Oscar Platinum & Co Inc

Jewelry stores line the block, but not all of them make what they sell. Some just shuffle inventory; others actually shape metal and stone into something new. Oscar Platinum & Co Inc falls into the latter camp—manufacturing pieces in the same building where they’re eventually displayed.

Their workshop sits at 36 W 47th St # 1400, a floor above the Diamond District’s usual retail frenzy. That address puts them steps from suppliers who’ve fed the city’s trade for decades; proximity matters when your raw materials arrive by the gram. Clients who prefer custom work over off-the-shelf designs tend to show up here, knowing the process starts with a conversation rather than a showcase.

Questions about timelines or materials get answered directly—no middleman, no markup for someone else’s labor. Ring sizing, stone setting, and platinum casting are routine tasks for them; the phone rings at (212) 382-0463 when someone wants to skip the retail markup and go straight to the source. Orders range from single heirloom pieces to small production runs, all handled in-house.

Directions to the office are best pulled from the map listing—elevator banks on 47th can be tricky if you’re not used to the building. Once inside, the focus stays on the workbench, not the view.
