    The top and bottom prongs are uneven and crooked.
    Chang Z.

    My fiancé and I brought two rings in to make a custom engagement ring. The process was initially great, we were provided a sketch and David helped us design a ring. However, the ring came back and the center diamond was not properly set (it was moving and loose). This required reinforcement and additional prongs. The prongs he then added were uneven and crooked (pictured below). I ended up having to replace the entire head for an extra $400 because I did not feel comfortable taking it back to him again. He had the ring the second time for 4 weeks without any communication about when it was to be done and only responded when my fiancé reached out. A few weeks after my ring was fixed by another jeweler, I asked for return of the unused materials from my 2 old rings. We were told they had been disposed of already and that we were given a credit, which was never discussed or agreed upon in our initial meeting. I think the jeweler is always supposed to ASK what you want to do with the remaining materials as some pieces have sentimental value, as did with my old ring. What was supposed to be a memorable experience turned out to be stressful and sad. I usually don't write negative Yelp reviews but this was a horrible experience. I would bring you jewelry else where.

    David is the best. Ethical, precise, offers fantastic customer service, and just really awesome. Every single piece in this picture is his creation. I had asked for simple, understated elegant--and he delivered. I had already referred one to his shop and will certainly refer many more. Thank you very much, David!

    Friends of ours who recently got married recommended Dave to us for my fiancee's wedding band. They had a great experience with him while he crafted their wedding bands, so they highly recommended him. After working with Dave, we're glad that we took their recommendation! My fiancee's engagement ring is a well-worn antique 1920's Art Deco ring. We needed a wedding band that would conform to the curves and look of the ring, but also look nice worn alone. We had some idea of what we liked and showed Dave some pics of a couple of rings that we'd found online. He was able to design a ring that is PERFECT!! With the budget that we had to work with, we feel like we got a ring that really over-delivers. It's sitting in her drawer until the wedding, but she can't wait to start wearing it. We'll go back to have Dave re-size and touch up the antique engagement ring to bring some of its detail back to its former glory, and we expect to get the same friendly, casual, caring, detail-oriented service we got the first time around. Thanks for the great work, Dave!!

    David at The Mercurius helped me create this new ring from a gifted piece of family jewelry. So pleased!

    Last winter, my mom gave me a ring she had purchased decades ago in Brazil. The oval citrine was lovely, but the setting didn't suit me. So I reach out to David at The Mercurius about designing a new ring around the stone (and also using two small citrine earrings I had purchased on the same Brazilian trip). While I have a strong sense of my personal style, I had never commissioned a custom-designed piece of jewelry before. I am beyond thrilled with the results! Rather than a sentimental ring I would never wear, I now have a beautiful ring I plan on wearing daily. The price was reasonable and David listened to my concerns: That it sit high enough to nestle against my chunky wedding band, that there be no prongs to snag my clothes, that it have symmetry, a mix of gold and silver (he used the gold from the original setting, which helped keep the cost down), and a hand-wrought look. I'm delighted with the result and my mom is delighted I found a way to wear the stone. The design process was a great experience - recommend!

    Earrings

    I wanted to upgrade my daily earrings, and I found a design I liked, but not with the specifics I wanted. David was amazing to work with, and delivered! I wanted these in 18K gold with diamonds, I wanted the backings to be flat so they don't poke, and I wanted them to be really tight without risking falling off so I could run, shower, and sleep without ever taking them off. David spent a good hour consulting with me in their very welcoming home (we brought our toddler too, and they were super accommodating). Alisa was also very responsive in communicating with me. They also fixed my husbands necklace for free with my order. The price was very fair, cheaper than mainstream companies to get exactly what I wanted, and timely. I will definitely use David in the future for my jewelry needs.

    Great experience, would strongly recommend. We came in with some old rings and a really vague idea of what we wanted and David did a fantastic job designing something for us. Couldn't be happier with how they turned out!

    The 4 feathers on each of our bands are hand etched and unique. Mine is white gold and his is titanium. I love our rings!

    Dave is rad! If you want unique, one-of-a-kind jewelry, Dave is your guy!!! He made our wedding rings and every time I look at them I fall in love all over again. The design process with Dave is uniquely personal (which alone is worth the 5 stars!) and really brought out the best intention for what we wanted. My husband and I didn't really know what kind of rings we wanted at first but Dave helped guide us with his vast jewelry knowledge to rings we both love! He met with us and just starting talking with us to brainstorm what elements were important to us. We were using the stones from a very special family heirloom and ultimately, with Dave's great eye for design, we developed my bands with elements that honored the original heirloom! After meeting with us, and sketching out several ideas based on our conversations, Dave created a mold for the rings we decided to move forward with. Every step of the way, I was really stoked with Dave's honesty and understanding about our wishes. He was never pushy but listened and worked through the design with us. His expertise with materials and his amazing eye for unique elements made for our most beloved wedding rings. I can say more and more, but just go to Dave!!! It was a wonderful experience and worth every penny to have such one-of-a-kind, meaningful rings! Thanks, Dave!

    Mom's emerald cut diamond and sapphires. I wanted the ring to be 18K gold.

Apparently diamonds are cheaper in certain areas because of competition and availability which is understandable. It is your traditional Asian owned jewelry store. They had a small selection, but we were able to find the perfect bangle. It would have been a couple thousand more if I had bought it at an American store and at least 5,000 more if I bought it at Tiffany's or Bailey, Banks & Biddle. I just loved it. So simple and elegant. They let us pick out our diamonds and it was made then and there. They will work around your budget and if you have cash, even better. I think we got a fabulous deal. So much so that my mother was able to get a gorgeous diamond necklace for herself. The service is great and they even cleaned all our other jewelry while we waited. I don't think I can go back to shopping in an American store. You just don't get the greatest bang for your buck.

    Oh thank goodness for Esqueleto and their amazing engagement rings. Incredible designs, especially…read moreif you're looking for something "alternative," not super traditional, or not overpowering/ clunky. We had STELLAR customer service from LK, who was so lovely and patient. When I told LK I wanted a low profile ring, LK knew exactly what I meant, showed me those exact types of rings and answered my millions of questions. They let you look at a few at a time so you can really compare the rings to each other. I never felt rushed to hurry so they could help the next customer and I never felt pressured to make a choice. They understand that this is a big decision ($!) that warrants lots of window shopping and that you need time to shop around and compare rings & prices. The place is very upfront about pricing and helps you take pictures of the rings, their prices, and the item code. This makes it so much easier to keep track of final prices, makes it easy to compare prices, and makes it easy for your partner to go back without you and get the exact ring you want :) Thank you LK!

The resizing process was very strange, multiple resizing tools were used, leading to confusion. The ring was resized incorrectly, so they offered to resize again. Generally at this point, the fee for resizing should be refunded. During the process the ring was resized incorrectly several times. There was no communication through out the process. After the ring was resized correctly, the Opal came back damaged and there was a flaw in the band. There was no communication about anything, the customer service is severe lacking, especially for a luxury goods dealer. The entire experience has soured my view of Esqueleto, I will never refer anyone, if I know anyone who is thinking of purchasing through them o would strongly suggest against it.
