Erik did an amazing job with my engagement ring! He let us know black gold can be a bit tricky but it looks flawless. Really nice and easy to talk to! Will definitely go back for future jewelry needs.

Went in looking for a small jewelry box to hold a ring for my young daughter. After several other stores told me they would not give me one or sell me one without the purchase of jewelry, DeRosa give me three of them for free. Thank you.

Came across their Maps page when I was looking to have a ring sized down and a ring repaired. Both repairs were done in a couple days and for way, way less than I expected. They were fun to talk to and helped me figure out what size I needed to go down to. I'll recommend them to anyone I know looking for repairs or custom work.

Professional, knowledgeable and all around excellent quality at DeRosa Jewelers. Purchased this beautiful Diamond in a Rose Gold setting. Erik fixed the setting to make it the perfect size for me. I absolutely LOVE the ring. I will definitely be back for more!

This is THE place to have your jewelry repaired. It was the quickest and easiest experience. My engagement ring is thin, and I bent it during a move. It was missing a side diamond and had a crack in it. I did not want to have a repair done somewhere they shipped my ring off. Eric was polite and professional, he fixed my ring right in front of me within 10 mins.

I would highly recommend this repair location. They do repairs on site and they were able to do mine the same day. This business sets the standard when it comes to customer service. Go here, you won't be disappointed! They also have a nice selection of bridal rings and vintage/estate jewelry for unique gifts.

I trust Erik for all of my jewelry needs. Albeit for jewelry repairs or if you want something custom made, or off the shelf, etc. He is a true artist and very honest. He makes sure you get the best quality and value for an affordable price. I have also referred friends of mine to Erik and they were also thrilled with their customer experience! I Highly Recommend going to see Erik if you're evaluating options.

DeRosa helped me right away to repair the sizing job that another jeweler botched. I was able to bring a properly repaired ring home within an hour and for a low fee. I will be bringing all repairs here from now on. Thank you so much for your help!

I used a saw to remove this focal piece out from a cuff bracelet and made the chain for it to turn it into a necklace. Unfortunately I had no way to solder the jump rings to attach the chain as a torch would damage the focal piece. Erik was able to laser solder the jump rings to attach the chain. He did it well, fast and for a reasonable price. He was also very personable and knowledgeable. I will definitely be back.

Carl is amazing! I brought my engagement ring that my fiance had made by Carl in for repair and sizing.(I should have brought it in to be sized months ago hence the need for repair) he quoted me a fair price and said he could have it ready in a few days. Got a call same day with fantastic news ring was almost ready and I would be able to pick it up that night before closing! I can't say enough good about this jeweler he does amazing work he is a true artist! Thank you Carl!

Carl is the amazing at what he does. I had my engagement ring, wedding band for her and a wedding band for myself designed and made here. Using the gemstones I wanted, Carl worked with my budget. He explained everything, educated me in the subject matters of gemstones and metals. Showed us the final CAD-design on how it'll look on his big TV. He just made it so much more personal and came out on top with the final products.

Best thing I ever did going there unlike all of these big chain jewelry stores where the sales person just wants to make a sale, Carl will take his time and make sure understands you and you will leave happy with your purchase and no buyers remorse later either. He is the best!

If you are searching for a jeweler in New England, look no further than DeRosa Jewelry. Carl is welcoming, professional and an excellent communicator. I recently worked with Carl to design the most spectacular custom engagement ring for my fiance. Carl patiently guided me through all the steps, answered all of my questions promptly and even finished the ring a week ahead of schedule! I couldn't be happier with the end product and my fiance loves her custom engagement ring. I look forward to working with Carl for all of my future jewelry needs.

I went here to get a watch engraved for my significant other. Carl was fast, efficient and helpful. I got the product back quickly and it came out perfect. Carl was also knowledgeable and informative throughout the process. The service and price here was perfect.

I brought a ring that had a lot of sentimental value and needed to sized up and cleaned. He did a wonderful job and did it very quickly. Also brought in a ring that needed a stone replaced he was great about really looking the ring over and making recommendations for how to make the ring look the best. Another stone was really scratched and needed to be replaced so it would look as good as the new stone. He took the time to look over what I needed done and ensured it was done with the highest quality and workmanship. Highly recommend.

I'm new to the area, and I googled pawn shops near me because I had some jewelry to part with that I hadn't worn since middle school. Carl was fair and examined each piece and explained each step of his process. He has a flat-screen that he uses as an extra monitor and pulls up daily trade rate of gold etc. and shares his excel calculator as well.

I got double what I expected for my items without having to haggle. I was pleasantly surprised by the experience. Carl also has an impressive catalog of custom jewelry that he has designed. Have you seen the octopus tattoo that he converted into a pendant? Check out his Instagram and Facebook @DeRosaJewelersUSA to view his bold and beautiful creations for men and women. Also, I hear he's looking for a couple of commission-based sales reps to send him leads for repairs and designs, contact him for info on that!

My experience was not I was expecting at a business showing up as the nearest pawn shop, and I was pleasantly surprised to meet Carl, a Portuguese born artist with a unique eye for detail who is like a renaissance sculptor with gems and jewels.

Carl is attentive and generous, and his work is stunning! He made my ring exactly to my specifications! I'm excited to work with him again for my wedding bands!
