A heartstone is a heart-shaped rock. Many different types of rocks can be heartstones; all that matters is the shape. Many heartstones form naturally through tricks of weathering; others are artificially chiseled and polished into a heart shape.
I often look for heartstones when walking– along a beach, a woodland path, or even a driveway. Whenever I find a heartstone, I think fondly of a bookstore called “Heartstone Books” that I used to visit in Putney, Vermont. Long before I ever studied geology in a formal manner, I used to enjoy looking at this bookstore’s collection of heartstone rocks and was amazed at how many different types of rocks– different colors and textures and sizes– could become heartstones.
I am currently traveling and cannot take photos of my own heartstones, so below are a few heartstone pictures that I’ve scavenged from the interwebs.
Happy Valentine’s Day, everyone!
