Today we’re going to talk about Growth Interference which is a condition in which a crystal changes shapes as it grows due to the presence of another mineral which acts as an obstruction. These shapes might be squares and triangles, and more often than not, it looks like a buzz saw was taken to the crystal. Sometimes there is a little bit of mineral left in part of the crevasses. Here are some crystals with the →

Last time we talked about Keys and Imprints. There are other ways that triangles and squares may present on crystals. We’ll discuss those here, namely Growth Interference and Record Keepers. Indentations and markings similar to Imprints and Keys also occur but they fall into a different category. Some of these triangular and square-shaped impressions are caused by what is called Growth Interference. Growth Interference happens when another mineral grows during the development of the crystal and →
