This page will be a place to see those new discoveries. The discoveries will stay on the page for the given calendar year. At the start of each year the page will begin fresh and the previous year’s discoveries put on a separate webpage. Credit is given to the person who discovers something new in the Herkimer Mining District, along with the right to name the feature.
The Sawtooth Termination:On the bottom of some Herkimer diamonds is an unusual sawtooth termination - slide 2Similar feature found on Herkimer diamond like crystals from Pakistan - shown in slide 3.
Birds Eye Spheres:Birds eye spheres are named so because sometimes the spheres form in the shape of eye with an eye brow. Shown in slide 1. These unique hopper spheres occur in several mines as inclusions and form varied effects as inclusions (see asterisk). The photo data indicate that these form at the contact between liquid hydrocarbon and quartz bearing solutions.
The Hopper Weave Texture
An interwoven mixture of blades, rods, arches, hydrocarbon and often fragments that can take on a jigsaw appearance. Other than the large scale features, such as dimples, this is the most common feature at the quartz-hydrocarbon contact. There is a direct relationship between this texture and crystal frost. See the crystal frost page for more information
