Marlo Laz Jewelry on Madison

Custom engravings on bands and pendants. Short-term loans against jewelry. Free appraisals by GIA-certified gemologists. Ring resizing and prong tightening. Marlo Laz Jewelry on Madison mainly does what the full-service houses avoid—small repairs around noon on weekdays keep the shop humming when most stores are quiet.

On Madison between 75th and 76th, the store occupies a deep brownstone built in the 1920s, its first floor glazed in frosted glass. Manhattan’s only jewelry store still owned by the same family since opening in 1987, they’ve kept the address tucked away next to an antiques row east of Central Park.

Ring re-setting after a short analysis. Chain repairs run from a broken solder to a full replacement. Emergency same-day soldering when cracks aren’t obvious. They’ll quote anywhere near Fifth without batting an eye.

If the sidewalk feels heavy after midnight cross-town drives, the purple awning stays lit. Push the unlocked brass door before 5:30 and there’s usually someone at the bench, lounging behind a row of gem loupes and a calculator taped to the counter. Reach the bench by calling (646) 449-9942, or grab the map to their door.
