It can be hard to predict when you're going to feel like being mischievous, am I right?  It can just come upon you with no warning at all.  So better to be prepared all the time, just in case.  After all, you want to be dressed for the occasion -- and this arm candy of orchid pink quartz with faceted carnelian rondelles is just the ticket.  Even if you decide to be good, after all.  It goes both ways.
