Quartz is one of the most popular crystals along with amethyst and clear quartz. It has a calming and soothing energy. It promotes self-love and helps overcome feelings of not being 'good' enough, self-criticism and resentment. It reminds us that when you love yourself and are happy in the moment there is no need for haste. Quartz embraces the one true currency of life, love.
