Loose diamonds

She’s one of a kind. Her diamond can be, too.

JDC has more diamonds to choose from than any other local jeweler. Plus you’ll enjoy the highest quality, the best prices (starting as low as $100) and our unmatched return guarantee.



Only The Finest

We offer the largest collection of loose diamonds in the Inland Northwest. And not just any diamonds. We work with sources in Africa, Russia, Belgium, Canada and India to individually select every diamond we sell. We’re particular because an invoice that lists industry standards (Carat, Cut, Clarity and Color) simply cannot explain a stone’s brilliance. We reject 99% of the diamonds we see so that you can choose from only the very best and brightest.



The True Best Prices

Other jewelers continually advertise 50% to 70% off. But ask yourself: why’d they mark it so high in the first place? Instead of gimmicks, we believe in offering the best prices every day. Compare our regular prices to the sale prices of big retailers or wholesalers and you’ll see: we sell brighter diamonds for the same money. All of our diamond engagement rings also include resizing and maintenance free for life.



100-Day Diamond Refund

Our diamond return policy is unheard of in the industry. When you purchase one of our diamonds, you get a 100% money-back guarantee for 100 days—just to be sure. So forget about buyer’s remorse. We’re that proud of our diamond quality.



Now & Forever Care

When you buy a diamond and engagement setting from us, all maintenance, sizing, polishing and cleaning are free of charge for life. She’ll never have to worry about her ring. We really do want to be your jeweler for life.



Lifetime Diamond Credit

JDC offers a lifetime return credit on every diamond we sell. You’ll get 100% of the amount you originally paid to use toward anything in store, including custom work. Maybe you would like to reset your original wedding diamond alongside a bigger anniversary stone. Or, how about reusing the diamond in a necklace? Whatever you decide, the option is always yours.
