Diamond and Quartz

The Difference Between Diamond and Quartz Gemstones

There is a significant variation in hardness between diamond and Quartz. Diamonds are significantly more complex than Quartz. We can distinguish between these minerals based on their chemical features, application, price, and demand. Crystalline Quartz is formed of silicon dioxide. Diamond has the chemical formula C and is composed of carbons, whereas Quartz has the chemical formula SiO2 and is composed of silicon dioxide.

The diamond’s hue is either white or colorless in its purest form. Diamonds can be found in several colors, including orange, brown, yellow, and traditional white tones. In addition to blue, purple, green, and deep red diamonds, there are also rare diamonds that can be discovered in different colors. They have a white stripe and have a hardness of 10 MOH on the MOH scale. On the other hand, Quartz can be found in a range of colors, including white, brown, purple, and multicolored, in addition to the colorless type of the mineral. Quartz has a white streak, and its hardness on the MOH scale is a seven.

The Difference Between Diamond and Quartz Gemstones

Diamond crystals can be either cubic or spherical, but quartz crystals can take on a variety of unique shapes. Quartz is hexagonal, whereas diamonds are isometric. On the transparency scale from transparent to opaque, they are both transparent. Diamond has a specific gravity of 3.1-3.5, whereas Quartz has a specific gravity of 2.6″ 2.7. Unlike diamond, which is adamantine and has a shiny luster, Quartz is vitreous and can be either glossy or dull in appearance, depending on the variety of crystals used. Quartz has no discernible cleavage, but the diamond has one or all sides, an octahedral structure. Quartz and diamond tenacity is becoming increasingly fragile.

Silica, Crystalline Quartz (also known as Macrocrystalline Quartz), and Alpha Quartz (also known as High Quartz) are various names for Quartz. There are hundreds of quartz variations, including Microcrystalline Chalcedony, Citrine, Amethyst, Rose Quartz, Rock Crystal, Smoky Quartz, Milky Quartz, Rutilated Quartz, and Aventurine. The Ballas, Bort, Carbonado, Black Diamond, and Hexagonal Diamond, are all diamond variations.

Quartz is the second most abundant mineral on the planet, but diamond is the hardest substance known to man. Of all minerals, diamond is the best heat conductor and has the highest refractive index of any. They are frigid to the touch and can retain their heat for an extended period. Quartz is also available in the form of Blue Rock Crystals, which have been chemically colored.

Quartz has many significant applications, including electronic applications employed as an oscillator and abrasive. It is also utilized in the ceramics industry, computers, the soap industry, and the trading sector. Diamond is the ultimate symbol of brilliance, nobility, and durability, and it is most commonly found in the jewelry sector. Thermal insulation, abrasives, and applications in electronics and optics are just a few of the applications for diamonds. Some of the characteristics that separate the two minerals are as follows:


It is critical to understand that Quartz is available in various colors. Quartz comes in a variety of colors, each with its name. Amethyst, for example, is a purple quartz crystal with a transparent center. On the other hand, Rose quartz is the only stone that is pink.

Diamonds can be found in a variety of colors. This, however, is owing to structural flaws and impurities in the material. Diamond in its purest form is translucent. Because of this, color can play a role in determining the difference between diamond and Quartz.


Sparkle is one of the characteristics that you would look for in a proposal ring. That’s correct. The diamond, on the other hand, glows more than Quartz. Quartz has an inherent shine that allows it to reflect light, and it provides a gorgeous twinkling that you might mistake for sparkling at first glance.

The cut of the diamond, on the other hand, has an impact on the shine of the diamond. Diamonds with superb cuts offer a more significant amount of shine than other diamonds. Both sparkle and twinkle are beautiful, but only if you understand the difference between the two.


Diamond is more complicated than Quartz on the Mohs scale of hardness, which measures how hard a material is. Compared to diamond, Quartz has a hardness of 7, and it is more complicated than diamond. As a result, the diamond is the most challenging gemstone to work with.

If you choose jewelry that will last a long time, diamond-made jewelry is ideal. On the other hand, Quartz can be used to create beautiful jewelry that is not too pricey.


Another element to consider is their level of brilliance in the field. The power to refract is what we may define as brilliance. As a result, the highly ranked on the refractive index are the ones that have the most brilliance.

Diamond has a refractive index of 2.42, which is very high. On the other hand, Quartz has a refractive index of 1.55, which makes it a good choice for optical applications. As a result, diamond outshines Quartz in terms of radiance and luster. Do you like to wear eye-catching jewelry? For you, diamond jewelry will be the best option available.


To get a unique shape, each mineral is sliced. Surprisingly, each cut has its own set of characteristics. Quartz is also available in various additional cuts, such as CT, AT, and SC. AT-cut quartz is used in a variety of electrical equipment, including calculators.

On the other hand, Diamonds are available in a variety of shapes, including princess, cushion, and oval. The brightness of a diamond is determined by the way it is cut. In this instance, well-cut diamonds exhibit a high degree of brilliance.


Another property that distinguishes these two minerals is this. The clarity of a gemstone is determined by the inclusions seen on it. As a result, the lower the number of inclusions, the greater the transparency.

There are three different forms of clarity: type one, type two, and type three. Depending on the nature of Quartz, it is divided into several groups. Citrine, for example, has type 1 clarity, although some amethyst has type 2.

The clarity scale for diamonds is different. It comprises three parts: flawless (FL), VVS 1, and VVS 2. The most acceptable clarity is seen in flawless diamonds, and the high clarity is because no inclusions can be seen even under close inspection.

Perfect diamonds, on the other hand, are rare. Any diamond with a clarity rating of VS1 or higher has clear clarity, and they have no inclusions that can be seen with the naked eye. You can notice some inclusions in VS2 diamonds if you look closely enough.


Ever heard the adage “cheap is expensive?” Do you know what I’m talking about? When comparing the prices of Quartz and diamond, it is clear that diamond is the more expensive of the two. When compared to quartz jewelry, diamond jewelry is more expensive.

The disparity in pricing corresponds to the disparity in quality. Things made of diamond are of higher quality than items made of Quartz. You are likely to be attracted to inexpensive pricing, but you will replace your things more frequently.

What is it About Quartz that Makes it so Special?

Quartz stands out from the rest of the minerals in several ways. According to the records, the material is the fourth-strongest substance on the planet. However, hardness is not the only characteristic that distinguishes it from other materials. Are you interested in learning more about why you should explore this mineral? What distinguishes it is as follows:

Durability: When Quartz is coupled with resins, it generates the most complex surface on slabs, ensuring long-term durability. This can be attributed to the fact that it is challenging, and quartz surfaces are hygienic and exceptionally durable.

Abundance: Quartz is the most abundant mineral on the planet, out of all the minerals. The abundance is the product of a straightforward mining procedure. Because Quartz is readily available in small chunks, the mining procedure is simplified.

What Makes Diamonds so Special?

Many people consider diamonds the most valuable and distinctive gemstone on the planet. It is critical to emphasize that no two diamonds are alike in their form and size. As a result, one characteristic that distinguishes diamonds is their uniqueness. In addition, they have an inner fire that we find appealing to be around.

Diamante is the most challenging mineral to work with that you will ever encounter. The hardness of the material allows it to conduct thermal energy 100 times more effectively than copper does. As a result, diamonds are highly valued and utilized by individuals in the energy industry.

Is it Possible for Quartz to be Mistaken for Diamonds?

Test for Hardness

Diamonds are capable of scratching every other mineral, but only diamonds are capable of scratching other diamonds. Quartz, the mineral most likely to be mistaken for diamonds in uncut rough form, has a hardness rating of 7 on the Mohs Scale of hardness.

Is Quartz or Diamond More Expensive?

The most significant distinction between Quartz and diamond.

Quartz is a lot less expensive than diamond, for example. Quartz is found in various shapes, while diamond is found in cubic or round shapes. The chemical designation Sio2 knows Quartz, and diamond is known by the chemical name C. Quartz is employed in technological devices. In contrast, diamonds are used in jewelry and other decorative items.

Quartz Vs. Diamond: Which is Better?

Diamond is the hardest known substance on Earth, while Quartz is the second most prevalent mineral. Diamond has the highest refractive index of all minerals and is the best heat conductor; and they are frigid to the touch and can stay hot for an extended period.

It may be challenging to choose between the items made from the two minerals. Diamond provides both superior quality and a higher rate. On the other hand, Quartz is known for producing low-quality things that are not long-lasting. We may conclude that each mineral performs best when appropriately applied.

It would be impossible to find a substitute for this mineral in some cases. For example, diamond is the only material used to make cutting tools. On the other hand, Quartz is essential in the production of timepieces such as watches and wall clocks.


In certain aspects, Quartz and diamond are similar, although the two stones have distinct characteristics. For example, they can differ in complexity, brilliance, color, glitter, cut, and pricing. Not only do their densities and crystal structures differ, but so do the majority of their physical characteristics.

In the case of a choice between the two minerals, the diamond appears like the superior choice. Because of its hardness, it can withstand scratching and abrasion. Furthermore, it is the most complex natural material found anywhere on the planet.
