To properly use a jeweller’s loupe, hold the loupe snugly against your face right in front of your eye. Inspect the specimen for air bubbles. The quartz wont scratch another quartz. Unlike marble and granite, which can be mined,polished, and sold, a quartz countertop has to be manufactured. Clear Quartz is harder than glass so you can test it by trying to cut a piece of glass (something like a glass bottle) with the crystal. Visually inspect the suspect stone. Quartz crystals rate around 7 on the Mohs scale. Some contain bubbles. Quartz has a hardness of 7 on the Mohs scale, meaning that it will easily scratch glass, metals and softer stones. You may need to use a 10x magnifying glass to see better. If you suspect this, check out for bubbles in the stone. This test will not harm the crystal if it is real quartz because glass has a hardness of 5.5 to 6.5. Main: 440-354-2186 Glass … If … You can tell the difference between quartzite and marble by doing the scratch test and the etch test. Test the unknown stone under inspection by trying to scratch a common piece of glass such as a glass bottle with it. Fairport Harbor, OH 44077 How to Tell If You Have a Glass Cuvette. Quartz is 7 on Mohs hardness scale. This is rock-like chunks of crystalline quartz not mixed into other rock. Visually inspect the suspect stone. Check the Hardness. Another way to tell the difference between the two is to touch the objects. Crystal will also feel more smooth and rounded than glass, which will feel more brittle. To properly use a jeweler’s loupe, hold the loupe directly in front of one eye. Test the unknown stone under inspection by trying to scratch a common piece of glass such as a glass bottle. There are many differences between glass and quartz. Pure quartz is high quality and that comes with a higher material cost. Glass rates around 5.5 on the Mohs scale. That means it’s harder than glass and harder than a knife blade. If you have access to a gem tester, measure the thermal conductivity of the suspect stone by pressing the gem tester probe gently but firmly against it. The 10X loupe magnifies an object to appear 10 times larger than actual size. Summary. SiO2 makes up many of the rocks you would find around your house. The primary component of typical beach sand is quartz, or silica (SiO2). Perform your own Mohs hardness test. You can tell the difference between quartzite and marble by doing the scratch test and the etch test. If it takes a lot of effort to scratch the glass, it likely is another piece of glass. Quartz will scratch glass, but I am not sure on the hardness of a steel penknife blade. If the object easily scratches the glass, it probably is quartz crystal. Quartz and glass will create conchoidal surfaces when they break. You can tell that it is crystal if it creates a rainbow prism … They best thing to do to see if it’s a quartz or glass cuvette is to pop it into your spectrophotometer and run a wavelength scan from 200-700 nm. Quartz crystal may contain imperfections, but they are not perfectly round like air bubbles. Press the gem tester probe gently but firmly against the stone. Unlike natural gemstones, glass is an insulator, so it does not conduct heat well at all; consequently, if the indicator needle stops at the lowest reading on the gem tester scale, that one is labelled “Glass.” If the suspect stone is Quartz crystal, however, there is some heat conductivity and the gem tester indicator needle moves to the area labelled “Quartz, Amethyst, Citrine” on the scale. Quartz, on other hand, cooled slowly & does have the geometrically perfect molecular structure that all crystals do. Most sellers, not all, coming from China on eBay mostly likely are fake or enhanced (at least on stones starting under $5 is my experience). In glass you may see round air bubbles. Consider this analysis. Quartz crystals are harder than glass. The presence of bubbles in the stone proves that it is not real quartz crystal. If it is glass, perfectly round air bubbles are usually seen, with or without the aid of a jeweller's 10X loupe. If air bubbles are present, it is glass, not quartz crystal.
