Description

This 3.04 ct Tanzanite from the Merelani Hills, Tanzania stands out for its uncommon, design-forward shape and its beautifully wearable color. Instead of a standard triangle, the stone is cut as a fancy trillion-style form with two equal sides and one longer side, creating a slightly elongated, modern silhouette that feels unique and sophisticated.

Friendly medium purplish-blue

The gem displays a medium-saturated purplish-blue tone—recognizably Tanzanite, yet bright and approachable. It offers a lively look without appearing overly dark, making it an excellent choice for jewelry that’s meant to be worn and enjoyed in everyday light.

Fancy trillion cut — a modern statement

The asymmetric geometry gives this stone a contemporary personality and opens up creative setting possibilities. It is ideal for:

  • a statement ring with an architectural vibe

  • a modern pendant where the outline becomes part of the design

  • bespoke settings that highlight unusual shapes

A distinctive Tanzanite for creative design

With its elegant color and uncommon fancy shape, this tanzanite is perfect for someone who wants the beauty of Tanzanite—but in a piece that looks truly individual.

A one-of-a-kind fancy-cut Tanzanite from Tanzania—friendly purplish-blue color with a modern, distinctive silhouette.
