Don’t expect trendy bangles or bib necklaces at jewelry designer Guy Rozenstrich’s second boutique (the original is in the West Village). The classically styled brand is all about timeless pieces, and the sleek, 400-square-foot space reflects the simple aesthetic in its minimalist, all-white decor. Everything in the store, from the velvet-lined glass cabinets to the elegant gold padlock charm bracelets ($395) showcased inside them, was designed by Rozenstrich himself. Get monogrammed gold ($195) or pavé diamond-encrusted rings ($595), earrings ($185–$925) and necklaces ($225–$695), or invest in a carefully curated vintage piece, such as a Victorian gold owl ring ($2,650). While ladies have the largest selection, guys can score funky silver snake- or griffin-embossed cufflinks ($195). If you’re still left wanting more, meet with Rozenstrich for a personal consultation, and he’ll design, render and handcraft a piece for $500 plus the cost of materials.
