Fashion flagships and high concept restaurants have supplanted the messy business that gave New York's Meatpacking district its name, but even among the new guard, Doyle & Doyle stands out. The vintage, antique and estate fine jewellery boutique has a following that includes hashtagging millennials and veteran collectors. The second installment of its Vault Series - in-store exhibitions highlighting specific genres of jewellery - will attract even more admirers. Dubbed "Sentimental Rings: From Birth to Death and In-Between", a curated display of 34 pieces, dating from 1650 to the mid-20th century, gives an overview of rings created to represent personal meanings.
