Professional, efficient, and resourceful!

“Jonathan is a delight to work with. Very competitive priced, he found the stone that I wanted in no time providing me his expert options and guiding me through the process. After showing him an idea of what I wanted, he drafted designs and had the ring turned around within weeks. I know own my dream ring [which has received many compliments]. I’ve since bought a necklace that Jonathan designed, and I look forward to future investments. Jonathan will be the only jeweler that I call.

Integrity, expertise, craftsmanship, and amazing creativity...

“From the moment I walked in with my fiancé to have a custom wedding ring created, Jonathan Siegel not only created what she needed to perfection, but he was part of some of our greatest memories we have as a couple. He isn’t just the finest jeweler we have ever worked with; he is that rare individual who partners with you and became our trusted advisor, artist, and amazing problem solver. He epitomizes all you want in a jeweler and more. Jonathan is truly one of the finest men my wife and I have ever known.“

Highly Recommend Jon!

During our marriage of fifty-two years (so far), my husband and I have twice upgraded my diamond engagement ring with the help and expertise of Jon Siegel and recommend his services without hesitation! As a GIA Graduate Gemologist, Jon has all the technical gem knowledge one could ask for, as well as excellent design ideas and the highest ethics. His diamonds are always GIA certified (the gold standard in the jewelry industry) and his manufacturing shop does beautiful work. Without reservation, I recommend Jon Siegel to anyone shopping for diamonds and diamond jewelry.”
