Pearl types

Natural pearls. The Persian Gulf, near the State of Bahrain, and even forties of the twentieth century the main place to find the pearl oysters. Located other citizen of the natural pearl oyster in the

South Pacific. Must collect thousands of oysters to get a small amount of pearls. For this reason the cost will be high pearl. Brings little natural pearls for use in jewelery, currently, because the cultivation of pearls cultured pearls produces less value.


Natural pearls from the Persian Gulf near Bahrain, a high value compared to cultured pearls. The ornaments are made from high-end contracts. Almsahnh used to grind Shti of pearls, which can not be sold to its small size, and therapeutic purposes.

Cultured pearls. Pearl is real, is made from shellfish and can not be distinguished from the natural pearls, but examinations conducted in the laboratory.

The central body which adopted around classes in cultured pearls is larger than it is in the natural pearls. The cultured pearl layers fewer but thicker, and the greater the thickness of the layers has increased the value of the pearl.

Cultured pearls produced for the first time enter the bead made of pearls or nacre secreted by certain types of clams and oysters is edible, the conch. See: or pearls.

Attaches mediated Wood Ring, and descend in a quiet water on the side of the beach is protected.

Officials lifted the cages twice a year, and removing oysters kelp and some marine animals that are attached. Oyster growth records and care that offers him the cards installed on the metal cages.

What is uranium

Uranium metal, high-density, and density close to almost gold density, but one atom of uranium mass is much larger than the mass of the gold atom, and

thus the uranium metal is a metal atoms are more metal atoms by weight and most block, and it is not the highest density , as the higher mineral density is osmium (where the density is higher compaction Supreme block inside the unit size and osmium are higher than in uranium).

Uranium metal is the most common metal in nuclear tests in the laboratory, it is natural corn most candidates, nuclear fission and formation of other elements and liberalization of the energy, the atomic number (number of protons) of an atom of uranium is 92, and enriched his six matches in nature are all equal, of course in and atomic number is 92, but they are different in the mass number, Venzaúr uranium known are:

Uranium 232

Uranium 233

Uranium 234

Uranium 235

Uranium 236

Uranium 238

Where the number after the name refers to the weight mass and weight reflect the total mass of protons and neutrons in the nucleus, if the fixed number of protons (the number of protons that determines the identity of corn), the difference is in the number of neutrons in the previous isotopes are respectively as follows (your subtracting 92 from the mass number to get them): 140 141 142, 143 144 146.

And uranium found in nature as the isotope: the highest proportion of uranium 238 isotope, as this constitutes 97% of the amount of uranium found in nature.

The uranium metal component of this radioactivity in the sense that it is stable and its atoms disintegrate Trigaa to be the atoms of other elements and release energy as a result, and this is what scientists to study urged to take advantage of those characteristic of him and is the susceptibility of nuclear fission and energy that could benefit mankind greatly launch .
