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

A native of Israel, Alon attended college in the Midwest and didn’t 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 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 from 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 showroom.

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
