Defining Diamonds:

Natural vs. Lab Grown

Diamonds can be formed deep within the earth over billions of years or created in advanced laboratories using modern technology. Both options offer genuine beauty and sparkle, but they differ in origin, availability, and cost. At Seagull Diamonds and So Forth, we provide both choices so you can select the one that best fits your values, style, and budget.

• Natural Diamonds – Mined from the earth, each natural diamond is unique, carrying geological history and rarity. Their value often reflects this scarcity and natural formation.
• Lab Grown Diamonds – Created using advanced processes that replicate nature, lab grown diamonds share the same physical, chemical, and optical properties as natural ones. They can be priced lower, making larger sizes more accessible.

Perfect !

“Jonathan Siegel is a jeweler of integrity and excellence. He believes in complete customer satisfaction and offers thoughtful, personalized advice when choosing jewelry. His craftsmanship and service always exceed expectations. Every piece comes with proper certification, full guarantees, and is delivered on time. His prices are fair and reasonable, and his collection is consistently authentic and of the highest quality.”

Professional, efficient, and resourceful!

“Jonathan is a delight to work with. Very competitively 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 now 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.”

Jon is simply a great guy!

"I’ve been working with Jon for many years, and he now has an incredible ability to anticipate what my wife will love. Early on, I purchased an emerald ring as a “stand-in” while he searched for the perfect stone—and he delivered. Jon took back the temporary piece and created the ring my wife had always wanted. Since then, he has designed several exquisite pieces for her. Beyond his craftsmanship and knowledge, Jon is simply a great guy and someone you’ll truly enjoy working with. "
Mary Lou C.

It was a great experience working with Jon

"Jon Siegel recently updated my engagement ring and wedding band. I couldn’t be more pleased with the result. Strangers have stopped me on the street to compliment me on my ring! It was a great experience working with Jon. He was creative, patient, prompt, and trustworthy. A true professional. I highly recommend Jon and hope I am lucky enough to work with him in the future."
