Herkimer Diamonds come only from one specific region near New York in the USA. We only buy from reputable sources, and this (along with our 20 years+ experience in buying, selling and working with crystals) means that ALL the specimens we sell are genuine Herkimers! BUYER BEWARE: you rarely find a cheap Herkimer, and we have seen many examples of fake or misnamed quartz online and in shops over the years, none of which will have the true Herkimer energy and clarity. It is worth remembering that in general Herkimer crystals are short and stubby, with a very bright quality.
In our shop we categorise and price every crystal according to its appearance and condition, and describe all other qualities as accurately and fully as possible. A graded specimens are of the best quality, defined by us as follows:
AAA = the main (normally two) terminations are in perfect or near-perfect condition, and the quartz has an excellent clarity; AA = the main (normally two) terminations are in very good condition, and the quartz has a good to very good clarity; A = the main (normally two) terminations are in relatively good condition, and the quartz has a good clarity.
From a metaphysical point of view Herkimers are one of the best holders and carriers of full spectrum Light, and can powerfully recharge a depleted energy system. They are also very efficient cleansers of negativity, and will offer clarity in all thinking and reasoning processes.
True Herkimer Diamond crystals tend to be stubby and double terminated: many may not appear to be absolutely perfect, but this is because they often grow in clusters and so as a consequence may exhibit indentations (keys) or attachments (seed crystals) when they become separated during extraction: this is perfectly normal (any non-naturally occuring blemishes will be mentioned in the item's description). Additionally some Herkimers may exhibit black or golden-yellow inclusions, or be slightly more cloudy, milky or smoky than others: regardless of this, and regardless of condition, all true Herkimer Diamonds will be harder, brighter and more powerful than most other forms of Quartz.
In fact Herkimers are slightly harder on the Mohs scale than other Clear Quartz crystals (7.5 rather than 7): this means that in general they have a very fine clarity, although it is also possible to find smoky Herkimers, their colour being the result of disseminated anthraxolite (a coal-black mineral). Some may also be slightly coloured yellow by iron or mineral oil materials, and may exhibit other inclusions such as water, pyrite, dolomite or anthraxolite crystals within or on their surface.
