More than millions of dollars for a piece of stone!
In your opinion, what are the most expensive stones in the world?
These gems are very expensive because of their rarity or appearance. These stones are found mainly in different parts of the world and just a small amount of them could turn unlucky people into wealthy happy one. In this article we will introduce you five of the most expensive and rare stones in the world.
Bahia Emerald
At the moment, “Bahia Emerald” is the largest raw uncut emeralds available in the world. This emerald consists of several main branches of the emerald, stuck in a large gem. This gem totally weighs about 1.9 million carats and its price is close to 900 million dollars. It caused this gem known as the most precious gemstone in the world. This gem found in 2001 for the first time near a mine in Brazil.
Neelanjali Ruby
Ruby is one of the most precious stones you are familiar with. Ruby, in certain conditions, accepts patterns that are like small stars. These patterns on gem will increase their value and are also very rare. “Neelanjali Ruby ” is a ruby that has two stars on its own, which is almost rare and unique in the world. After discovering it in 1988, it quickly entered the Guinness Book of Records. This gem price is about 100 million dollars, as it is very rare.
Jubilee Diamond
In 1985, near a mine in South Africa, a worker found a brown and luminous stone that weighed about 151 grams. After being evaluated, this diamond went under cutting for two years, in a safe underground, away from robbers, and then turned into the largest cut diamond in the world. The diamond was sold to Thailand for 120 million dollars.
Smithsonian Alexandrite
One of the rarest gems in the world is “Alexandrite” and it’s very hard to find. The stone was first seen in Sri Lanka and then sent to America for cutting. This gem weighs about 65 carats, known as one of the most valuable jewels in the world. This gem price is close to 100 million dollars and is recorded in the Guinness Book of Records as the largest and most expensive Alexandria.

Diamond…
Diamond is a solid form of carbon with a diamond cubic crystal structure. At room temperature and pressure it is metastable and graphite is the stable form, but diamond almost never converts to graphite. Diamond is renowned for its superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, it has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial applications of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.
Because of its extremely rigid lattice, diamond can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).
Most natural diamonds have ages between 1 billion and 3.5 billion years. Most were formed at depths of 150 to 250 kilometers (93 to 155 mi) in the Earth’s mantle, although a few have come from as deep as 800 kilometers (500 mi). Under high pressure and temperature, carbon-containing fluids dissolved minerals and replaced them with diamonds. Much more recently (tens to hundreds of million years ago), they were carried to the surface in volcanic eruptions and deposited in igneous rocks known as kimberlites and lamproites.
Diamonds can be produced synthetically in a high pressure, high temperature method (HPHT) which approximately simulates the conditions in the Earth’s mantle. An alternative, and completely different growth technique is chemical vapor deposition (CVD). Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been developed to distinguish natural diamonds, synthetic diamonds, and diamond simulants.
Ruby…
A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald, and diamond. The word ruby comes from ruby, Latin for red. The color of a ruby is due to the element chromium.
The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. The brightest and most valuable shade of red called blood-red or pigeon blood, commands a large premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Ruby is the traditional birthstone for July and is usually more pink than garnet, although some hodolite garnets have a similar pinkish hue to most rubies. The world’s most valuable ruby is the Sunrise Ruby.
Emerald…
Emerald is a precious gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included,[3] so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate.
Emeralds, like all colored gemstones, are graded using four basic parameters–the four Cs of connoisseurship: color, clarity, cut and carat weight. Normally, in the grading of colored gemstones, color is by far the most important criterion. However, in the grading of emeralds, clarity is considered a close second. A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency to be considered a top gem.
In the 1960s, the American jewelry industry changed the definition of emerald to include the green vanadium-bearing beryl. As a result, vanadium emeralds purchased as emeralds in the United States are not recognized as such in the UK and Europe. In America, the distinction between traditional emeralds and the new vanadium kind is often reflected in the use of terms such as “Colombian emerald”.
Diamond trading centers…
Antwerp (in Dutch : Antwerpen ) (in French : Anvers ) is a city in Belgium and the size of the city and suburbs of Brussels ‘s second largest city and the urban unit is the largest city in the country.
This city is the capital of Antwerp and also the most populous city in the Flanders area . According to the latest figures, the population of Antwerp in 2014 was 510,610.
The city of Antwerp is located on the right bank of the Escaldes , and has long been one of Benelux’s most important cultural and economic centers . It is also home to Belgium’s economic activities. Port Antwerp is one of the largest ports in the world. This is the second largest port in Europe and one of the major transportation and trade centers on the continent. The port also has the largest collection of petrochemicals in Europe.
Background
Antwerp’s history dates back to a small village that made the Romans and flowers . In explorations conducted in the Scheldt region from 1952 to 1961, parasfals and fragments from the middle of the second century until the end of the third century AD were found.
Name of the city of Antwerp for the first time in the fourth century AD as a Germanic tribe settlements Frank mentioned. The city’s name is said to be derived from the words “anda” (aside) and “werpum” (the pier). Another story is “an der Warft”, which means “beside the harbor.
Economic importance
Port Antwerp, as the second largest port in Europe, plays a major role in the trade and transportation of this continent. The logistics position of this port has brought together numerous shipping and trading companies. The largest integrated petrochemical complex in Europe is located in the same port. The collection includes five refineries, Europe’s largest petroleum depository, as well as a major center for most of the world’s largest petrochemical companies, including BASF. Seven of the top ten petrochemical companies operate in Antwerp. This diversity and breadth of services in Antwerp has made this city one of the most important economic and commercial bases in the continent of Europe.
At present, the Antwerp port, with an equivalent of 8.5 TEU, is the most important gateway to Europe. By the end of 2015, the volume of oil shipment by this year grew by 2.7% compared to the same period last year. Also, container shipments increased to 4.4 million TEUs, up 2.9 percent. In addition, in 2015, the total volume of oil transported in this port reached 30.42 million tons, which has grown by 4%
