All You Need to Know About Tanzanite’s Spectacular Colors and Rare Nature
One of the rarest gemstones in the world, tanzanite can only be discovered in a small area of Tanzania. This stone is highly sought after for usage in jewelry and other keepsakes because of its rareness and vibrant colors. What are the gem’s secret features that make it so valuable? Let’s examine tanzanite’s optical characteristics to understand why this valuable gem is so rare. This website has all you need to learn more about this topic.
When light strikes a tanzanite crystal, its structure separates wavelengths that are then absorbed to different degrees. This optical phenomenon is known as pleochroism. Looking at a tanzanite from one angle reveals a lovely blue, but turn it slightly to see a rich violet hue. Some crystals even display three colors depending on your viewing position. No other gem exhibits such dramatic color shifts based solely on orientation.
Pleochroism in tanzanite is a product of both its chemical composition and crystalline structure, and it allows for a wide variety of unique color gradations. Its main constituents, calcium and aluminum silicates, divide light wavelengths. The different crystallographic orientations then absorb various hues when viewed from various angles.

The rareness of tanzanite is almost as fascinating as the beautiful colors it reveals. Near Mount Kilimanjaro, in a tiny mining area, comes more than 99% of the world’s supply. In contrast to other blue stones like sapphire, tanzanite exclusively develops in this tiny part of Tanzania. Finding large crystals fit for exquisite jewelry has become harder as mining operations have increased in recent decades to unearth more of the prized stones. Natural tanzanite is highly sought after due to its investment grade and inimitable beauty, while synthetic lab-grown tanzanite can satisfy the need for more numerous smaller stones.This page has all the info.
Tanzanite’s amazing color-changing properties, combined with its rarity, have made it a highly sought-after gemstone. In spite of being more expensive than other gems on the market, collectors are drawn to them because of the prestige and investment opportunities that come with their scarcity. When set in an engagement ring, tanzanite’s symbolic meaning deepens since it represents a bond that will last a lifetime through its ever-changing colors. You can read more about the subject here!
There are only few other blue gemstones that can compare to the rarity of tanzanite. While blue topaz, iolite, and sapphire often undergo heat treatment or diffusion to improve its color, tanzanite does not. Its singular chemical composition and structure allow for the formation of a wide range of colors. Tanzanite is so rare that it even stands out among the most expensive jewels. From its single deposit site, less than a million carats of rough tanzanite is extracted annually. This gorgeous blue cannot be found anywhere else because it comes from a little region that makes up less than 1% of Tanzania’s total area.
