Purple Crazy Lace Agate Necklace.  
Crazy Lace Agate is known as the happy stone.  It might just be the crystal you’ve been searching for.  It is usually very brightly coloured stone of greys, browns, black and gold and occasionally pinks and reds and filled with ornate, intricate patterns.  
Crazy lace agate is used for balance and protection. It wards off the evil eye to bring its bearer joy and absorb any emotional pain or turmoil while grounding them.   Metaphysically it is believed to help the wearer get rid of attachments that no longer serve them and encourage clear decision making and enhance creativity.
