Gemstone

 Gemstone

A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks and occasionally organic materials that are not minerals are also used for jewelry and are therefore often considered to be gemstones as well.

 

The twelve sacred gemstones of Revelations are Jasper, Sapphire, Chalcedony, Emerald, Sardonyx, Sardius, Chrysolite, Beryl, Topaz, Chrysoprasus, Jacinth, and Amethyst. Many also believe that there is a clear association between the twelve apostles and the twelve gems from the walls of Jerusalem.

 

Rose Quartz: Known as “the stone of unconditional love,” rose quartz opens the heart, inspiring self-love while attracting or renewing romantic love.

 

List of the Most Rare Gemstones in The World

 

    Benitoite.

    Grandidierite.

    Red Beryl.

    Jadeite.

    Black Opal.

    Taaffeite.

    Alexandrite.

    Painite. The Guinness Book of World Record called Painite the world's rarest mineral.

 

Gemstone pricing and value are governed by factors and characteristics in the quality of the stone. These characteristics include clarity, rarity, freedom from defects, the beauty of the stone, as well as the demand for such stones. There are different pricing influencers for both colored gemstones, and for diamonds. The pricing on colored stones is determined by market supply-and-demand, but diamonds are more intricate. Diamond value can change based on location, time, and on the evaluations of diamond vendors

 

Each laboratory has its own methodology to evaluate gemstones. A stone can be called "pink" by one lab while another lab calls it "padparadscha". One lab can conclude a stone is untreated, while another lab might conclude that it is heat-treated. To minimize such differences, seven of the most respected labs, AGTA-GTL (New York), CISGEM (Milano), GAAJ-ZENHOKYO (Tokyo), GIA (Carlsbad), GIT (Bangkok), Gübelin (Lucerne) and SSEF (Basel), have established the Laboratory Manual Harmonisation Committee (LMHC), for the standardization of wording reports, promotion of certain analytical methods and interpretation of results.

Radiology is the medical discipline that uses medical imaging to diagnose and treat diseases within the bodies of animals, including humans. Radiologists are medical doctors that specialize in diagnosing and treating injuries and diseases using medical imaging (radiology) procedures (exams/tests) such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET) and ultrasound. a radiologist completes about 13 years of training after high school. In addition to this training, there are two exams to successfully take to become certified by the American Board of Radiology. Some subspecialties of radiology must be chosen during the residency period. Becoming a radiologist can be a very rewarding career. A day in the life of a radiologist may include all of the tasks above, which could be specialized into a specific area of radiology. If you're considering entering this career field, it may be a good idea to understand the tasks of the job first. The required education for a radiologist includes a four-year college degree, medical or osteopathic school and at least four years of residency training. In addition, all radiologists must fulfill the examination requirements for state licensing. Essential skills Attention to detail. Ability to work as an individual and as part of a medical team of specialists. Excellent communication skills. Able to work well in stressful conditions. Critical thinking. Extensive knowledge of and an aptitude for the medical profession.

 Quantum_mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.   science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.   counter-intuitive phenomenon predicted by quantum mechanics is quantum tunnelling: a particle that goes up against a potential barrier can cross it, even if its kinetic energy is smaller than the maximum of the potential.[7] In classical mechanics this particle would be trapped. Quantum tunnelling has several important consequences, enabling radioactive decay, nuclear fusion in stars, and applicat

Energy

 Energy in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.   For the potential energy the formula is P.E. = mgh   The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.   The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.   Wasted energy is energy that is not usefully transferred or transformed. Energy cannot be made or destroyed. ... The energy that is not used in this process is wasted energy. For example lighting a light bulb uses electrical energy to make light energy which is useful.   While energy can come in many different types, there are onl
