Everyone seems obsessed with crystals lately, but if you don’t quite get what the fuss is about, it’s OK. Earth Speaks has you covered with a healing crystals workshop on Wednesday. From 6 to 8 pm, energy healer Jissel Ravelo will take over the Brooklyn Heights shop to walk you through all the basics, from choosing a crystal to making use of its healing properties to proper care and storage. You’ll leave ready to incorporate crystals into your daily life, armed with a set of your own. Each $38 ticket includes seven healing stones, each connected to one of the seven chakras. It’s the perfect way to recenter your week.
