Would amethyst glass scratch and / or quartz?
I try to understand if I got this pendant is really nice quartz or glass. I have a real piece of amethyst with jagged edges, and I wonder if I can use to find out.
Yes Amethyst is a type of quartz is harder than glass, so it will scratch the glass since it is a variety of quartz, it is equally difficult other types of quartz and is the scratching and a mineral can scratch any other mineral that is equal or greater hardness
