Owner Alon Spektor
Alon Spektor’s journey in the jewelry industry began in 1984 at his home in Sioux Falls, where he started Spektor Diamonds, a wholesale diamond business. By 1996, his business evolved into a partnership that launched The Diamond Room. Now, in 2024, he’s celebrating 40 years of success and innovation in the diamond industry.
The Diamond Room by Spektor has become a cornerstone of Sioux Falls because of its commitment to quality jewelry and the community. This dedication has earned it the title of Sioux Falls’ Local Best for 18 consecutive years and the No. 1 Jewelry Store for the past four years. These accolades stem from its exceptional service and products and Alon’s personable approach to selling. He prioritizes building lasting relationships, making it easy for customers to trust his expertise and openness.
The Diamond Room offers the largest diamond selection in the Sioux Empire and a diverse range of jewelry for all budgets and is bolstered by the robust backing of Spektor Diamonds wholesale arm. This unique structure allows The Diamond Room by Spektor to cater comprehensively to its clientele.
The business also caters to the community and regularly contributes to significant local organizations, including The Boys & Girls Club, the National Kidney Foundation, Sanford Legends, and Make-A-Wish, and strives to support smaller, community-specific initiatives.
