Found in only one place in the world, tanzanite is mined exclusively in the Merelani Hills of northern Tanzania, near Mount Kilimanjaro. One of the rarest gemstones (it’s mined in a site only 4.3 miles by 1.2 miles long), it is trichroic, meaning it can display three colors depending on how the stone is cut and the direction you view it.

Finding beautiful gem-quality tanzanite over 3 carats can be quite expensive, and this gorgeous cushion cut is an exemplary example, with flashes of purple and blue.

The stone's dimensionality is enhanced by the necklace's unique design, framed with trillion-cut diamonds in milgrain settings with a dangling tanzanite drop.
