A hammer. You would break it off and flatten out the gold which is malleable from the fragile quartz.
If you rubbed a mineral of hardness 7.5 against a piece of quartz, which has a hardness of 7, you would expect the harder mineral to scratch the quartz. The mineral with a hardness of 7.5 would leave a mark or scratch on the quartz surface, demonstrating the principle that harder materials can scratch softer ones. However, quartz would not be able to scratch the harder mineral in this scenario.

yes it will me magnetic it will separate anything metal or iron.
This would be quartz.
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
Quartz
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Quartz because its harder than calcite and the quartz in thicker.
The best tool - would be a pair of small tweezers. That would probably help you remove the piece stuck in the socket.
When raisins are stuck together, they can be pried apart manually (which is to say, you can do it with your fingers). If you would like to make them less sticky, you can coat them with flour.
A non-metallic mineral such as quartz or calcite.
The best anwser would be A, that they contain quartz.
