Unlike most Internet jewelers, at Diamond Design Co. each piece of jewelry is carefully designed and crafted by our in-house jewelers.

Fine quality jewelry should come with fine quality service
Signature Services by Diamond Design Co.
With so many choices in the marketplace, we’re honored when you select us to help commemorate your special occasions. We value your confidence and take this responsibility very seriously.
After decades of experience in the jewelry industry, we recognize the discouraging trend 
affecting online jewelry shopping. The ease of creating a website and reselling a catalog of jewelry has inundated the marketplace with resellers of mass produced jewelry, leaving a huge gap in the quality, customer experience and service side of one of the most important purchases you’ll make online. Who can you trust?
First and foremost, we are jewelers not resellers, and we take great pride in the jewelry we make for you. A finely crafted piece of jewelry needs to be well cared for. With this in mind, we created the Signature Services Membership program, not only to take care of your precious jewelry item, but also to ensure all your jewelry purchases from Diamond Design Co. will be made with confidence of knowing that we stand behind the jewelry we make.
