To jewelry connoisseurs, Munnu Kasliwal is as big a name as Cartier or Tiffany: Fans regularly make the pilgrimage to his Gem Palace in Jaipur, India, which has been in the family for 152 years. Yet somehow, the not-quite-perfect shape of the 78 rose-cut diamonds on this double-strand necklace comes off very modern, and very in-your-face. Add 1,153 round diamonds, and that’s 54 carats for $143,125 (at Barneys New York). It’s hard to call anything that costs six figures a bargain, but you won’t get so much dazzle for the dollars anywhere else.
