Extremely happy customer at Costello Jewelry Co. The customer service provided from Ralph was 5 stars from start to finish. Very impressed with the work done and skill to transform my antique ring into the pendant I envisioned. He listened to my concerns and vision for the custom job and ... worked with my budget and time frame. I even was educated on mixing gold etc… and how to ensure long lasting pieces. The knowledge each member of the team provide is exceptional. This was the third time I used Costello Jewelry Co - I had a shank redone on a ring, a ring re size, and this beautiful custom ring to pendant. I will definitely be back! Bonus: Complimentary jewelry cleaning every time you're in store! The best. Thank you Ralph and Costello Jewelry Co! Read More
Such a fantastic experience at Costello Jewelry! Leslie helped me to order links for my watch which was impossible to find. So friendly and very helpful, thanks again! Read More
Love this jewelry store. The staff is friendly and everybody went above and beyond to help me. I ended up with something nicer than I could've had from a bigger jewelry store and still came in under my budget. The owner is great. I don't have a reason to use ... any other jewelry store. Read More
Super cool and friendly staff here. I had some jewelry cleaned at no charge when I visited. The overall environment is very friendly and welcoming. The jewelry selection is great as well. I recommend Costello Jewelry Company to anyone who's looking for cleaning/repair work or a new piece of jewelry.
Ralph and his crew repaired my broken pendant in just a few days (sooner than expected) for a great price. Also has great pieces of jewelry in the store as well.
The people are helpful, supportive, and efficient! We've been using their services for years, now, and are always satisfied with their work and their quick turn around! We sure appreciate their assistance!
I just popped in to Costello the other day to fix a clasp on a bracelet that had weakened, and not only did they treat me like family, they tightened the clasp for free and cleaned my other two rings. I've been a customer of theirs for about 20 years ... and I will continue to support them; they're awesome! Read More
