Four Gemstones Rarer Than Diamond

[PinkDiamond]

From the American Gem Society, here's one on 4 gemstones that are rarer than diamonds, although I must say there are so many diamonds that a lot of other gemstones are rarer; such as bixbite as one example. The tanzanite ring they show is fabulous, as are the paraiba earrings, but the alexandrite they show is blue on my screen, with purple undertones instead of the usual reddish color that changes to green. Is it just my screen or is it basically blue on yours too?

"Diamonds are well known for their rarity, but did you know there are other rare gemstones? Get ready to learn some interesting facts on four gems rarer than diamond.

Tanzanite

Tanzanite is a stunning blue and purple variety of the mineral zoisite that is only found in one area of the world, Tanzania, a small country in East Africa. When viewed from different angles, tanzanite can display various colors like violet, green-yellow, and even brown. Though most tanzanite goes through heat treatment to produce its attractive blue hues, this treatment produces a stable color that makes this gem desirable.

Alexandrite

Often described as “emerald by day, ruby by night,” alexandrite is a rare variety of the mineral chrysoberyl that has color-changing abilities. Due to trace amounts of chromium in the structure, this gem can vary from bluish-green in daylight to purplish-red under incandescent light. Though the discovery of alexandrite in Brazil and various other locations has expanded its availability, it still remains rarer than other gemstones, like diamonds.

Paraíba Tourmaline

Paraíba tourmaline is easily recognizable because of its brightly saturated blue/green hues. Although it was first discovered in Brazil, it has also been found in Mozambique and Nigeria in larger sizes. The gemstone is rare and pricey, because of how difficult it is to excavate. They are found in pencil-thin veins deep below the Earth’s surface in very small sizes.

The Brazilian Tanzies are off in shade compared tot he Russian ones too. It does not jump purple at me. I had a chance at one for 500 for Leahs engagement Ring once, but he would not trade even 5x for opal. He spotted it in a chrysoberyl parcel & cut it himself. it was a several thousand dollar stone. High grading dealers stock is a fine art; unlike reselling a stolen claim, which is a crime. I am so glad the criminal left Virgin Valley but it is a crime he deleted all the content he ever posted to hurt us on the way out to abuse others.
