  • Sathi Couture Stack Rings

    "Nick has made five custom rings for me and I've purchased two others. He's also made five earrings for me. I've also purchased two pairs of cuff links. I couldn't be happier with everything I've gotten there. And not only is the jewelry spectacular, the store is stunning and everyone there is incredible. I'm happy to be a regular customer for nearly 25 years."

    "I can't say enough about these wonderful people! The quality and care for product and customer is unseen today and these people GOT IT! I have yet to see more beautiful or original pieces, can't wait for the holidays!"

    – Kim C.

  • "Excellent selection, great service, and unique designs. Nicholas at Patronik has a fine selection of jewelry, including his own designs based on gemstones he has personally selected from around the world. They have items from a few hundred dollars to tens of thousands. Definitely worth visiting, especially if you are looking for something special that's different from run-of-the-mill."
