When mining, many times the Herkimer crystals are still attached to the host rock. They would be damaged if removed, so it's much better to enjoy them as the beautiful crystal matrix specimens they are. For sale on this page are Herkimer Diamonds still attached to their host rock of dolostone matrix. They are exclusive specimens for any crystal or mineral collector.

Dolostone, also referred to as dolomite, is the host rock, or matrix, Herkimer Diamonds are found in. It was formed when the calcite limestone bedrock altered beneath the sea 500 million years ago. Over time, pockets or vugs' formed in the dolostone and the rare quartz crystals grew inside. Dolomite also formed crystals call dog's tooth crystals. Found on some of the matrix specimens for sale, look for small, flat crystals colored whitish to tan to almost pink in the images.

Additionally, many of these vugs' are coated in a micro or sugary crystal, referred to as druse, druze, or 'drusy crystals'. These are tiny crystals that sparkle brilliantly. While it's difficult to get a good image of them, view them through a loop if you have the opportunity. A specimen of just druze is a unique display piece on its own. Used as a 'shelf', they can make a special platform to display one of your favorite mineral specimens.

Herkimer Diamond specimens are not graded, prices are reflective to the quality of the crystals on a particular piece. Please rely on the description notes as well as the images. Note that both inches and mm are used in measurement descriptions.
