Most Frequently Asked Questions About Diamonds


The first step in purchasing the best diamond is to ask the appropriate questions. You'll be able to handle the diamond buying experience like a pro once you check out the questions & answers below.


Q: What is a diamond?

A: A diamond is a carbon crystal that is the hardest naturally occurring substance. It is formed deep in the earth under intense heat and pressure.


Q: What does diamond clarity mean?

A: Diamond clarity refers to the number and size of the blemishes or inclusions on the surface of the diamond, as well as the internal imperfections. The fewer and smaller the blemishes, the higher the clarity grade.


Q: Which diamond clarity is best?

A:The highest grade of a diamond on the diamond clarity scale is FL, or flawless. Even if viewed under 10x magnification, the GIA only classifies a stone as flawless when a skilled grader detects no impurities or diamond flaws. Hence, Fl or flawless is the best diamond clarity grade.


Q: What is the difference between colorless and near-colorless diamonds?

A: Colorless diamonds are entirely free of any hue, while near-colorless diamonds have a faint yellow or brown tint.


Q: What does carat mean in diamonds?

A: Carats are an international standard unit of measurement for diamond weight. A one-carat diamond equals 200 milligrams, so a 5 carat diamond will weigh one gram. The carat of a diamond, contrary to popular belief, refers not to size but to the diamond weight.


Q: How are diamond carats measured?

A: A diamond's carat weight refers to the stone's weight; a one-carat diamond is approximately 200 milligrams. Diamonds with less than one carat are equal to one-hundredth of a carat (0.01 carat, or 2 mg). The diamond cost per carat is directly related to the carat weight. The heavier the diamond stone, the higher the diamond cost will be.


Q: What are the four cs of a diamond? How are diamonds graded?

A: The four Cs of a diamond stone — cut, color, clarity, and carat — are the four qualities that determine a diamond's quality and price. These are the standards utilized by independent gemological institutions to grade diamonds.


Q: Which diamond cut sparkles the most?

A: The most beautiful sparkling diamond cut is the brilliant round cut. Brilliant cut diamonds have 58 facets (including the culet), allowing for peak light performance to enter the stone and sparkle across all of them.

Interestingly, the brilliant round cut was actually designed and engineered specifically to have the strongest possible sparkle.


Q: Are diamond accents real diamonds?

A: Diamond accents are only slightly different from larger diamonds. Diamond accents are not faux diamonds because they have the same carat grade, color, cut, and clarity as other real diamonds.

Individual accent stones are less valuable because of their smaller size, but the value of accent stones is the same as that of a larger, real diamond when combined.


Q: Which diamond shape looks biggest?

A: The round cut (and Old European cut) has the biggest look out of all diamond cuts. It's no accident that it's the most popular and costly type of diamond on the market.

A round-cut diamond gives the impression of a 0.5x larger stone.


Q: How can I make my diamond look bigger?

A: The best way to make your diamond stone appear larger is to choose a setting with less metal around the band. A bezel setting will also make your diamond stand out more.


Q: What is a good quality diamond?

A: A good quality diamond should be "eye clean," meaning that no inclusions or blemishes are visible to the naked eye. It should also have a high color grade (D-F) and clarity grade (IF-VVS2). The cut of the diamond is also important, and a well-cut diamond will have good symmetry and proportions.


Q: Which diamond cut is the most expensive?

A: Not only is a round cut diamond the most expensive diamond shape to manufacture, but it's also the most in-demand stone shape out of all the different diamond cuts. Nearly 75% of all diamonds sold worldwide are round-cut diamonds.


Q: Which of the 4cs is most important?

A: The cut of a diamond is the most essential out of the 4cs of diamonds. Color, clarity, and carat weight are next in importance.


Q: What does clarity-enhanced diamonds mean?

A. A clarity diamond undergoes enhancement in the form of various diamond treatments such as laser drilling and fracture filling to remove unsightly flaws, surface blemishes, and inclusions from high inclusion diamonds. You may think of the technique as “cosmetic surgery” on heavy inclusion diamonds to disguise or minimize diamond flaws.


Q: How long do clarity-enhanced diamonds last?

A: Enhanced diamonds are not imitation diamonds. Natural diamonds that have undergone color improvement treatments are known as enhanced diamonds. Diamond treatments are typically permanent and do not alter the diamond’s chemical structure; hence enhanced diamonds are not imitation diamonds.


Q: Are clarity-enhanced diamonds good?

A: Clarity-enhanced diamonds are cost-effective for purchasing a greater carat weight without breaking the bank.

All diamonds that have any treatments or enhancements applied to them, like clarity-enhanced diamonds, should be disclosed and sold as treated diamonds. Jewelers cannot falsely represent a diamond stone as natural if it undergoes any diamond enhancements such as clarity or color treatments.


Q: Do enhanced diamonds look different than naturally mined diamonds?

Some people point out that clarity-enhanced diamonds have a “glow” different from naturally mined diamonds. Others say clarity-enhanced diamonds are simply more brilliant.


Q: What are diamond facets?

A: Diamonds have numerous facets on their surfaces, and the angles of the cuts control how exquisite the light performance is, a.k.a; how much light penetrates or exits the stone. A diamond has three components: the crown, which is on top, the girdle, which holds the gem setting in place, and the pavilion, which houses the diamond culet. The most popular diamond cut has 58 facets, with the pavilion and crown having the greatest impact on the light show we observe when examining a diamond.


Q: What Are the Types of Diamond Facets?

A: The table facet, star facets, main facets, and break facets make up the crown of a diamond.


Q: What are the different diamond colors?

A: Naturally occurring diamond colors include gray, white, blue, yellow, orange, red, green, olive, pink, purple, brown, and black.


Q: Which diamond color is the best?

A: The D grade is the purest diamond color grade a stone can have, and it may reasonably be called the “best color” for a diamond.


Q: What does colorless diamond mean?

A: Diamonds without a light yellow or brown tint caused by boron and nitrogen are colorless diamonds. The less yellowish colorless diamonds are, the more valuable they are. This is because diamonds with little color concentration give off the illusion of being very bright and sparkly.


Q: Which diamond is the rarest diamond?

A: Yellow is the most common diamond color, and red is the rarest diamond color out of all fancy colored diamonds. Fancy-colored diamonds account for less than 0.1% of the total diamonds mined worldwide. These gems are incredibly uncommon. There are certain hues among fancy colored diamonds that are so rare that they are sold before reaching the processing facility.

Red is the rarest diamond color. Pure red diamonds do not exist and, to date, have not been discovered. Red diamonds range from fancy purplish-red or brownish-red. When combined with superior 3C components, their crimson color makes them priceless.


Q: Are colored diamonds natural?

A: Yes, colored diamonds are naturally occurring minerals that come in several color combinations and intensities.


Q: What are colored diamonds?

A: When viewed face-up, diamonds with a significant body color are known as colored diamonds. The most prevalent colors in natural colored diamonds are brown and yellow. Diamonds with natural body colors of pink, blue, orange, green, red, or violet are scarce.

Only a few diamonds out of 100,000 will have one of the ultra-rare hues. The color’s intensity can range from “very light” to “vivid.”


Q: Are colored diamonds more expensive?

A: Colored diamonds are more valuable than white diamonds, but the difference varies greatly depending on the particular color.


Q: Are fancy yellow diamonds more expensive?

A: Although fancy yellow diamonds, a.k.a canary diamonds, are more expensive than white diamonds, they are frequently less costly than other fancy colored diamonds. This price is because canary diamonds are yellow, and this is the most common diamond color among fancy colored diamonds.


Q: Which setting makes a diamond appear bigger?

A: In a pavé setting, many pavé crystals as small as 0.20 carats line up in tapered holes on a metal panel close to the melee stones next to them. A pavé setting makes the band appear as a continuous series of pavé crystals, making the center stone look more prominent.


Q: Is cut or clarity more important in a diamond?

A: The diamond shape determines the overall look of a diamond. A poorly cut diamond stone can't benefit from a good grade on the diamond clarity scale; nevertheless, an excellent cut diamond may have a lower color (G-H) or clarity (SI1-SI2) and yet appear stunning due to its superior capacity to generate sparkle and fire.


Q: What are diamond inclusions?

A: Diamond inclusions are due to the high pressure, and high-temperature environment found deep within the earth's mantle. Various clarity features occur in and on diamond crystals under these circumstances.

Few crystals do not have any external or internal diamond flaws. These flawless diamonds have an F clarity grade.

Lab-created diamonds also have inclusions, but instead of being made of mineral crystals, these impure diamonds have metallic inclusions. These flaws are how jewelers can tell lab-grown diamonds from naturally occurring minerals.


Q: What do inclusions in diamonds look like?

A: Depending on the type of mineral crystals they are, they are sometimes colorless (this is when a diamond stone embeds itself within another diamond), black (carbon), reddish (garnets), greenish (peridots), etc. Colored crystal inclusions, on the other hand, are considerably more apparent to the naked eye, and impure diamonds are generally undesirable since they are so apparent.


Q: What does an eye-clean diamond mean?

A: An eye-clean diamond means a stone that lacks diamond impurities or surface blemishes visible to the naked eye.


Q: Do diamonds get cloudy?

A: Yes, diamonds get cloudy. They usually are perfectly transparent, brilliant, and sparkly, but sometimes we see diamonds that look cloudy, hazy, or dull.

The diamond's transparency could be the issue, and various factors might cause it. For example, a diamond will leak light and appear duller and less fiery than it should if the stone is not perfectly sliced. Also, strong fluorescence may cause hazy or greasy diamonds. An unclean diamond may also become milky due to a buildup of film and grime on its facets.


Q: Can a diamond get scratched?

A: Is it possible to scratch a diamond? The quick answer is yes. You can scratch a diamond, but it is not as easy to scratch as other gemstones.

The softer a mineral is, the easier it will scratch. Diamonds are the hardest known natural minerals on the planet. Diamonds rank a 10 on the Mohs hardness scale; all other types of natural minerals rank a 9 or less on the hardness scale.

It's impossible for anything with a hardness lower than a diamond to scratch a diamond. That means that only a diamond can scratch another diamond stone.


Q: What are crushed diamonds?

A: Crushed diamonds look exactly how they sound and have the appearance of broken or crushed ice or glass.

Are they fragmented diamonds? Not at all! They're 100% real, genuine diamonds cut to look like crushed ice.


Q: What are diamond points?

A diamond point, also known as a diamond pointer, is a tiny point made from a diamond.

One diamond carat is equal to 200 milligrams, or 0.2 grams. One diamond point is equal to 1/100th of a carat. So, one diamond pointer equals 2 milligrams or 0.002 grams.


Q: What is a diamond chip?

A: A diamond chip is a small piece of diamond that does not contain facets. Diamond chips are tiny (less than 0.2 carats in weight) and frequently surround a larger center diamond as an accent stone. Since diamond chips are not polished, their surface is not smooth but is rough to the touch.


Q: What is a lab-grown diamond?

A: Lab-grown diamonds, often known as lab-created diamonds, take place in laboratories using cutting-edge technology to replicate the conditions under which diamonds naturally develop when they form in the mantle beneath the earth's crust. Cultivated diamonds consist of carbon atoms arranged in a distinctive diamond crystal structure. Because they consist of the same stuff as genuine diamonds, they have identical optical and chemical properties.


Q: Can a jeweler tell if a diamond is lab-created?

A: Lab-grown diamonds have the same physical characteristics as true-grown diamonds, and your jeweler most likely would be unable to tell the difference. If your jeweler subjects the cultivated diamonds to a diamond detector, they should appear natural. Hence, sending these artificial crystals to a laboratory for testing with advanced equipment is best.


Q: Are lab-grown diamonds valuable?

A: Like natural diamonds, lab-grown diamonds' prices vary according to the Four Cs: color, cut, clarity, and carat. They are, on average, costly. Lab diamond prices are usually about 30-40% less expensive than naturally occurring diamonds. The cost difference is even larger for larger carat weights and fancy diamonds.

When it comes to lab diamond prices, carat weight is an important factor. Although color and clarity can vary during lab production, synthetic diamonds typically have far fewer imperfections than mined diamonds.


Q: Is a synthetic diamond the same thing as a lab-grown diamond?

A: Yes, laboratory-grown diamonds are also called lab-created diamonds, grown diamonds, synthetic diamonds, man-made diamonds, cultivated diamonds, manufactured diamonds, or cultured diamonds.


Q: Are All Lab Diamonds Flawless and Perfect?

A: No, because man-made diamonds are grown by recreating the conditions of nature. Lab-grown diamonds have the same variations of color and clarity that exist in natural diamonds (the 4Cs).


Q: Do lab-created diamonds get cloudy?

A: Lab-grown diamonds have the same qualities as mined diamonds. If these manufactured diamonds fade, it will be for the same reason that mined diamonds do. Although laboratory-grown diamonds may fade, this is only if the diamond's quality is low.


Q: What are composite diamonds?

A: Composite diamonds are tiny diamonds carefully placed together to create a larger-looking diamond. Their setting makes them look like one stone or combined in a design to enhance their attractiveness or glimmer.


Q: Is a composite diamond a real diamond?

A: Yes, composite diamonds are not faux diamonds. Composite diamonds are tiny diamonds that are carefully stacked together to make a more impressive-looking larger stone.


Q: Are diamond testers accurate?

A: One of the most reliable methods to verify a diamond's authenticity is by using a diamond tester. However, you should be aware that a diamond detector using thermal conductivity may mistake a moissanite for a diamond since these two minerals have a similar manner of heat transmission.
