Diaglow

Diaglow deals in diamonds on West 46th Street. If you need accent pieces or melee—necklace chains or stud settings—local jewelers source from here. The business keeps small, specific transactions running smoothly. When setting up a batch order, expect quick turnarounds and clean cuts.

Precision matters in this trade. The team handles sizing, grading, and minor setting repairs without fanfare. Quick appraisals keep projects moving. Finding calibrated stones at short notice is a specialty—if the specs match, inventory appears.

On 2 W 46th St Suite #1200, New York, NY 10036, it sits mid-block beside other jewelry suppliers. Cross Fifth at the end of the avenue, or walk straight from the subway exit—turn left, and the glass door is two storefronts down.

Add contact info once near the end: call (212) 256-1951. The map helps when navigating the side streets—open it before hopping from the A/C between Times Square and Bryant Park. That’s what locals do.
