Carat:

Rare Earth metals

Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200 milligrams. Each carat can be subdivided into 100 'points.' This allows very precise measurements to the hundredth decimal place.

There are 17 elements that are considered to be rare earth elements—15 elements in the lanthanide series and two additional elements that share similar chemical properties. They are found in group 3 of the periodic table, and the 6th and 7th periods

Lanthanum

Cerium

Praseodymium

Neodymium

Promethium

Samarium

Europium

Gadolinium

Terbium

Dysprosium

Holmium

Erbium

Thulium

Composition of a Diamond

Where are Diamonds mined?

Physical Properties of a Diamond

Diamonds are pure carbon, the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice.

Characteristics of platinum

The ten largest diamond mines in the world by measurable reserves contain more than one billion carats of recoverable diamonds. Russia is home to half of the world's biggest diamond mines, while Botswana houses two; including the world's largest diamond producing mine Orapa. They dig up certain places km down the core of the planet.

Chemical Classification: native element

Mohs Hardness: 10 - the hardest mineral

Specific Gravity: 3.5 to 3.6

Diagnostic Properties: hardness, heat conductivity, crystal form, index of refraction, dispersion

Platinum is a precious metal; soft, silvery-white, and dense with a beautiful lustrous sheen. It is malleable and ductile and has a high melting point. Platinum does not oxidize in air even at high temperatures and is unaffected by common acids.

How are Diamonds formed

Don't be fooled by the rocks that I've got

Diamonds are formed deep within the Earth about 100 miles or so below the surface in the upper mantle. There's a lot of pressure, the weight of the overlying rock bearing down, so that combination of high temperature and high pressure is what's necessary to grow diamond crystals in the Earth.

How non Natural diamonds are produced

Non natural diamonds produced in an artificial process, as opposed to natural diamonds, which are created by geological processes. Some of the Non natural diamonds are made in various colors grown by the high-pressure high-temperature technique.

How are fake diamonds distinguished from real diamonds

Use a jeweler's loupe to inspect the diamond. You can usually borrow one from the jewelry store. Mined diamonds usually have small naturally occurring imperfections, which are called "inclusions," that can be seen with a loupe.

Look at the stone's refractivity. Diamonds sharply bend, or refract, the light that passes through them, resulting in their strikingly brilliant appearance. Stones like glass and quartz sparkle less because they have a lower refractive index.

Observe the reflections. A real diamond's reflections usually show up in various shades of gray. Look straight down through the top of the diamond. If you see rainbow reflections, you're either dealing with a low-quality diamond or a fake.

Structure of diamonds and other crystals

Diamond has a giant molecular structure. Each carbon atom is covalently bonded to four other carbon atoms. A lot of energy is needed to separate the atoms in diamond. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice.
