Our Vision

To commemorate your special occasions with jewelry made just for you. Using the latest design technology and the finest hand selected diamonds and gems, with quality comparable only to the finest jewelry retailers in the world.

Our History

Many years ago while browsing at Tiffany’s I almost bought my "dream ring”. I had just finished my MBA, had a great job offer with a very nice bonus. The ring cost three times more than I spent on my first car. I thought after all this hard work I had earned something special, but my practical side was holding me back.  

I remembered a jeweler acquaintance I had met some years ago, his name was John.  I decided to give him a call.  John educated me about diamonds and jewelry and created my dream ring, at half the price and he did not compromise a single quality aspect.  At that moment I thought WOW, I got more ring then I dreamed of, at a price I could live with, and more importantly it was made just for me.

I was intrigued by the concept of creating high quality jewelry, providing personal service at "affordable" prices, so John and I joined together to build a new type of jewelry company that offered something different; made-to-order fine quality jewelry, with no inventory costs or major overhead to inflate prices.  Our vision was to make each piece of jewelry for the individual using the latest design technology and the hand selected diamonds and gems, with quality comparable to the finest jewelry retailers in the world. We did just that.

That was seven years ago, and thousands of special clients served. Over the years we have evolved our business and expanded to offer new products and services, but our focus always remains the same, fine quality jewelry and personal service.

We are honored when you select Diamond Deign Co. to help commemorate your special occasions with you. Please read our Testimonials from our many valued clients we've worked with over the years to celebrate the most precious occasions.

Our Quality Commitment

At Diamond Design Co. we are committed to Tiffany standards of fine quality jewelry. Our diamonds are hand selected and graded. Our jewelry is precision designed and manufactured, using the latest jewelry technology and we will not compromise our quality standards.

If you’ve ever been to Tiffany’s and seen a truly exquisite piece of fine jewelry, you have most likely been discouraged by your on-line shopping experience thus far. There are so many jewelry websites out there, most peddling the same low quality, mass produced, over priced jewelry. Even the “BIG 3” who are attempting to dominate the Internet, they too are just resellers that pass on their advertising and overhead costs to you. Sure you can have it overnight in a cardboard box. But will it be worth the dollar you paid for it, a year from now, five years from now? When the purchase of fine jewelry is for someone special, including yourself, forget the gimmicks and flashy websites, select fine quality jewelry that is uniquely made for you.

We use CAD design systems and integrating wax milling. Our jewelry is made by us for you. Learn more about How our jewelry is made.
