Jewelry Design Center (JDC)

“We Want To Be Your Jeweler For Life”

Ladies and Gentlemen, if you are searching for a group of people who will work with and for you to find exactly what you want, look no further. Jewelry Design Center (JDC) has an absolutely amazing selection of jewelry, and the staff is exceedingly helpful. The people at Jewelry Design Center makes you feel welcome the minute you walk in the door.

Since 1977, the company has the same philosophy which is when a customer leaves the store, he or she will go away completely satisfied, period. According to their loyal customers, it is what makes Jewelry Design Center (JDC) stand apart.

Jewelry Design Center opened in 1977 as Doug Toone Jewelry Manufacturing. Doug was what you might call the guy behind the guy, providing wholesale services to other jewelry shops in the area. Doug’s son Brian joined the JDC team in 1995 and is currently JDC’s President and CEO. Doug has taken a step back and Brian’s siblings have joined him in this potentially “lost art” of turning stories and emotions into gold — plus many other gems and precious metals — to the tune of about 1,200 tailor-made pieces per year.

They are the largest independent supplier of loose diamonds in the Northwest. Every single diamond at JDC is hand-selected for their brilliance and value because industry standards (carat, cut, clarity and color) simply cannot define a stone’s performance.

Their diamonds are ethically obtained and purchased directly from the source. They work with sources in Africa, Russia, Belgium, Canada, and India to individually select every diamond they sell. Some diamonds can even be traced back to the exact location in the ground where they were discovered! JDC has more diamonds to choose from than any other local jeweler. Plus you will enjoy the highest quality, best prices, and unbeatable guarantee.

When you purchase a diamond and engagement ring from JDC, all maintenance including stone loss, sizing, polishing, rhodium plating, cleaning are free of charge for life. Let the company clean and check your ring every 6 months to ensure your piece stays in the best possible shape and catch problems before they start. This is the best warranty you will find out there. 


It is often confused with the cut. The term “cut” refers to how light is reflected across each stone, although diamonds have been cut to create different shapes and designs. Each of them has its own brightness and clarity.


The cut and how a diamond is cut determines the brilliance or shine of the diamond. Each shape will be cut differently. Before a diamond is cut, all its features are thoroughly examined. The diamond is cut to maximize size, shape, and clarity. For optimal light performance and rarity, you will want a diamond that is cut neither too shallow nor too deep.


Each diamond is distinguished by its natural characteristics. Features that are considered the clarity of a diamond can be stains on the surface or inclusions in the stone. Sharpness is assessed by the number and types of these features. Producing and owning a perfect diamond is really difficult and rare. 

Carat Weight

Carat is the unit of measure. It is used for the weight of a diamond. When comparing two diamonds, please note that just because one is twice the carat weight of the other does not mean that it will appear to be twice the size.


The natural body color of a diamond. If there is less color in a diamond, it allows more light to pass. It allows releasing more brilliance and fire. The scale runs from D (colorless) to Z (light yellow). If the is less color, it means that the higher the rarity, and the higher the value.

Custom Jewelry Design

There is nothing quite like creating something uniquely you. As the largest jewelry design and manufacturing center in the region, JDC can create any custom piece you desire. From finding the perfect center stone to sketching up design ideas, this company is the expert so you don’t have to be. They do this every day and want to make the process worry-free.

Why should you choose a Custom Design?

  • You have the jewelry you no longer wear or jewelry is not your style
  • You have a collection of loose stones that you would like to use
  • You have specific imagery or symbols that are special to you
  • You would like to remake or restore an antique or estate piece
  • You experienced a deep loss you would like to memorialize
  • You cannot find the exact style you have been wanting

There are some necessities you should bring with you for your first appointment. These are any jewelry, stones, or metal you would like to use; sketches, Pinterest boards, or photos of inspiration; ring size, your imagination, and an open mind!

Designers of the company gently walk you through the process, work with your budget and timeline for your project, and be in constant communication using the methods that work best for you. Because they complete projects on-site, there is less waiting and you are able to see and interact with a wax version of your piece before jewelers start working on it, in case there are last-minute changes.
