We worked closely with Sandra to design a band for my engagement ring and she has been the very best!! My ring was set in a tiny gold band that wasn’t the best for the diamond. She created a band with a quilted interior so it won’t rotate as much and it’s the perfect mix of being elegant while still being a small gold band. Sandra made sure this would align with my wedding band. She did an amazing job with the cad and adjusting as we went along. We will come back to her for all our needs going forward!! Best jewelry shop for high end jewelry in Portland!!
Sandra Vonada is fabulous to work with. She is very knowledgeable and has great creative ideas to help you find the perfect piece of jewelry. Great communication and follow up. Highly recommend her!
We had such a wonderful experience designing our engagement ring! From start to finish, Jared was incredibly helpful, patient, knowledgeable, and personable. He took the time to truly understand our vision and brought it to life in a way that exceeded all expectations. Every step felt personal and special, never rushed or pressured to make a decision. We ended up going with a custom ring from A.Jaffe and it is absolutely perfect. We can’t thank Jared enough for making this such a memorable experience. Highly recommend to anyone looking for a jeweler who genuinely cares about their clients and the craft.
I went to Kassab Jewelers in downtown Portland for my fiancé’s engagement ring. Kassab had cuts of diamonds that I hadn’t found while researching other jewelers. From the beginning the experience was wonderful. Sandra was so helpful, she showed me a couple different cuts of the diamond style I liked, then through her expertise she helped me find the perfect setting for the diamond I chose. She was very communicative and kind throughout the entire process, and apart from her creative direction still made me feel that what I was buying was fairly priced, authentic, and one of a kind. I’ll be going to Kassab’s for all my diamond and jewelry needs. It’s been a Portland staple since 1975, and after my experience I can see why.
I came into Kassab because I had an unfortunate and stressful situation with my wedding ring where I was having to do an insurance claim to replace it and I wasn't having a good experience in dealing with the replacement/remake with the previous jeweler that initially made my wedding rings. Immediately when I went into Kassab I was greeted by Robert and made to feel right at home. He was so knowledgeable, extremely helpful and really took the time to show me everything I wanted to see and even other things he thought I may like. I felt like he really cared and wanted to really help in trying to turn my experience around and show me that I could have a great experience with them. After leaving the store and my time with Robert I decided that Kassab Jewelers was who I wanted to work with. From there Robert put me in touch with Penny because she is the one that handles the insurance claims. I went in and met with her and just like Robert, she was amazing and made me feel so comfortable and like she really truly cared about me. She was so empathetic to my situation and really made sure to explain everything in detail on how the process would work and what to expect. She told me she would fight for me and do the best she absolutely could in dealing with my claim. Throughout the whole process she was in communication with me, constantly giving me updates and working tirelessly to get me everything she could. Once we got the claim quote submitted to the insurance company, then came the fun part of redesigning a whole new ring as mine had been a total loss. Penny brought me in multiple loose diamond options to choose from varying in size, color, clarity, natural diamonds, lab diamonds, etc. She completely educated me on everything as we went, always making sure I fully understood everything. I feel like I learned so much about diamonds and really understood what I was buying, which was not even close to the case with my previous jeweler, they showed me 1 diamond and no other options were ever offered, where as Penny had multiple diamonds shipped in so I could see them in person, learn about each one and make the best decision for me. She was truly a blessing to work with and went above and beyond for me, she is a huge asset to Kassab, as is Robert and I am so thankful to have met them and to have gotten the chance to work with them. They made this stressful situation easy and fun and Penny delivered on her promise to do her best and fight for me, to get me the best she could, and boy did she deliver. I ended up getting a Tacori RoyalT Ring, which I could have only imagined in a dream, it's stunning and they were even able to have Tacori rush it so I could get it in time for a trip I was taking. I am forever grateful to these 2 people for all their help and hard work in this long process! Thanks to them I will be a lifelong Kassab customer.
