The ADC Difference

Affordable Luxury

Despite what you might think, our personalized, custom process almost always costs less than buying a piece of manufactured jewelry. It’s the smartest way to buy jewelry. And, as you’ll discover, the most enjoyable. This is why our customers come back to us again and again.

A No Pressure Co-creation Experience

Coming here is not an act of shopping. It’s an act of creation. Before gold, silver, or diamonds, there is imagination.

Most of our competitors are commercial stores with commission based employees, focusing their attention on transactions and margin growth. We answer only to our clients– which enables us to focus all of our attention on our craft. Our promise is to continually re-imagine what can be done with diamonds and to collaborate with you to create jewelry that is unique.

The Best Diamond at the Best Price

No need to shop around. We offer a direct channel into the wholesale diamond market which allows us to guarantee that no one will beat our prices.

Lifetime Care Included

We help you protect your investment with free adjustments, cleanings and appraisals.

Sustainable and Ethically Focused Business Practices

Our commitment to sustainability extends to ensuring that our jewelry is crafted—and our precious materials procured—in a responsible and sustainable manner. All ADC suppliers are expected, at a minimum, to conduct business in an ethical manner and to comply with applicable laws and regulations.
