For more than 50 years, E.D. Marshall has been recognized as the top spot in Scottsdale, Arizona for selling diamonds. Located off Scottsdale Road just south of Shea, we're proud to be one of Arizona's largest estate jewelry buyers, offering the best prices for diamonds and diamond rings. That's how we've earned the title of being #1 in the Scottsdale and Phoenix area.

Unlike many other diamond buyers in Scottsdale, we don't act as a "middleman," which usually means lower prices for sellers.

Here's what makes E.D. Marshall different and how it works:

  • Thorough Diamond Assessment
  • No-Pressure, All Cash Offer
  • Instant Payment To You
Call us with any questions.


We recently sold a diamond ring and a Rolex watch we hadn't worn in years. They offered us quite a bit more...
