About Us

Our story began in 1996 when Alon Spektor and Dave Anderson combined their knowledge to open The Diamond Room.

Alon, a native of Israel, attended college in the Midwest but did not realize his passion for diamonds until shopping for earrings at the Diamond Exchange in Ramat Gan, Israel. Upon his arrival back to the U.S., Alon studied the local diamond market and decided to establish the first wholesale diamond business in Sioux Falls, South Dakota in 1984.

Dave’s jewelry career began shortly after he graduated college and began managing nationally and independently owned jewelry stores across the region. After a change of careers to pharmaceutical sales, Dave realized his true interest for the jewelry business and partnered with Alon to open The Diamond Room.

In 2017, Dave decided it was time to retire from the jewelry industry. Over his 21 years at The Diamond Room, Dave made many lifelong relationships with his customers. The decision to retire was difficult and Dave knew he needed the right person in place to continue taking care of his loyal customers. He had that in mind when adding Justin to The Diamond Room family.

Justin Shatto joined The Diamond Room team in 2013 and he quickly learned the ins and outs of the jewelry industry, developing a passion for gemology. His attention to detail and genuine respect for his customers makes him a great fit to continue in Dave’s footsteps. He is working towards his gemology degree to better serve the community as a certified gemologist.

Today, The Diamond Room is known throughout the region for having the areas largest selection of loose diamonds, unique jewelry designs and exclusive watch lines you won't find anywhere else
