At The Diamond Gallery of Naperville, we take this responsibility seriously, with special care and attention to detail in each custom piece of jewelry we create. In an industry that is consumed by mass production and distribution of jewelry, we are committed to making fine quality custom made jewelry one piece at a time, and made by a team effort of both the client and us working together. When your two girlfriends and you "bought it a Harrod's" then that is like walking into a wedding reception with the same dress on as your two friends!

We are THE custom jewelry design specialists in Naperville and the surrounding areas with over 70 years of combined jewelry experience on staff and now utilize the most modern digital custom design software in the business. Each of The Diamond Gallery of Naperville's sales consultants goes through constant training to be able to serve you quickly and expertly.

Diamond from a grandmother or mother? let's make something new with it simply  and affordably!

"A fine quality piece of custom jewelry is not only distinguished by its precision of design, but more importantly by the beauty and brilliance of using fine quality diamonds and gems."

To achieve the finest quality and unbiased diamond grading, our highly trained diamond professionals use the most advanced technology available, including a proportion analyzer, colorimeter,  and ASET machine when necessary which are set at strict specifications by GIA and AGS parameters.

All of our loose diamonds, including those that are certified by GIA and AGS, and EGL, go through our strict proportion and color grading process, this ensures the finest quality ideal cut diamonds, even the smallest of diamonds in your jewelry piece are hand selected and graded this way.

While precious gems and semi-precious rare stones are graded differently, we take the same care in selecting and matching only the finest colored stones for any custom made jewelry. If you want just a tough of yellow gold in your white gold engagement ring it's no problem.

Precision 2D & 3D CAD Design Technology

We are proud to be one of the few designated jewelers in the country offering the most advanced form of custom designed jewelry in the world, the 3D Jewelry Design. Once the diamonds and gems are selected, the piece of jewelry is designed to exacting specifications for the stones, ring size, and style. By utilizing the power of 3D Jewelry Design technology we ensure a jewelry piece that is created for the exact stone measurements, ensuring a precise, quality design each and every time. Imagine this for a minute....you see a designer jewelry diamond ring and they created that with a 3D design program and then slap their name on the ring and charge you $4000 for a ring which will can do exactly the same if not better from the exacvt same jewelry design software and your price of $2500! It's not like Jon Paul from Montreal is sitting there making each ring one at a time and that's why it's $4000. It's the same program!! It's your money.

Our new custom software is for quick digital imaging and our 3D CAD design software is fully integrated with a wax-milling machine. The milling machine is networked with the software. It cuts a perfect wax mold of the jewelry item, and it is done digitally. The wax is then used in the metal casting process. Each step is done with the most precise calibrations possible.

Our casting methods are the most advanced in the industry. Our proprietary methods create the most superior settings available anywhere. We also can use an induction machine casting process that nearly eliminates porosity concerns and creates a denser cast then other methods, resulting in heavier and sturdier settings.

Lastly, we employ only the finest, professional setters to ensure not only the security of the stones, but flawless channel and prong setting without gaps. We do all the final finishing and polishing until the piece is perfect. We rely on strict quality control at every step for each piece. Your satisfaction is guaranteed.

We believe that a piece of diamond jewelry designed and manufactured using these advanced techniques and technologies, is far superior to the mass produced jewelry found in the market place. And because we do not have to stock this type of designer inventory, our prices are well below those found in the high-end jewelry stores where they have to carry many pieces which never sell in order to carry that designer diamond jewelry line. we carried many of these designer diamond rings and found that they were using the same CAD program we are so why pay 30% - 40% more to have their name on it! We can now create any piece from a digital picture of jewelry or any magazine picture also, and you can put your personal touch to a design of which then you created! We now have the capability to make any wedding band you want with such ease that no longer do you have to settle for any band that almost looks good!

With our service and our new technology we can create any look you have found anywhere. We also have an extensive list of customers from out of state, of which we have known for years, and they are presently taking advantage of this fabulous technology. With e-mail we can do a lot of work on-line as if we were together in person!
