Discovered 2023 A.D. – Rock N Roll Mine, Middleville, Herkimer County, New York.
The Donut Pocket is a remarkable discovery of high-clarity AAA-grade Herkimer diamonds, unearthed in the Middleville region, known for producing some of the finest Herkimer quartz crystals in the world. These crystals, particularly notable for their pristine clarity and near-perfect formation, are rare and highly sought after by collectors and crystal enthusiasts alike.
Herkimer diamonds are a unique variety of quartz crystals found in the Herkimer County area of New York State, USA. Despite the name “diamond,” they are not actually diamonds but rather double-terminated quartz crystals. The term “diamond” arises because of their diamond-like shape and exceptional clarity.
These quartz crystals formed millions of years ago, during the Silurian period, in hydrothermal veins within limestone deposits. The formation process is unusual and complex: hot water filled these cavities and created a mineral-rich environment. Over time, the water cooled and the minerals, particularly silica, began crystallizing in the cavities. What makes Herkimer diamonds unique is their double-terminated nature, meaning they grow naturally at both ends without a point of attachment, giving them an unusual and striking aesthetic.
One of the most intriguing features of Herkimer diamonds, especially those from the Donut Pocket, is their perfect molecular stacking. Quartz is a crystal form of silicon dioxide, and the structure of Herkimer diamonds exhibits perfect symmetry in their molecular arrangement, contributing to their exceptional clarity and sparkle. The molecules of silica are perfectly aligned in a way that maximizes the internal reflection of light, giving the crystal its trademark brilliance.
The clarity and precision of their formation also allow these Herkimer diamonds to showcase a high degree of transparency, often approaching the visual quality of a high-grade diamond. The nearly flawless nature of the Donut Pocket’s specimens speaks to the ideal crystallization conditions that were present when they formed.
