The smaller jewelry size Herkimer Diamond crystals are the hardest to accumulate in serious quantity. In A grade to AA grade, They make up maybe 3% of all the crystals that come out of the ground. The run generally from 2mm to 20mm range, crystals this quality over 1" are very rare. We wait patiently throughout the year for our independent miners to supply us , the work that goes into sorting alone is hours of cross eyed fun. Not to mention how hard mining is by hand. These crystals usually start to form inclusions over 10mm to 12mm or apporx 1/2"
Most Herkimer Diamonds are single crystals, with occasional "rider" or "penetrating" crystal attached, these usually run up in size to around 3", all though places in St. Johnsville & Fonda NY are producing huge crystals 6" - 10" in size, these of course are not water clear, and are full of gas inclusions in this size, but nonetheless, massive crystals for this quartz variety.
About Herkimer Clusters - almost ALL Clusters - Multiple Crystals together - have 1 or more crystals that have been professionally reconstructed using special epoxy. (Not repaired - these crystals only go together one way , "key marks" and almost all of them fall apart in the pockets over 500 million years since their creation. The best clusters in the world have been reconstructed as well). If it says Natural Cluster in the title then that has not been reconstructed and is something rare indeed.
Skeletal Crystals are interrupted growth, layer by layer they grew and regrew forming these etched faces and elestial features. These are rare, especially for Middleville where the 2 main mines are located. Scepters also occur, having long black stems, and primarily formed in the Little Falls region and are seldom seen in other locations.
These are a 7.5 hardness, slightly harder than normal quartz.
These beautiful double terminated water clear crystals are some of the best Quartz Crystals in the world. Direct from the source right here in upstate NY. Thank you for choosing IVC
