CAN'T-MISS COLLECTION The Spirit of Aloha Vicente Agor’s new Hokule‘a collection nods to the history of the first Hawaiians—Polynesians sailing to the islands from Tahiti some 2,000 years ago. Hokule‘a is a 30-SKU line of 18k gold and silver styles with sea and sun themes featuring gems like sapphires and diamonds. (The cornerstone piece is a boulder opal pendant with a small surfer-like figure at the bottom center of the stone.) Retail prices for the collection, which evolved from Agor’s sea-inspired Swell collection, start at $750.  (Pictured: Surfer necklace in 18k gold with a 37 ct.
