Color: Identifying Iolite from Tanzanite
Tanzanite generally exhibits a deep sapphire blue with a noticeable violet undertone. On the other hand, iolite ranges from light to deep blue, sometimes showing a yellow-grey or even a clear hue from different angles due to its strong pleochroism.
Comparing the Hardness of Iolite and Tanzanite
Here, iolite slightly outperforms tanzanite. On the Mohs hardness scale, which measures a gemstone’s resistance to scratches, iolite scores between 7-7.5, while tanzanite falls marginally lower at 6.5-7. Iolite is slightly more resistant to scratches and everyday wear and tear than tanzanite.
Physical Properties: A Key to Differentiation
Another key difference is their crystal structure. Tanzanite belongs to the orthorhombic crystal system, while iolite belongs to the monoclinic crystal system.
Pleochroism in Iolite and Tanzanite
Iolite and tanzanite exhibit pleochroism, but the effect is much more pronounced in iolite. Depending on the viewing angle, this fascinating gem can display blue, grey, and yellow-brown colors. Tanzanite, on the other hand, usually shows a range of blue to violet hues.
Clarity and Luster: Iolite vs. Tanzanite
Tanzanite and iolite are usually found with excellent clarity. Still, tanzanite often comes out on top and is commonly eye clean. The luster of tanzanite is also typically higher, displaying a glassy to vitreous luster. At the same time, iolite usually has a vitreous luster.
Pricing: Iolite and Tanzanite
Tanzanite tends to be more expensive than iolite due to its demand and limited supply. However, prices for both gemstones can vary greatly depending on factors like size, quality, and color saturation.
Iolite and Tanzanite in Jewelry
Iolite and tanzanite make stunning jewelry pieces but have different hardness levels. Being slightly softer, tanzanite is perfect for earrings, necklaces, and others less exposed to wear and tear. On the other hand, iolite, being a bit harder, can be used in rings and bracelets.
Source or Origin of Gemstones
Tanzanite is found exclusively in Tanzania, near the foothills of Mount Kilimanjaro. Iolite, however, is located in several locations worldwide, including India, Sri Lanka, Madagascar, and Brazil.
Metaphysical Properties of Iolite and Tanzanite
Iolite and tanzanite have unique properties for those interested in the metaphysical world. In this case, iolite is often associated with guidance and inner strength. At the same time, tanzanite is said to foster spiritual growth and enhance communication. However, aqua gems tend to share certain qualities.
How Cut and Shape Can Differentiate Iolite and Tanzanite
While the cut of a gemstone doesn’t necessarily determine its identity, specific cuts are more popular for certain stones. For instance, tanzanite is often cut into various shapes to enhance its color. In contrast, iolite is typically cut to reduce its visible pleochroism.
