Diamonds

A diamond is a superior conductor of thermal energy (heat). It's better at this than anything else we know of. But diamond is a poor conductor of electricity. It's actually a pretty good insulator.

Take your setting to a jeweler or a gemologist who can help you understand the nature of the stone set in silver.

At home, you can perform a small test. You can find a disposable piece of glass and drag the stone across it. If the stone leaves a groove, it's possible that the stone is a diamond, but it might not be.

Diamonds are much harder than glass, so when a diamond comes into contact with glass, the hardness and strength of the diamond prevent it from shattering the glass. Instead, the diamond would typically scratch or chip the glass surface.

The phrase "carat TW" means the carat total weight. This implies there may be multiple diamonds involved in the piece of jewelry and when they are all added together, one-tenth of a carat is their combined weight.

"Carat" is just a diamond industry special word for weight of a diamond stone. One carat is equal to 200 milligrams, or in other words, a 5-carat stone weighs 1 gram. The word "carat" originates from the Greek word kerátion, which means carob beans, which were known in the ancient world for uniformity of their size and weight and were used as a measure of weight for different objects, including gemstones.

In the Far East instead of carob beans jewelers used rice grains to determine the weight of gemstones. Because of this fact, you may occasionally hear some jewelers referring to a 1-carat diamond a "four grainer," which means in the past 1 carat was equal to four grains of rice. The weight of smaller diamonds is often expressed as points, not carats. One carat is equal to 100 points. Thus, for example, a 10-point diamond has the weight of 0.1 carats.

Yes.

Diamonds can be considered investments, especially stones larger than one carat. Moissanite stones are more commonly worn for their 'flash' value.

No, diamonds do not degrade over time. They are one of the hardest naturally occurring substances and are very resistant to wear, making them a durable option for jewelry.

Diamonds are not poisonous, though an allergy has been reported by some unfortunates.

In the diamond, you'll find only carbon. This assumes that the diamond is the only stone in the ring.

In the band and setting, you might find any type or quality of metal: gold, platinum, silver and so forth.

One way to determine whether or not a diamond is a real diamond is to use an electric probe, because a diamond will respond to electricity differently than will a fake stone.

However, diamonds are not a practical conductor of electricity: they are too expensive.

A small diamond typically refers to a diamond that is under 0.50 carats in weight. These diamonds are often more affordable and can be set in various jewelry pieces such as earrings, pendants, or delicate rings.

A diamond conducts heat, so you use a probe that confirms that the stone you're evaluating indeed meets this criteria.
Um.... Actually, I think you may want to check the rocks and minerals section? If you mean "How can you tell if your copy of Pokemon Diamond is real", then it's simple. Look it up on youtube, and you'll get very good answers.

Diamonds do not have pore space like other materials. They are composed of a compact crystalline structure with very low porosity, which means they do not have open spaces or pores within the structure.

Yes, real diamonds are heavy for their size. Diamonds have a high density, which contributes to their weight. This density is one of the factors used to distinguish between real and synthetic diamonds.

24 karat gold is 100% pure gold. There is no such thing as 28 karat gold.

People value diamonds based on their visually engaging beauty, their emotional baggage, and their investment value.

Diamonds are rare and expensive, especially larger, high-quality stones, because they are expensive to discover, mine, cut, polish and market.

Kimberlite pipes form when magma rises from deep within the Earth's mantle and rapidly reaches the surface, carrying diamonds and other minerals with it. The extreme pressure and temperature inside the mantle crystalize carbon atoms into diamonds within the kimberlite magma. When the kimberlite erupts onto the surface, it brings diamonds along, creating diamond deposits.

it is the hardest substance there is so it is used in applications where you need to drill grind or boar through some thing for instance they mine salt by using long chains embedded with diamonds to break off slabs of salt

First of all, it is spelled Karat. Gold purity indication, especially in the US, is in Karats.

Carat is used as a measure of weight, for diamonds & gemstones, where 1 carat = 200 milligrams (5 carats=1 gram).

Karat refers to part of gold present per 24, where 24 is 100%.

So if you have 18k, it means 18/24 = 75% pure gold.

22k = 22/24 = 91.66%

The balance of 8.44% usually contains mainly Copper & Silver. Other metals in small quantities , which may or not be present are usually Zinc, cadmium, indium, irridium (since it is not affected by Nitric Acid, Irridium is used to cheat people in terms of purity).

Various other metals may be added to achieve required properties like ductility, malleability, hardness, toughness, colour shades, etc.

The hardness of a diamond is measured using the Mohs scale of mineral hardness, which ranges from 1 (softest) to 10 (hardest). Diamond is the hardest naturally occurring substance and is rated at a 10 on the Mohs scale. To determine the hardness of a material, a sample of known hardness is used to scratch the surface of the material in question; if the material is scratched, it has a lower hardness rating than the sample.

Diamonds are formed deep within the Earth's mantle under high pressure and temperature. They are the hardest natural substance known, ranking 10 on the Mohs scale of mineral hardness. Diamonds are commonly used in jewelry due to their brilliance, clarity, and durability.

Diamonds are the hardest mineral known. However, a flaw in a stone presents a weak spot, and if the stone is hit 'just right', the stone may fracture along the flaw.

However, most diamonds are graded so that stones with visible flaws -- rated as Included -- (most susceptible to chipping or fracturing) are clearly identified, and would therefore be set in such a way so as to protect the stone.

22 carat refers to the purity level of gold, with 22 parts being gold out of a total of 24 parts in the alloy. This means that gold is 91.67% pure in 22 carat jewelry, making it softer and more prone to bending compared to higher purity levels.
