What does luster on a diamond look like?

Luster on a diamond appears as a bright, reflective quality that gives the diamond a shiny and sparkling appearance. It is a result of the diamond's ability to reflect light due to its superior optical properties, such as high refractive index and dispersion.

Is a real diamond more or less valuable than a synthetic diamond?

A real diamond is generally more valuable than a synthetic diamond due to its rarity and natural creation process. Real diamonds are formed deep within the Earth's mantle over millions of years, while synthetic diamonds are created in a controlled laboratory setting. These differences in origin and scarcity contribute to the higher value of natural diamonds.

What is the clarity of the material?

The clarity of the material refers to how easily it can be understood or interpreted. It depends on factors such as the organization of the content, language used, and overall presentation. A clear material should convey information effectively to the intended audience.

What does rsc mean in a ring?

"RSC" on the inside of a ring refers to the RS Covenant. RS Covenant is a maker of fine jewelry, and they stamp their products with their initials.

What is the smallest size of a diamond?

As raw stones, a diamond can be as small as a grain of sand. As a cut stone, 1/100th of a carat, or .01 carat, also called one point is the smallest descriptive value found in a brief search.

Can diamond crack?

Yes, a stone can crack along a flaw in its crystalline structure. ("In the crystal structure of diamond, each carbon atom is linked to four other, equidistant, carbon atoms" from Answers.com - Diamonds.)

If a stone has been cut and polished, and the substantive flaw hidden by some enhancement or other, it's possible that the diamond could crack and split. Usually stones with flaws of this severity are not desirable. A certified gemologist can evaluate a diamond before you purchase it to identify any such flaws.

What is the base of diamond?

The base of diamond is carbon.

Does the diamond have a cleavage or fracture?

Diamond stone, because of its lattice structure of carbon atoms, is identified as an 'octahedral; perfect and easy' cleavage (according to Wikipedia).

What is a description of the diamond?

Diamond is a precious gemstone composed of carbon atoms arranged in a crystal lattice structure. It is known for its exceptional hardness, brilliance, and sparkle. Diamonds are commonly used in jewelry and industrial applications due to their durability and beauty.

Why can't we make diamonds?

We can make diamonds through a process called chemical vapor deposition, where carbon atoms are deposited onto a substrate to form a diamond. However, the natural process of diamond formation deep within the Earth's mantle involves high pressure and temperature conditions that are difficult to replicate in a laboratory setting, making it challenging to create large, high-quality diamonds efficiently.

Is diamond hard or soft?

Diamond is the hardest natural material on Earth. It is composed of carbon atoms arranged in a crystal structure that gives it exceptional hardness and durability.

Is a diamond hard or soft?

Diamond IS the HARDEST of naturally occurring materials because it is composed of extremely small atoms (carbon) packed extremely tightly where they share atoms in a type of bonding known as covalent bonding.

Termed lattice density, diamond packs atoms more tightly than any other natural material and that combined with the covalent bonding is why it is so hard.

What are some of the things that are made up of a diamond?

Diamonds are most commonly used in jewelry, such as engagement rings, necklaces, and earrings. They are also used in industrial applications, such as cutting, drilling, and grinding due to their extreme hardness. In addition, diamonds are used in some electronic devices as semiconductors due to their ability to conduct heat and electricity.

What kind of bond and structure is a diamond?

Diamond is composed of carbon atoms arranged in a tetrahedral structure bonded together by strong covalent bonds. This structure results in diamond being one of the hardest naturally occurring substances.

Where are the diamonds found?

The mineral diamond is found on earth where volcanic pipes have blasted it to the surface from where it is formed, deep within the earth's mantel. Diamonds have been found in India, Africa -- several countries -- Brazil, Canada, Australia and even in the United States.

Geologists find 'trace minerals', including kimberlite, that may indicate -- about one in 200 times -- that diamonds are included in the volcanic situation.

When water flows over the top of a diamond-producing volcanic pipe and tumbles diamond stones along, diamonds can be found in riverbeds, or at the mouths of rivers as they empty into salt water.

When a productive volcanic pipe is located, the land owner may choose to mine the area for diamonds.

Diamonds are compose primarily of which element?

Diamonds are composed primarily of carbon atoms arranged in a specific crystal lattice structure.

Is a diamond sensitive to heat?

Yes. At a little more than three thousand degrees Celsius, a diamond will actually melt.

Another Answer

The melting point of diamond is 3820 degrees Kelvin, or 6416.33 F, or 6143.18 C.

What is a dimond made of?

Coming from a ten year old, well going on eleven, and i asked this question, i think dimond is made out of rock, but i know that is is dug up and has something to do with pressure, it might be lava, my hypothysis is based on the knowledge from my fith grade teacher

it is actually made of carbon.

How much force is required to make coal into diamonds?

It requires significant pressure, around 725,000 pounds per square inch (psi), and temperatures of about 2,200 degrees Fahrenheit (1,200 degrees Celsius) to convert coal into diamonds through a process called high-pressure, high-temperature synthesis. This process mimics the natural conditions in the Earth's mantle where diamonds are formed.

Can a diamond be made into steel?

No, diamonds and steel are composed of different elements. Diamonds are made of carbon atoms arranged in a specific crystal structure, while steel is primarily made of iron and carbon atoms. It is not possible to convert a diamond into steel.

What is an irradiated diamond?

An irradiated diamond is a diamond that has been exposed to controlled radiation to alter its color. This process can intensify or change the diamond's color, often resulting in hues like green, blue, or yellow. The irradiation treatment is permanent and does not affect the diamond's durability or structure.

What makes a diamond shine?

The answer for their brightness is the refractive index of them. the light which inters the diamond does not come out because of total internal reflection into air whose refractive index is close to vacuum's i.e 1. hence diamonds shine a lot.

It has a lot to do with the cut. A good cut allows it to reflect light.

What is refractive index of diamond?

The (very high) refractive index of diamond is 2.4 at room temperature.

(From Wikipedia: "Refractive index also describes the quantity that light is bent as it passes through a single substance."

Why are diamonds wrapped in paper?

Loose stones are stored, categorized and secured in white parcel paper, sometimes with a waxed and non-waxed side.

The paper is folded with the non-waxed side out, using folds so that the loose stones don't fall out of the folded paper 'envelopes'.

The non-waxed side also affords a surface upon which to describe or code the diamond enclosed in the wrapper for inventory purposes.

What is diamonds specific gravity?

The specific gravity of a diamond typically ranges from 3.5 to 3.53. This means that a diamond is approximately 3.5 times denser than water.
