JK Studio

Custom jewelry isn’t something you stumble on every day. JK Studio operates from a booth on the second floor at 20 W 47th St Booth 20R, New York, NY 10036, a building most New Yorkers associate with wholesale diamonds and watch repairs. The designer handles everything from engagement rings to heirloom redesigns—no mass-produced catalog, just one-off pieces that start as sketches and end as platinum or gold settings. If you need a repair, resize, or a completely new design, the same hands that draw the concept will shape the metal.

People who prefer a direct conversation can call (914) 768-3457; the number rings to the bench, not a distant office. The Diamond District location means you’re steps from other specialists—bench jewelers, gem dealers, appraisers—so a single trip can cover multiple tasks. Directions to the booth are easiest via the building’s elevator or stairs; the map here keeps the walk precise: https://www.google.com/maps/place?ftid=0x89c25971b1d63e81:0xd46601e2a10e6122. A quiet corner in a loud neighborhood, basically.
