Herkimer NY 12mmX9mm AAA diamond IN MATRIX Collectors grade A! 2#10oz NEW!SEE MAIN PICTURE PHOTO FOR BEST VIEW OF THE ACTUAL CRYSTAL IN MATRIX ! These Herkimer diamonds are found inside matrix pieces that were started 400+ million years ago, now located at Herkimer diamonds mines in New York, USA. The miniature pocket sometimes contains Herkimer diamonds that are attached to the host rock. These are truly 100% real and heavy and solid.... Do not place on a glass table -it'll scratch it a lot. note on some I have cut off the host rock to provide a smaller and more mobile display, Please see pictures! This is beautiful hand mined quartz diamond from Herkimer NY, This Matrix specimen itself was found inside a rockshelf, these rocks can weigh as much as 500lbs to move, lucky for you! I made it a bit smaller for shipping purposes. :). Dolomite is one of the hardest rocks to try and break....... These are mined by human power only (as per the rules) and all were hand dug by me! so...I will be selling off most of my museum quality AAA+ collection as I descend into retirement over the next few months - Be sure to check out my other Ebay auction listings if this is not the sparkle that speaks to you. A few important notes -1. I ship my matrix crystals inside padded envelope! First Class.2. These are the REAL DEAL with energy, sparkle, luck is included and exclusive ONLY to Herkimer County New York3. If your not 100% satisfied - please let me know - Seriously 100% return.
