The Georgian-era fashion trend of women adorning themselves with fresh flowers was the inspiration for this wildly romantic convertible necklace by Simone Jewels. The deep-blue tanzanite heart—which doubles as the front of a locket—also detaches to become a brooch and pendant. Designer Simone Ng says she’s thrilled that its wearer “can enjoy the exposed back of the gemstone, and also keep something close to their heart in the hidden compartment.”

A stonecutter in Israel chiseled the heart from a hunk of rough tanzanite. The bauble’s gems were set in both Thailand and Hong Kong. “There was quite a bit of coordination between different parties to get the whole piece done,” the designer says, “but this is how most of our pieces are made.”

Elegant Design

Ensuring that the locket was functional—with its hinges hidden—was among the major challenges in bringing the jewel to life. Says Ng: “In order to make the piece transitional meant the mechanisms needed to be done well and be easy to use, without compromising the design.”

The 18k white gold piece boasts a magnificent 14.63 ct. unheated heart-shape blue tanzanite and also features 5.6 cts. t.w. diamonds, 33.42 cts. t.w. Mediterranean pink coral, and a 10.4 mm Tahitian pearl.
