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 druse 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.

Just like when mining single Herkimers we want every matrix piece to be filled with super quality crystals. Fact is, most matrix, like most single crystals aren't AA grade quality. Sometimes the pocket wasn't large enough to accommodate full formation, so there will be matrix blemishes. Other times the freezing, thawing and other natural occurences will stain or blemish the crystals. Also, when cracking the boulders open to reveal possible vugs, crystals can be broken.
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.

We are happy to now offer larger matrix specimens for sale. Due to the weight and size of these Herkimer specimens they will be shipped USPS Flat Rate Priority Mail. Since additional shipping rates apply, will take advantage of the USPS policy "If it fits, it ships", and sell several specimens together.

Crystals can be ordered via Paypal (credit card) or email (money order). To order with Paypal, simply click the "Add to Cart" button. To order by email, see the Order Information page.
