Matrix "Herkimer diamond" quartz specimens are rare because the crystals commonly pop off the matrix during collecting, as the matrix is simply very hard. This is a beautiful, bright, eye-catching, doubly-terminated, GEMMY quartz specimen. You can look through the crystal and see the druzy quartz on the matrix under the crystal. Although common in principle, this quality is not. The balance and composition of this piece makes it an elegant thumbnail, worthy of high-quality display in a collection.
