I wouldn't take their appraisal as 1st choice. Definitely get appraisals from several places, and also research the piece you're trying to appraise

Found Unique Gold and Diamonds through a Google search. Was looking for a Jewelry Store that was open on a Sunday, to replace a watch battery. Mike the owner, was excellent! Replaced the battery in about 10 minutes, and the price was very fair. Liked that I didn't have to travel to a shopping mall either, to get this done! Shop local and support our local small businesses. See Mike and he'll take care of you. Highly recommend!

My fiancé and I feel beyond lucky to have found Unique Gold & Diamonds in Clifton, NJ in our search for the perfect engagement ring. Michael, the founder, spent time with us over a series of three appointments, during which he listened to our needs, provided his expert advice, and answered our many questions. He was always attentive, personable, kind, professional, and never rushed us. He conducted himself with integrity, never attempting to upsell us or sway our decision. He provided us with a great price for a custom-made ring, for which he sourced the raw materials (diamond, metals) and machined himself. After we finalized the design, the turnaround was super quick — the ring was ready in just under a week. Overall, our experience was top notch, 10/10. And of course, the final product could not be more perfect. We will always be grateful and remember Michael and Unique Gold & Diamonds as part of our story.

Couldn't have imagined a more perfect ring to propose to my fiancee and Mike worked with me every step of the way to make sure not only that I was educated about my options but also never felt like I was being upsold, literally creating a ring that always gets complimented and was just what my fiancee imagined. So when it came time to get our wedding bands, there was no other choice but to have Mike work his magic again. Happy to say that we've found our jeweler for life

My fiancé worked with Unique Gold and Diamond to custom design my engagement ring, and it turned out absolutely perfect! Mike and Mike (the owners) were fantastic, guiding him through the process, and Fazal was the most amazing—so knowledgeable and helpful every step of the way. They even offer complimentary cleanings, which is such a great perk to keep the ring looking its best. I highly recommend Unique Gold and Diamond for exceptional service and stunning jewelry!

Very professional, fairly priced, and great service. The people over at unique gold and diamonds made my custom engagement ring just as I wanted, with my own jewels. I'm definitely coming back!

Recently made this pendent! They had a huge collection of loose stones to pick from and I found this electric green peridot. Mike helped me choose a setting from many styles and then his jeweler set it in this 14K setting. Also, A gold chain is a bit out of budget right now so he suggested we do a plated gold silver chain. We haven’t gotten it yet but hopefully I can update once I get the new chain 🙏 Beautiful work and experience. Will be coming back to make more in the future 💚
