This is my personal favorite crystal to increase self-worth - my ultimate go-to to go with my Rose Quartz. Fancy Jasper is tremendously underutilized and dare I say it... I may even prefer it to Rose Quartz.
 
Jasper strengthens one’s connection to the Earth and the spiritual wisdom and sacredness of life that exists in nature. It encourages one to celebrate moments of beauty in the ordinary and the extraordinary, and to find harmony within the self, and with others.
