Another name for this mineral is "Venus hair stone". You can see why - the hair-like rutile crystals (which can be brown, gold, or red) are easy to see in this quartz medium. Quartz has a hardness of 7 while rutile (basically titanium oxide) has a hardness of 6. It's very difficult to get a good polish on this type of stone without pitting.
