The Green Tanzanite: A Unique & Captivating Gem

by Madonna

Tanzanite, renowned for its striking violet-blue hues, is a gemstone that has captured the hearts of many jewelry enthusiasts and collectors. However, beyond the classic violet-blue shades lies a lesser-known variety known as green tanzanite. In this article, we will explore the enchanting world of green tanzanite, delving into its unique characteristics, origins, and the reasons behind its growing popularity in the world of colored gemstones.

The Fascinating World of Green Tanzanite

Green tanzanite is a captivating gemstone known for its distinct green coloration, which sets it apart from the more commonly recognized violet-blue tanzanite. This rare variety has garnered attention for its unique and vivid shades of green, making it a gemstone of increasing interest among jewelry connoisseurs and gemstone enthusiasts.


Green Tanzanite’s Color and Characteristics

Green tanzanite is celebrated for its vibrant green hues, which can range from a pale, almost pastel green to a deep, intense forest green. The green coloration is a result of trace amounts of the mineral vanadium in the tanzanite’s crystal structure. The specific shade of green can vary from gem to gem, and the most valuable green tanzanites are those with an intense, evenly distributed green color.


The optical properties of green tanzanite are similar to those of its violet-blue counterpart. It exhibits trichroism, which means it can display three different colors when viewed from different angles. In the case of green tanzanite, these colors may include green, blue, and a secondary hue that could be yellow or brown.


Like all tanzanites, green tanzanite is a variety of the mineral zoisite. It has a good level of transparency and often showcases excellent clarity, although inclusions may still be present. The gem is relatively durable, with a hardness of around 6.5 to 7 on the Mohs scale.

Origins of Green Tanzanite

Tanzanite, in general, is primarily found in a single location, the Merelani Hills of northern Tanzania. This region is renowned for its tanzanite mines, which have been the source of this gemstone since its discovery in the 1960s. The green tanzanite variety, like violet-blue tanzanite, originates from these mines.

The geological conditions in this area, such as the presence of vanadium and other trace elements, are responsible for the formation of both green and violet-blue tanzanite. However, green tanzanite is relatively rarer compared to its violet-blue counterpart, which adds to its allure and value.

Investing in gemstones, including green tanzanite, is a complex and speculative endeavor that requires careful consideration and research. Whether green tanzanite is worth investing in depends on various factors:

1. Rarity and Quality: The value of green tanzanite is closely tied to its rarity and quality. Exceptional green tanzanites with vivid, evenly distributed green colors and high clarity can appreciate in value over time. However, not all green tanzanites possess these qualities.
