3.14 ct Emerald-Cut Tourmaline & Diamond Pendant Necklace – 14k Yellow Gold

14k yellow gold · 1 emerald-cut tourmaline, 3.14 ct · 1 diamond, 0.11 ct

Tourmaline comes in more colors than almost any other gem, and it has a quirk that makes cutting it a real skill: it is strongly pleochroic, meaning its color shifts depending on the direction you look through the crystal. Cutters choose the orientation that shows the best color face-up, and the long, open step facets of an emerald cut are one of the best ways to let that color show cleanly.

At 3.14 carats, this tourmaline is a true center stone, with a single 0.11-carat diamond as its accent. Tourmaline sits at 7 to 7.5 on the Mohs scale, durable enough for a pendant you wear often. It is also October's birthstone, alongside opal.

Clean it with warm soapy water and a soft brush, and keep it away from sudden temperature changes.
