Millers International Diamonds & Jewelry Established in 1925 is described as a fast-paced, high-volume fine jewelry manufacturing facility with master bench workers, learning both mastery of design and volume manufacturing. Millers sells products across the nation, to re-sellers and large jewelry corporations, and insists that its jewelers be very experienced and highly skilled. In 2005 Justin Miller graduated from a long, intensive education at the American Institute of Diamond Cutting in Florida and joined forces with his father Doug in the family jewelry business, he vowed to one day open the only retail jewelry store in Portland that cuts their own diamonds, enabling him to offer wholesale pricing direct to the public.
