Blue is linked to divinity and serenity in the diversity of many colors. The color of the sky and the ocean well reflects the beauty of ‘blue color.’ Other than nature, where this color is found, beautiful gemstones like blue sapphire and tanzanite also feature it. While the former is a royal gem known for its exquisite color, the latter is known for its color variation.
Is tanzanite stone the rarest gem?
This beautiful gemstone is the blue-violet variety of the mineral Zoisite. The rarity of the gem owes to its availability. This treasure is found only in one place: under the foothills of Mount Kilimanjaro in Tanzania. The interesting color of the gemstone is due to the presence of trace elements such as vanadium. The color of the stone ranges from lighter to vivid shades of blue.
The tanzanite stone price varies with the 4C’s, making the ones with strong and saturated hue fetch higher prices. These gemstones have been coveted for their rich color, making them valuable stones for high-end jewelry.
