The hardness is about 6.5 or 7.
the hardness of Topaz is 8 on moes hardness scale
B. Hardness
No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
Aluminium has a Mohs hardness of 2.75. There are other hardness scales, such as Vickers and Brinell, and these numbers will differ. Each of these scales has a particular field of application.

breast implants
Silicons symbol is Si
Solid.
It has never been stated if she does or doesn't.
Silicon is a solid at room temperature.
Breast implants? Yes she does. She got them when she was in OVW.
Silicon's modern sources mean that where it is found in nature.
Silicon is realatively cheap and is rigid enough, to not break easily.
Silicon the element is used in electronicsto make microchips. Si is a semiconductor.
That is a etch process to make a suede surface which will increase the light absorption.
