Gemstones in Washington, D.C

Hi, All; I plan to be in the Washington, DC/Maryland area later this
week into next week, and was wondering if anyone knows if there are
any jewelry/gemstone wholesalers, or a “diamond district”, in the
area - “To The Trade Only” type of places. I’m familiar with Miami,
Atlanta and New York, but not the DC area. Be nice to combine
business and pleasure and make some new contacts. Thanks for any
info…
