Met with Zack today to sell my bridal set from my last marriage and Zack was really nice and showed a lot of knowledge for diamonds. He had a lot of insights and communicated with me what he was doing to my rings so I knew what he was doing for every step of the process. He gave me a really fair offer. I really appreciated his communication! Thank you again Zack :) read more

Kal Diamonds is as good as it gets. My wife's engagement ring recently snapped (on her bday mind you) as she was pulling an outfit out of the closet for the night. I brought the ring to Kal Diamonds. They assessed the issue as I was sitting there, out it in a bag, and told me they'd text me in a couple days - which they did. The ring was returned in better than new condition, the cost was fair, and the service was simply outstanding. I'll be doing business here again soon, and will continue to inform friends, family, and anyone else I know to speak with Kal diamonds for jewelry related needs read more

Kal Diamonds is the place to go if you are looking to sell any of your diamonds or gold. Zack is extremely knowledgeable professional courteous and very very patient. And the most important aspect is that he is trustworthy and that's saying a whole lot for somebody in the jewelry business. Best customer service in Phoenix! read more

I have been trying to sale my diamond ring set for several months and while I know covid put a major stressor on may things I was really struggling to get what I wanted for it. I went to see Zach and instantly felt comfortable. After speaking with him for some time I realized that he had my best interest in mind and really cared. He is so awesome and I hope to be able to do business with him in the future. I couldn't imagine selling my rings to anyone else. I am so happy I found him. If you're trying to sale your jewelry you can stop looking cuz you'll love doing business with Zach. read more

We had a a 1.5 Princess solitaire set in platinum we wanted to sell. We received offers from online buyers and several large Scottsdale buyers, many of which were insulting. We were about to give up when we decided to try one last buyer and happened upon Kal Diamonds. What a wonderful surprise! Zack was extremely helpful in explaining the buying process and what estimates are based on. Kal surpassed all previous offers and provided us with the highest level of customer service! If you are looking to sell, contact Kal Diamonds first! You won't be sorry! Thank you, Zack! read more

All I have to say is I wouldn't take my business anywhere else. Zack is the greatest. He is honest full of information and very personable. So happy I found Kal Diamond. Will be heading back there again soon. Thanks Zack read more

I highly recommend Zack to anyone who needs to sell jewelry. I wanted to sell my ring after a recent seperation and really did not know what to expect. Zack surpassed any expectations I could have imagined. He is kind, patient and not pushy at all. He likes to hear your story and the "why" behind the sale. He educated me about the process and was transparent in his communication. I asked him to give me 24 hours to make sure I was making the correct decision for myself and he was completely supportive of my time line. I never felt rushed, or pressured to make a decision at any point. I highly recommend that you see him for your jewelry needs. read more

I had a 3.51 round brilliant SI1 F diamond to sell. I had worked for a jeweler years ago selling diamonds so I am very knowledgeable and knew what would be a reasonable price. Prior to finding Kal Diamonds I met with 2 large diamond buyers in Scottsdale and they gave me low ball offers. Then I found Kal Diamond and Zach was awesome. He is very knowledgeable and honest, he made me an offer I couldn't refuse. I liked working with him so much that I bought another stone from him. I highly recommend Kal Diamonds! read more

I would recommend Zack to anyone in a heartbeat. He was extremely professional on our phone call and in-person meeting. He took the time to hear my story, examine my diamond, and explain what estimates and selling prices are based on. I felt like he was honest, transparent and trustworthy. However, since it was my first time selling a diamond I wanted to get a few other offers. He was polite and let me do my due-diligence. Every other place I visited in Scottsdale was disappointing after meeting Zack (both in offers and salesmanship). Zack's customer service was unmatched! Not only was he knowledgeable and honest, but he offered me the best price. I highly recommend Kal Diamonds! He made a painful process a little more bearable. Thank you, Zack! read more

Zack was professional from our first phone conversation ..and upon meeting him, he took he time to carefully examine my stone, explain price points/values and even sought a second opinion. He is down to earth and made a somewhat difficult progress more bearable. I would highly recommend his services to anyone. Thank you Zack!!!! read more

We found this place on Yelp and went based on the review below. We had a very similar experience. Zack was very helpful, knowledgeable, and great to work with. I would highly recommend him! I would recommend making an appointment, Zack was nice enough to help us even though we didn't have one. read more

After multiple times of dealing with really sketchy people on Craigslist I decided to take my Rolex to Zack at Kal Diamonds. Immediately after walking into his office he made me feel at home offering to get me something to drink and asking if there was anything he could do to make my visit enjoyable. He was kind and knowledgeable when it came to answering questions about my Rolex and he understood that this wasn't just a piece of regular jewelry but an investment that I was sad to let go of. He showed me competitive prices from local jewelers in town and prices online. He beat them all! He definitely looked out for my best interests and made the experience very pleasant. I would recommend this guy to anyone looking to get rid of high end jewelry and or making a big purchase on new jewelry. He will spend as much time as it takes to make sure you get everything you want and need! Thank you Zack. read more
