Assil Gem Corporation

Mid-town’s diamond corridor runs along 5th Avenue, anchoring firms like Assil Gem Corporation in one of the city’s densest wholesale clusters. Wholesale jewelers here supply everything from broken-down stock to fresh-off-the-plane parcels, and Assil Gem Corporation holds a straight-line address in that zone: 587 5th Ave New York, NY 10017. Inventory seems to shift daily—loose stones, sealed parcels, and batches sized for quick resets—making it a zone where volume and velocity matter more than shopfront presence. Beyond crystals, tungsten and titanium pieces show up on separate lots, sometimes tucked beside classic 14k seed pearls. The trade records clearer deals when paperwork and assays travel with the pieces; a few traders fax certificates forward before the boxes land. On busy afternoons the loading zone outside briefly clogs with carts and hand trucks, neighbors barely reacting to the logjam. Buttons on unrelated hand-held devices chirp at once during rapid-price spikes, so the radio in many offices cracks to the same speculative chatter. Cash floats still matter at certain cash corners, especially when brokers settle mid-video calls from private booths upstairs. Call ahead for pickup or pricing windows: (212) 521-3636.
