2.3 cm across. Just a razor sharp, gemmy, transparent mandarin-orange garnet crystal...incredible color and transparency in person, in fact for the size one of the most gemmy crystals in the lot! It has some minute black inclusions, but they do not detract so much in person - in the photo you are looking through a 1-inch crystal out the back, so it adds up more in the camera's eye than in the human eye. Complete all around all faces, except for minor contact on the two bottom faces only.
