    Armin is the absolute best and sweetest! He really listens to what you want and doesn't try to upsell you. If he thinks something won't work or look good, he'll tell you instead of just trying to make the sell or charge more. I'm obsessed with my ring- it's absolutely gorgeous!

    I want to give a huge thank you to Armin for helping me choose the perfect ring for my fiancée. There's truly no one like him. The pricing was phenomenal compared to what's out there, and beyond that, the experience was incredible. I spent a lot of time with Armin, going over ideas, photos, and videos. Instantly, he knew exactly what my fiancée would love. I told him I needed the ring within four weeks or less since this was a last-minute plan, and without hesitation, he assured me he could make it happen. Not only did he deliver on time, but he actually finished the ring earlier than expected, allowing me to take it with me on my trip to propose. The ring is absolutely stunning, and for the price I paid, I know I would have ended up with far lower quality anywhere else. After my trip, we had a little incident where my fiancée hit her ring extremely hard while traveling. As soon as I landed back home, Armin got me in the same day and fixed everything within an hour--just in time for her to show it off to all her friends! I truly appreciate all the hard work he put in to make this happen, and I'll be recommending him and his business to anyone in need of quality jewelry and a friend in this industry

    Custom diamond engagement ring

    Armin went above and beyond in helping us create a custom engagement ring. From helping educate us on 4Cs, platinum vs. gold, to even insurance coverage. He helped make our vision come to life and made the experience truly exceptional. We did a lot of research prior but knew we selected the best! Armin comes with decades of experience in the jewelry industry.. you can truly feel his passion and care for his craft. He took his time showing us the different options, always responsive and was kind to allow us to come back as much as we needed to. We instantly knew he was someone we could trust for the long run. When you're spending a significant amount on an engagement ring, it's more than a purchase, it's a long term relationship. We'll be back to purchase many other pieces, and this gorgeous ring will be passed down for generations. I can't recommend him and his company enough!

    Engagement ring made from my mother's marquise diamond and the teal sapphire and diamond ring I fell in love with.
    Varina B.

    amazing customer service experience. incredibly beautiful rings. I bought three rings. had an engagement ring made from my mother's marquise diamond in her wedding set. it is absolutely STUNNING. I also had a custom wedding band made that embedded four gems inside the gold band. Both rings were very reasonably priced. While I was working with the amazing Armin to create those, I fell in love with a teal sapphire and diamonds rings and bought that on the spot. I have NEVER done that nor have I ever spent that kind of money on jewelry for myself. it was that beautiful, it took my breath away! Could not recommend more.

    To say I am happy with my ring is an understatement! I am OBSESSED!! I lost my original wedding ring shortly after my 8th wedding anniversary I was devastated and looked at countless of stores only to be let down that nothing moved me the way my old one did. My husband and I met Armin and very quickly we clicked he was patient he gave his HONEST opinion and when I told him about a few rings that kind of caught my attention, but there was one thing I wanted to change each of them he suggested why not design designing my own exactly the way I wanted with a little bit of each of them. I love that! And today my husband reproposed with a stunning ring that really makes my heart flutter! Nothing will replace the sentimental value of my original ring, but let just say this ring is def an upgrade! Thank Armin! Diamondful will definitely be our family jeweler going forward!

    Reset my engagement ring with Armin and it is exactly how I envisioned it. Beautiful work!

    Custom Diamond Ring upgrade
    Jashua S.

    Armin and his team were amazing! I have nothing but great things to say about him and his team. It was coming up on my wife and I's 10 year anniversary and I wanted to make an upgrade to all the stones. Armin chose the perfect set, quoted a great price, communicated throughout the process and even got it done before Christmas when I dropped it off the Thursday before with no express charges. I told my wife that I was just dropping it off for a cleaning and it brought tears to her eyes when she opened the box and saw it fully upgraded. Armin was able to save the old stones and we will be placing them in a clear resin cast for a memento of the past 10 years gone by. Thank you very much Diamondful and Armin!!

    Armin was amazing! We are very happy with how the engagement ring turned out and the entire process. He was very quick to respond with all of my questions and the ring came in sooner than initially estimated. Definitely would recommend! Thanks Armin!

    Absolutely incredible experience working with Armin. He helped me craft an incredibly gorgeous engagement ring for my now fiancé. The entire process was smooth, making sure that the ring had all my detailed personalizations prior to crafting the ring, and provided frequent updates, and transparent communication with during the process of creating the ring and shipping. All diamonds are IGI certified, and Armin provided all the appropriate paperwork for this incredible engagement ring. The box that he shipped it with is incredibly beautiful pink box with a smooth velvet ring box, that housed the new engagement ring. Thank you Armin with helping me, create lifelong memories as I start the beginning of my new life with my partner!

    If you want an honest, kind & knowledgeable jeweler. I 1000% recommend purchasing from Diamondful. 10/10 Armin is your guy! I was browsing Etsy, came across his page & found my dream ring. To the T, a Toi Et Moi ring with a hidden halo, that was 2 toned! I reached out to Armin who promptly replied. He sent me every detail & was able to get me bigger & better quality diamonds for the same price as the competitor! From the diamonds, to the type of gold, to a rendering of the final product & its dimensions, Armin kept me up to date throughout the whole process & even finished ahead of schedule! What's even better is that he is local & I was able to pick it up! I've only had this ring for a week & I get compliments on it DAILY! Sometimes I just sit in my bedroom and stare at how beautiful it is. presentation? 10 out of fricken 10. It came in a beautifully packaged box (that I will keep forever bc I'm a low key hoarder) with the IGI certificates tucked inside and a cute pink ring box. Greeted upon arrival, Armin and his wife were very warm and welcoming, and made it very easy to converse. He talked to me about how to care for it and even offered to resize if I didn't like the fit. Customer service is top tier & I am excited to make future purchases! The ring is truly a work of art. Thank you for all your hard work Armin & Diamondful team! I LOVE IT

When we arrived we were handed off to David (the owner) with no explanation. The appointment felt rushed and impersonal from the start. David didn't ask basic questions like our names, budget, or where we were in the process, and offered little guidance. We are early in the process, so I was hoping to try on different styles to get a sense of my preferences. But after trying on just a couple rings there was no effort to understand my priorities or suggest alternatives. I felt like I had to push just to see more options. Our 2PM appointment was essentially over by 2:05PM. I left feeling sad and disappointed that such an important and special moment was handled with so little care. Before going here, I recommend looking at the other 1 star reviews -- they are honest and I should've listened.

And boy did she deliver - communication during the stressful holiday season was impeccable, and she kept me updated throughout on our back and forth during the design process. She even managed to squeeze our ring in right before they closed for the Christmas/New Year's break despite a mountain of other clients with similar due dates, and words can not express just how thankful I am!
