Tanzanite and Diamond Ring in 18K White Gold

Rare and valuable, tanzanite is also found in only one place on the planet: the Merelani Hills of Tanzania, in the shadow of Mount Kilimanjaro. One of the world’s most beautiful blue gems, tanzanite is actually pleochroic, showing three different colors when viewed from different directions: purple, blue, and bronze. As you move, you’ll see the colors flash. Discovered in 1967 and named by Tiffany & Co in tribute to the beauty of Tanzania, tanzanite quickly became one of the world’s most popular gems. When you gaze into its mesmerizing depths, you’ll understand why. Tanzanite is a birthstone for December and the 24th anniversary gem.

Creating 18K white gold is jeweler’s alchemy. To make luxurious 18K white gold, 75% pure golden yellow gold is alloyed with 25% white metals, usually silver, zinc, or palladium. These metals also increase its durability and hardness. To get that bright white shine, most 18K white gold jewelry is plated with rhodium, a platinum group metal.
