Collection Debut: Spiculum Diamond Jewelry by Khai Khai



New jewelry designs that cast trillion-cut stones in starring roles

Haim Medine of Khai Khai was toying with the idea of the Spiculum collection last year in sales meetings when buyers gave him an enthusiastic go-ahead to flesh out his sharp idea.

He expanded on the original three styles to today’s 30 SKUs, all showcasing trillion cuts—which Medine calls Arrows—in 18k gold. All stones are VS or better in clarity and range in color from G to D, and the name Spiculum in Latin means a sharp, pointed crystal, “especially of ice,” he explains.

“When I first came across this specialized trillion-cut diamond nicknamed the Arrow, I felt an immediate bond to the stone,” Medine continues. “Since this unique cut puts a modern and refreshing spin on age-old diamond grandeur, I wanted to focus on creating a foolproof blend between timeless elegance and contemporary style.”

Pieces have already begun shipping to stores—including Fivestory in New York City and Ron Herman in Japan—and buy-in is upwards of 10 pieces. Retail prices start at $1,500.
