Do lab created diamonds last as long as real ones?
Yes, lab created diamonds have the same physical and chemical properties as natural diamonds, so they are just as durable and long-lasting. Both types of diamonds are suitable for everyday wear and can last for generations if properly cared for.
How can diamonds form at river beds?
Diamonds don't 'form' in river beds or in the sea bed where some are found. Diamonds are propelled into river beds and to the sea by water that flows over the kimberlite pipe where the diamonds are formed.
Diamonds found in water are generally referred to as alluvial stones, meaning deposited in the water over a long period.
What does grit have to do with diamonds?
"Grit" is the term used to describe the physical and chemical properties of a diamond that make it hard and durable. Diamonds are made up of carbon atoms that are arranged in a specific crystal structure, which gives them their unique hardness and ability to withstand scratches or damage. This "grittiness" is what makes diamonds ideal for use in cutting, grinding, and other industrial applications.
What is the value of an IGA certified 1 carat flawless color D brilliant cut diamond?
The value changes with market conditions, and the diamond industry's Rapaport report is updated weekly. If you are looking for the retail price (appraised value) of a diamond, plug its attributes into a diamond search engine, such as http://www.diamondpriceguru.com. When I input the given stats (1-carat, flawless, D-color, brilliant [round]) the search engine had zero results. After expanding the search to include internally flawless (IF) diamonds, 32 were found. None were IGA certified; most were GIA. They were further divided into three categories: Cut: Ideal: $12,880 to $21,553. Cut: Very Good: $14,785 to $22,582. Cut: Good: $12,650 to $25, 842.
Can diamonds be destroyed by a bullet?
If you purchased a lot of industrial diamonds -- costing about US$1.60 per pound -- and used it for target practice, you would end up with a lot of industrial diamonds in smaller pieces than the lot you started out with.
If you purchased a gem-stone diamond large enough to use for target practice, you might not be able to 'destroy' it: you might be able to split it into multiple pieces, significantly reducing its value. Or not.
What are Asscher cut diamonds?
Asscher is a cut of diamond favored if the colour and clarity are superior and the raw diamond is fairly large. Cutting and polishing a diamond loses about 60% of its carat weight. Although any size raw diamond can be cut this way.
From the Diamond Pro web site, this is a description of the Asscher cut:
"Depth is 60% to 68% -- under 65% is relatively hard to find; table is 60% to 68%, polish/ symmetry is good, very good or excellent, and the length/ width ratio is 1.00 to 1.05 according to the GIA acceptable range for defining a diamond as a square [cut]."
Yes, a diamond can scratch other materials because it is the hardest natural substance on Earth. However, this does not mean that all diamonds are equally hard as there may be variations in their quality and structure.
Why is a diamond more brilliant than a glass imitation cut the same way?
From Suite101, "Ordinary commercial glass is made from sand which is silica or silicon dioxide." Silica and silicon dioxide are more common than diamonds, and the structure of the atoms in glass is less stable and more absorbent than diamonds. (This mineral is also used in foodstuffs.)
Diamonds are made from carbon. The carbon atoms bond to form diamonds more tightly than atoms of any other mineral. This makes diamonds the hardest mineral known.
Light refracting from cut glass reflects and refracts at lesser intensities than diamond, because of the density and compactness of the carbon atoms as compared to the 'looser' silicon dioxide atoms.
Diamonds are not soluble in hexane because diamonds are composed of carbon atoms arranged in a specific crystal lattice structure that is not compatible with dissolution in hexane. Hexane is a nonpolar solvent, which cannot break down the strong covalent bonds present in diamond.
Can a diamond break from being dropped?
Diamonds are like, the worlds strongest, pricless, and valuable rocks, it takes a lot to break, unless you dropped in from.. a thousand story building?
Another Answer
A diamond can fracture along its natural lines if it's hit 'just right'. Most diamond cutters plan cuts so that a finished diamond gemstone is never subjected to angles or pressure points where this natural fracture can occur accidentally. However, diamonds can fracture along a flaw.
What color is a diamond's dust when crushed?
When a diamond is crushed into dust, it appears colorless. This is because diamonds are typically transparent and colorless in their natural state. The crushed diamond dust may appear sparkly due to its structure, but it does not display any specific color.
Do you breathe out diamonds in their gas state?
No, breathing out diamonds in their gas state is not possible. Diamonds are a solid form of carbon and cannot exist as a gas in the way that oxygen, nitrogen, or other gases do. This concept does not align with the properties of diamonds.
Diamonds are typically not melted in a traditional sense due to their extremely high melting point of around 3,500 degrees Celsius. Instead, diamonds are typically burned under high-pressure oxygen to convert them into carbon dioxide gas.
Why does glass shatter more easily than diamond?
diamonds are stronger than glass, therefore, glass shatters more easily.
Can you tell if a diamond is real by scanning it in a printer?
No, you couldn't. Printers don't scan things.
_____________
Perhaps your printer scans, in which case it could use a fluorescent bulb or a bulb that contains some other gas: in any event, it is a light source. You can see a diamond's reflective quality in response to any light source, from a candle to the sun.
This is not a typical test for a diamond. You're better advised to take your diamond to a gemologist who can test it and tell you whether or not the stone is a real diamond.
The reason diamonds looks many colored is because?
diamonds look colorful due to dispersion, which splits white light into its constituent colors. When light enters a diamond, it refracts and disperses, creating spectral colors. This dispersion is more noticeable in higher-quality diamonds with better cut and clarity.
Do black diamonds reflect light?
Black diamonds are known for their unique color and light-absorbing properties, which give them a distinctive appearance compared to traditional white diamonds. While black diamonds may not reflect light in the same way as white diamonds, they can still exhibit a beautiful luster and sparkle due to their polished surfaces and faceting. The dark color of black diamonds may create a different kind of brilliance that is more subtle and mysterious.
Is Si a good clarity for a diamond?
According to Wikipedia:
"Slightly Included category (SI) diamonds have noticeable inclusions that are easy to very easy for a trained grader to see when viewed under 10x magnification.[2] The SI category is divided into two grades; SI1 denotes a higher clarity grade than SI2. These may or may not be noticeable to the naked eye."
"Good" is relative. From an investment point of view, SI is not as good as the less included clarity ratings.
Can ashes be made in to Diamonds?
If there are enough ashes to extract enough Carbon then it is possible...please click on the link below and it will take you to the website of lifegem where they take the ashes of your loved one and convert the carbon in the ashes into a true diamond.
Are diamonds a non renewable source?
Diamonds are considered non-renewable because they take millions of years to form under specific conditions that are not easily reproducible. Once extracted from the Earth, diamonds are not naturally regenerated within a human-relevant time scale.
What is hardest naturally occurring substance?
Diamond is the hardest naturally occurring substance on Earth.
Aggregated Diamond Nanorod are the hardest overall and un-naturally occuring substance on Earth. They are actually a group of tiny diamonds which are virtually un-compressable.

Why are diamonds used in rings?
Gem-quality diamonds are valuable, beautiful and engage the eye. Setting a diamond in a ring affords a buyer a way to confirm to the wearer the authenticity of certain emotional and symbolic commitments.
What is the percent of carbon in diamond?
A diamond is 100% carbon, and the structure may also be contaminated with traces of other minerals, some of which give a diamond colour.
For example, the Hope Diamond is blue, because those crystals contain minute amounts of boron.
