按照这个网站http://www.therichest.com/luxury/most-expensive/the-top-ten-most-expensive-gemstones-in-the-world/
的说法,钻石似乎不是最贵的。

1. Jadeite – more than $3 million per carat


This gemstone is actually a pyroxene mineral, usually of apple green, emerald green, bluish green or leek green in color. There have also been some that are either greenish white or white with some green spots. Jadeites are colorless in the thin section of the stone. The more intense the green, the more expensive the stone will get. The Chinese, however, also value the white jadeite with green spots. A deep blue-green jadeite that emits a translucent hue has also been discovered in recent times in Guatemala. While it is considered valuable because of historical reasons as the Mesoamerican Olmec used it, the rarity of this specific kind of jadeite has yet to be established. Once the Guatemalans start actively mining for it and confirms its rarity, the value may increase even more.

2. Red Diamonds – $2 million to 2.5 million per carat


This gemstone is very rare. Most of it are actually purplish red, and not crimson or pure red. A mining company located in Australia gets to find only a small number of red diamonds every year. These are then sold at an auction once every couple of years, and you can just imagine the interest, demand and price that the red diamonds command.

3. Serendibite – $1.8 million to 2 million per carat


The serendibite gemstone is an extremely rare mineral that bears boron. Only two areas have been known to produce quality serendibite, namely Ratanapura in Sri Lanka and Mogok in northern Burma. Most of the serendibites found are blue green, grayish blue or pale yellow with a white streak.

4. Blue Garnet – $1.5 million per carat


There are many kinds of garnet in the market. You can find it in a variety of colors, from black, brown, green, orange, pink, purple, red and yellow. There have even been some that do not have any color. But none can compare to the price of the blue garnet. This gemstone was discovered in Madagascar in the 1990s, though it has since been mined in Russia, the United States and Turkey as well. While it has a blue green shade, the generous amount of vanadium in the stone makes it emit a purplish hue when it is held against incandescent lighting.

5.Grandidierite – $100,000 per carat


Alfred Grandidier was a natural historian famed in the archaeology world for his discovery in Madagascar of the skeletons and remains of an elephant bird that weighed half a ton and that has been extinct for thousands of years. He is also famous in the world of gemology for discovering in Sri Lanka a rare stone that transmits blue, green and white light. Initially, they thought it was the gemstone serendibite, but after closer scrutiny, gemologists concluded that it was a totally new stone. It was thereafter named after Grandidier.

6. Painite – $50,000 – 60,000 per carat


Discovered in the 1950s by the Englishman Arthur C. Pain, painite is a rare borate material. It has a natural hexagon shape and has an orange-red or brownish-red color. Trace amounts of iron, vanadium and chromium are present in the stone. While it used to be the rarest stone in the world, more have been unearthed and discovered in Burma recently.

7. Musgravite – $35,000 per carat


This gemstone is actually a silicate mineral that was first discovered in Australia in an area called Musgrave. While similar minerals have since been unearthed in Madagascar, Greenland and Sri Lanka, it is still considered very rare. There are trace amounts of aluminum, berrylium and magnesium present in the stone.

8. Bixbite – $10,000 per carat


This gemstone is also known as the red beryl emerald. It is very rare and has been found only in a couple of places in Utah called Juab County and Beaver County, and in Sierra County in New Mexico. Most of the red beryl that are gem-grade can be found in Violet Claim. This is located in the Wah Wah Mountains of midwest Utah. A Filmore, Utah local named Lamar Hodges discovered the bixbites by accident. He was a mineral prospector who was actually looking for uranium when he stumbled upon the red beryls.

9. Black Opal – $2,355 per carat


Opal is the national gemstone of Australia, which produces 97 percent of the world’s supply. The southern portion of the country alone produces 80 percent of all opals. Opal is not a mineral, as it is actually an amorphous form of silica that is related to quartz. Up to 20 percent of the stone’s weight is made up of water. The internal structure of this gemstone makes it diffract light, and it may come in a variety of colors ranging from blue, brown, gray, green, magenta, olive, orange, pink, red, rose, slate, white and yellow. But the most rare and most expensive are the black opals. The stone has also been unearthed in Brazil, Mexico, the United States, Mali and Ethiopia.

10. Jeremejevite – $2000 per carat


This gemstone is actually made of aluminum borate mineral with fluoride and hydroxide ions. Pavel Vladimirovich Eremeev discovered it in Siberia. Most of this stone are colored blue or yellow. White and colorless versions of this gem have also been discovered. Jeremejevite has since been unearthed in other areas as well, notably in Namibia, the Eifel District in Germany and the Pamir Mountain area in Tajikistan.

最贵的居然是宝石级的翡翠,为什么?翡翠应该算玉石吧。到达宝石级难道不是硬度(已到达),透明度和稀有度达到一定程度吗?感觉提升一下透明度就到达了的样子。。。。。。。。至于文中所说的的绿色的深浅,小白想说翡翠多数不都是绿的吗,差别会很大?为什么它会稀有呢?@橡树村

如果有人去过世界上宝石级翡翠的几乎唯一产地缅甸,出产闻名遐迩的中国翡翠,去看看真正的翡翠,就知道那美得震撼和价格的惊人了。
以翡翠的稀有程度,还真不是那些宝石能相提并论的。我国领土上未能占有中国翡翠的出产地,划给缅甸,但是中国获得了长达70年(好像是)开采权,结果就是,现在矿脉几近枯竭了,如果宝贝不在你家,你有什么理由不暴力开采。
在云南看到那些动辄成百上千万的翡翠被出售,虽说有热炒的嫌疑,不过绝版的稀世珍宝就是绝版,美就是美。

翡翠的颜色问题,现在的翡翠,已经有了几乎所有颜色,不要惊讶,赤橙黄绿青蓝紫粉,统统都有,人印象当中的苍翠欲滴的翡翠,的确是上上之品,但是因为矿脉的问题和翡翠本身特性,初期是上等品是苍翠鲜亮,后来什么颜色都有了,包括墨翠(漆黑),紫罗兰,金丝种,透明的等等。品相好坏不单以颜色论,水头、冰种很多讲究。大致就是越水灵越动人的越好,颜色或纯净或浓郁或糅合有质,都可以成为上品。不过随着影视作品和人们的观念,传说中的翡翠,就是那苍翠欲滴(价值连城)的感觉啊!

话说珠宝店里能见到的,都不知道是不是翡翠。估计能是个B货就很满足了。

在怎么稀有的东西,无非也是石头,好看一点的石头,稀有未必就代表有价值,当然人类总是喜欢将所谓价值扣在某些看起来稀有的物品,其实这些东西并没有实际意义,在我看来这个世界最有价值的就是生命,离开了生命,一切都没有意义,因此一切以保障、提高生命健康、长寿的物品才是最有意义的,最有价值的
