5 Mln World Record Gold Crystal Verified
All gemstones are rare; some are just harder to find than others.
In fact, there is no consensus on what is the rarest mineral or the rarest gemstone because there is no consensus on the definition of "rarity," according to the Gemological Institute of America.

Opal is Australia’s national gemstone, and black opal is the rarest and most valuable of its kind, at times selling at prices that rival the best diamonds. The stone must have a rich, black background, but base colors come in all shades of gray, which is why opinions vary on what is a "true" black opal. a particular [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] gem on our research examination [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] ‘want list.’"
A very close relative of another hard to find gemstone, taaffeite (and often misidentified as such), musgravite was first discovered in 1967 in the Musgrave Range of South Australia.
Facet grade the baseline measurement of how clean [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] cut a sellable stone must be for musgravite was not reported until 1993. For decades, only two crystals were known to exist.
It didn’t obtain official gemstone status until 1957 when the British Museum conducted X ray analysis on a sample. In 1979, a third crystal was recovered by the GIA.
Today, more than a thousand crystals and crystal fragments have been found. However, only a small percentage of the rough are suitable for sale.
Painite is made up of aluminium, calcium, boron, zirconium and oxygen. It was discovered in the late 19th century and named after Pavel V. Jeremejev, a Russian mineralogist [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] and engineer.
Until recently, the only two known localities for jeremejevite were Mt. Soktuj in the Transbaikal region of Russia and Cape Cross, Swakopmund, Namibia.
Not much is known about jeremejevite. However, the brilliant red color in these diamonds is formed from a structural defect in the crystal lattice structure, which is why they are the rarest of the colored diamond collection.
Only a handful have ever received the grade of "Fancy Red," meaning that they are pure red with no modifying color. Most are sold at market for millions of dollars.

Made popular by jewerly giant tiffany Co. in 1968, Tanzanite has seen wild price fluctuations over the years. Tanzania’s violent political, social and economic conditions have made it difficult at times to mine the mineral.
The brilliant red purple color is not a trick of the light. The stone’s actual chemistry is distinctive and separate from other beryls. It is found along fractures in topaz rhyolites. The gem crystallizes when rhyolite derived gases, vapors from heated groundwater, and preexisting minerals and volcanic glass in the rhyolite react all at once.
It was discovered as a few tiny crystals during the mid 1960s, but wasn’t recognized as a new mineral until 1986. The first ********ed gem quality specimen of poudretteite wasn’t discovered until 2000, when it was found in Mogok, Burma.
An intricately folded gold nugget turned out to be the largest individual crystal of gold ever found. Earlier this month, scientists at Los Alamos National Laboratory verified that the 7.68 ounce (217.78 gram) lump about the weight of a large onion is a single, intact gold crystal. With that crystalline pedigree, the value of the nugget rocketed in value from $10,000 to $1.5 million.
