Alexandrite is originally from Russia’s Ural Mountains. The gemstone can also be found in Brazil, India, Madagascar and Sri Lanka. Anything over 3 carats is very rare. The story of its origin is controversial, but it is said to be discovered by a Finnish mineralogist by the name of Nils Gustaf Nordenskiold in the 1800’s and named after Tsar Alexander II of Russia.
California’s state gem has only been found near the San Benito River in San Benito County. Benitoite is rumored to have also been found in Japan and Arkansas, but those stones were very limited in number and not of good quality.

The color can range from a light olive green to a dark greenish blue and a light shade of violet to a darker purple.
Named the world’s rarest gemstone mineral by the Guinness Book of World Records in 2005, Painite was originally discovered by a British mineralogist named Arthur C.D. Pain in Myanmar in the 1950’s. This hexagon shaped mineral was so rare that until 2005, there were only two known Painite crystals on earth. In 2005, it was discovered that there were still less than 25 known Painite stones. They have an orange-red to brownish-red tone and look similar to topaz.
More recently, the actual source of the original stones were discovered in Myanmar with two new major locations containing the stone in Magok. This discovery has led to finding thousands of fragments of the stone, although it still remains on the list of the rarest minerals on the earth. Up until 2004, only two crystals had been cut from their original hexagon shape into faceted gemstones.

There are about 8000 times more rubies than these unusual stones. They are found mostly in the Wah Wah Mountains, Beaver County, Utah and in Paramount Canyon and Round Mountains, Sierra County, New Mexico. In 1958, Lamar Hodges of Fillmore, Utah came across red beryl while he was on the hunt for uranium.
Red beryl is sometimes confused with pezzottaite, which is known as raspberyl, and is found in Madagascar and Afghanistan. The stone is associated with bixbyte, quartz, topaz and hematite. The cost of a cut red beryl stone is at least $10,000 per carat.

It is a bluish/purple color, but can appear blue, violet and burgundy depending on its crystal orientation. The stone will appear bluer when seen in fluorescent lighting and a violet color when seen in incandescent lighting.
The first tanzanite was found in the Meserani Hills of Manyara Region in the northern part of Tanzania in the mid to late 1960’s. This region is near the city of Arusha and Mount Kilimanjaro. Before it is cut, tanzanite will appear a reddish brown color. The heat of a gemological oven is required to allow the blue and violet color to appear. It is a relatively softer stone, so most jewelers prefer to set it in necklaces and earrings, rather than rings and bracelets.
