Maurice is running a top notch ship at Castle! Diamond Castle oozes elegance and grace. The staff is extremely professional and helpful. The jewelry is exquisite. Not only did they do our wedding bands but they brought a family heirloom back to life. My mother wore my late grandmother's engagement ring to our wedding in her memory and I have never seen this ring look more beautiful. They did an amazing job fixing it! Can't thank you all enough!

Built on a solid foundation of hard work, integrity, and strong principles, Diamond Castle was established in Woodbridge, NJ, in 1989. From the beginning, we knew that continuing and expanding our education within the jewelry industry would prove to be an important element of our success.

Our instincts were correct and by the early '90s, Diamond Castle had nearly doubled in size. We further enhanced our business by putting together a sales team with outstanding qualifications and a dedication to exceptional customer service that matched our own.

Diamond Castle specializes in engagement rings and wedding bands. We have the largest selection of engagement rings and wedding bands in stock every day: more than 3,000 designs! Redesigned and custom-made items are also a tremendous part of our business. Beginning with nothing more than a client's wish, we can create a one-of-a-kind piece that fulfills the client's every desire, down to the smallest detail. The fact that creating special designs became commonplace at Diamond Castle enabled us to add the tag line, Where Dreams Come True, and mean it.

Diamond Castle has acquired the working knowledge of both a superior retail jeweler and a manufacturer. This unique combination, along with the continuing education that we provide for our sales team as well as ourselves, truly sets Diamond Castle apart from the rest.

Today, Diamond Castle is located on the first floor of our new, elegant building at 355 US Highway 9 in Manalapan. The ambiance is elegant and chic, and our clients enjoy a relaxed shopping atmosphere among beautiful jewelry.

My fiancée and I ran into some trouble with our first engagement ring from another place. Unfortunately it had to be returned. I was given this recommendation by a friend of mine who get her rings here. It was far for us, but we gave it a shot. Nick helped us for an hour right before closing on a Sunday and was totally patient and helpful while I looked at different settings and different cuts of diamonds. He also worked with our budget. I came back a second time, as Nick ordered some diamonds that would fit my budget but still look nice. In the end, I got the setting that I absolutely love with a diamond that is just amazing---at a price that didn't break the bank too terribly! They were able to size it for me and set the diamond on my second trip back and I left with a beautiful engagement ring that I just can't stop staring at. In love. I do recommend this place and Nick for great service. I will be returning for our wedding bands.

Although my proposal was a surprise, I always knew I wanted to pick out my engagement ring - I'm the one who has to wear it, right? When we were ring shopping, I thought I knew exactly what style I wanted, but for some reason I didn't fall in love with any of the rings I was trying on! When we went to Diamond Castle, the woman we were working with decided to give me some out of the box rings to try on, and voila, I found my beloved engagement ring! It looks NOTHING like what I had originally wanted! I love how unique it is :) They worked with us to stay within budget when choosing the center diamond. We also ended up buying our wedding bands there - since we purchased the engagement ring with them, they gave us a great discount on the bands and helped us choose the perfect ones for us! I also purchased my wedding jewelry (matching bracelet/necklace/earrings set) from them - it's CZ but looked like sparkling beautiful diamonds on my wedding day!

I cannot say enough good things about Diamond Castle! When my fiance went to pick out my ring he said they went above and beyond to be sure he found the perfect one! The ring is sturdy and shines brighter than ever! I'm pretty rough with my hands and the ring last beautifully. The store is gorgeous and the service to have your jewelry cleaned is quick & convenient . I'd reccomend this store to anyone searching for an engagement ring or even just jewelry.
