![]() They don’t have any inclusions and are blemishes visible under up to 10x magnification.įlawless diamonds are extremely rare. As expected, flawless diamonds have the best clarity. The diamond clarity scale consists of FL (flawless), IF (internally flawless), VVS1-VVS2 (very very slightly included), VS1-VS2 (very slightly included), SI1-SI2 (slightly included), and I1-I3 (included). Some amethyst and citrine are Type 2 gemstones because they have minor visible inclusions. Type 1 gemstones are usually eye clean, which means they don’t have inclusions visible to the naked eye. Smoky quartz, citrine, and amethyst have Type 1 clarity. Not all varieties of quartz fall under the same category. Colored gemstones have their own clarity scale in which there are three types: Type 1, Type 2, and Type 3. For example, people like “silk” in sapphire and “horsetail inclusions” in demantoid garnet. However, in other gemstones, inclusions are sometimes a desirable trait in the stone. Clear diamonds that are free of inclusions are more valuable due to greater clarity. Quartz and diamond are graded on different clarity grading scales. Difference in Clarity Classic Floating Diamond Ring (Image Source: Pinterest) It also has great heat resistance and electrical properties, resulting in its use in electronics. ![]() Quartz is chemically inert with most substances. Thus, although quartz is one of the more common and less expensive gemstones, it’s still good for jewelry. Another use for quartz is in counter tops. A variety of quartz, novaculite, is often used for sharpening knives. 7 is about as low as a gemstone can be for use in jewelry. Without argument, between quartz vs diamond, diamond has better hardness. On the Mohs scale of hardness, quartz ranks a 7 and diamond is a 10. Ideal and super ideal cut diamonds have the greatest brilliance. Diamonds have so much brilliance that even the fair cut grade has decent brilliance. Gemstones with good cuts have better brilliance than those with poor cuts. The two beams travel at a different speed and on a different path in the gem.Ĭut can influence the brilliance of a diamond. Double refraction is when light splits into two beams upon entering the gemstone. Another difference between quartz vs diamond is diamond is singly refractive whereas quartz is doubly refractive. The higher a gemstone’s refractive index, the more brilliance it has. Its refractive index is 2.42, compared to quartz’s refractive index of 1.54-1.55. Difference in Brilliance Image Source: īetween quartz vs diamond, diamond has better brilliance. ![]() Diamonds with very good to excellent cut on the grading scale have the best sparkle. Quality of cut is an important factor in determining how much the diamond sparkles. Although diamond in general has great sparkle, some diamonds have better sparkle than others. Quartz reflects light through its natural luster, allowing it to give an attractive twinkle effect. Difference in Sparkleīetween quartz vs diamond, diamond is known for excellent sparkle. Colored diamonds are more valuable than white diamonds because they occur far less frequently in nature. That may lead you to believe colored diamonds are less valuable than clear diamonds, but the opposite is true. Color in a diamond results from impurities or structural defects. However, the properties of a colored diamond are slightly different than clear diamond. But today scientists look at the mineral’s microstructure too.ĭiamond is similar in that people are usually referring to the clear variety unless they specify its color. Historically, quartz was differentiated based on color. What we call quartz is the clear variety. For instance, pink quartz is called rose quartz. Colored quartz goes by different names depending on its color. Quartz comes in many different colors like pink, yellow, blue, and purple. Below, we will explain the similarities and differences between quartz vs diamond, including color, sparkle, brilliance, hardness, clarity, cut, and price. However, you will want something more durable for an engagement ring. If you want jewelry with clear gems that sparkle, then quartz is an acceptable choice. ![]() Many people wonder if quartz is a suitable diamond substitute because of its clear color.
