LOVE THESE PEOPLE!! So helpful and accommodating!! Best custom jewelry experience I’ve ever had!! I had a situation where my custom ring wasn’t quite what I envisioned; (even tho rare carat did exactly what I wanted), they helped me achieve my dream!! Gave me full credit toward the changes I wanted, AFTER I had the ring I requested and had custom made..I’m blown away by all of the people I’ve interacted with..Emily, Shelby, and Sunny!! They are the most responsive people, and I tend to be on the obsessive side, so the fact that they responded to me so quickly means the world to me!!!

⭐️⭐️⭐️⭐️⭐️ Exceptional Company — Rare Carat Sets the Standard! I am absolutely thrilled with my experience with Rare Carat. From start to finish, their team went above and beyond to help me create the perfect gift for my fiancée. Their quality, honesty, and communication were second to none. What impressed me most was their genuine care and willingness to go the extra mile — even the CEO personally made himself available, which speaks volumes about the company’s commitment to its customers. The entire process was seamless, transparent, and handled with such professionalism that it completely exceeded my expectations. Rare Carat truly stands head and shoulders above all others in both craftsmanship and customer service. I couldn’t be happier with the result and wholeheartedly recommend them to anyone looking for an exceptional jewelry experience.

Working with Michael at Rare Carat was such a wonderful experience. From the very beginning he was so kind, patient, and honest. He didn’t just try to sell me something or write me off when I had concerns about my ring — he took the time to educate me on the best specs for my ring setting and made sure I understood every detail. I could tell he genuinely cared about helping me find the perfect fit, and he went above and beyond to make the process smooth and stress-free. I’m so grateful for his guidance and support — thank you, Michael, for making this such a special and memorable experience!

I had the absolute pleasure of working with Michael at Rare Carat on my engagement ring search, and the experience was outstanding. From the start, Michael stood out with his professionalism, deep gemological knowledge, and his ability to really listen to what I wanted. He helped me compare my top diamond choices with incredible attention to detail, pointing out subtle differences in cut, symmetry, and bow-tie effect that I wouldn’t have caught on my own. What impressed me most was the effort he put into making sure I didn’t just find a great diamond, but the right one. He walked me through every step of the design process, gave me clear options for customizing the setting, and went to great lengths to help me secure the best possible price for the diamond I wanted. At no point did I feel pressured — instead, I felt supported and well-informed. Michael made a process that could have been stressful feel smooth and exciting. I came in with a high bar for service, and he exceeded every expectation. If you’re looking for someone who genuinely cares about making sure you end up with the perfect diamond and setting, Rare Carat — and Michael in particular — is the place to go. This was a 5-star experience all the way. — Zach
