pricing, great service, and an eye for detail simply couldn't exist. Joe came through on all fronts: he was less for the diamond, faster on the turnaround, and small enough to share his cell phone for personal updates when needed. Every step of the way, from design to manufacture, we were comfortable and informed, even when the mandatory element of a surprise proposal kicked in. This was all because Joe was professional and transparent, and we're grateful for our investment in him.

Then, my girlfriend had a small bag of some old jewelry items, Joe took a few minutes to look at each piece, tell us what kind of gold it was and how much we might be able to get if we sold it at one of those cash for gold type places, as well as look over her old diamonds to tell us about those as well. He even showed us websites so that we can see the going rate for the types of diamonds we had in these misc. rings and necklaces. It made our lives a lot easier when we did sell the items because we had a really good idea now of what we actually had and what we would probably get if we sold the items. Now my girlfriend wants to get a necklace from Joe, I better get a 2nd job.........Greg
