Dolomite is not a rare mineral, and it is sometimes overlooked by collectors. However, there are great dolomite specimens! This piece exhibits one of the more interesting and most classic crystal habits of dolomite – the “saddle” habit, where rhombohedral crystals grow together into curved aggregates to create a saddle-like appearance. These light pink crystals are sharp with a pearly lustre, grouped to form a beautiful dolomite specimen. In excellent condition, this is from the John S. White Pennsylvania Collection.
