Gemstones are said to be one of the earth’s prettiest treasures. People all over the world have appreciated them for their beauty and rarity throughout history. They are commonly used as decorative ornaments and for their religious value. Gemstones have always been respected for their healing powers too. All gemstones are found raw and beautiful but when gemstone suppliers like KGK Group present diamond, ruby, or sapphire, these gemstones possess a distinct beauty and become special in their way. But some gems are rarer than others and that significantly increases the value of these rare gemstones. Other important factors that define the value are size, grade, and color. Gemstone wholesale supplier and gemstone supplier retail KGK Group has listed 5 rare gemstones on Earth. 

TANZANITE

Found in Northern Tanzania this is relatively a new stone and unlike most gemstones that have a variety of locales, this doesn’t have one.

Taaffeite is a light violet gemstone that was discovered in 1945 by Australian gemologist Richard Taaffe, it is a rare gemstone that most people have never heard of due to its rarity.
