#FriezeLondon, one of the world’s most influential contemporary art fairs, is going on now. We're thrilled that four of our esteemed sellers are among the only 160 galleries participating in the fair — @lehmannmaupin, @matthewmarksgallery and @davidaaronarts. Also included in this noteworthy group is @artancient, currently offering this vibrant ammonite fossil, which is over 75 million years old and boasts an arresting iridescence that has us mesmerized.
