LADY GAGA loves QUARTZ CRYSTALS and so do we! If you've seen the video and pictures of Gaga surrounded by crystals, holding them while Naked, or lying naked on a large quartz point, you'll want to do what she's doing, but first you have to find someplace that sells natural quartz crystals, and preferably a lot of them.

Silicon Dioxide (known as Quartz) is not the hardest mineral, the hardest mineral is an allotrope of carbon called diamond. Quartz is only the 7th hardest mineral.
Quartz- hardness 7 on Mohs Scale. (Calcite: 3, galena 2.5, talc 1)
The diamond is the hardest mineral and is the state mineral of Arkansas.
No. Quartz is harder than steel (based on the Mohs scale of mineral hardness), and diamond is THE hardest mineral.
Talc - softest Gypsum Calcite Fluorite Apatite Orthoclase feldspar Quartz Topaz Corundum Diamond -hardest
apatite will not scratch quartz topaz calcite or corundum
Using the geological Moh's scale of hardness of minerals: 1 - Talc 2 - Gypsum 3 - Calcite 4 - Fluorite 5 - Apatite 6 - Feldspar 7 - Quartz 8 - Topaz 9 - Corundum 10 - Diamond
Quartz.
A non-metallic mineral such as quartz or calcite.
Well the mohs hardness scale, goes upwarda by 1 everytime and diamond (10) being the hardest is Talc Gypsum Calcite Flurite Appatite Fieldspat Quartz Topaz Corundum Diamond
Hi, Diamond has a hardness of 10, quartz is between 7 and 8 depending on what quartzite mineral . So Diamond is the hardest.
