IDEX USA Inc

Between the buzz of Times Square and the polished storefronts north of Bryant Park, IDEX USA Inc makes its home on the 16th floor of 7 W 45th Street. Here specialists move gemstones and precious metals to the trade without fanfare or frills. Trade shows and design tables sit beside quiet conversations about cut and alloy, all in the same shimmering middle of the block.

They take custom orders, source specific cuts for designers, and supply settings ready for the bench jeweler’s torch. Repairs and appraisals pass across the same desks where stock shifts daily—no storefront brass, just the click of a zipper on a courier bag. The building’s elevator deposits visitors directly outside a frosted-glass door marked 1602, just past the security desk.

Call ahead: (212) 382-3528 before riding up. If the trip feels tricky, the map can guide you straight to the floor. Midtown’s grid may shuffle taxi cabs past the door, but the lobby always sits where you left it.
