Herkimer Quartz 'Diamond' specimens

Small Quartz crystals from Herkimer, New York, which are given the trade name 'Herkimer Diamonds'.

It should be made very clear that these are Quartz and not Diamonds in any way. Due to their tendency to be extremely clear, and to form into unusual crystalline shapes, these are very popular with collectors.

They often have dual terminations - that is a Quartz point with a 'point' at each end; but not every time.

Our current stock includes:

  • #1 - 29x28x19.5MM. Nice clear piece with plenty of unusual shapes; some unidentified inclusions.
  • #2 - a 20.3x17.5x15.5MM piece with one termination, still sitting on some of its original matrix. Not technically a Herkimer Diamond, as it is not dual terminated. Interesting striations on the crystals.

The photographs on the listing are of the exact piece you see here.

Frequently asked questions and delivery information

How do we grade stones?

There is no overall universal grading system for the majority of our products. As such, the grades we use are internal only. They simply refer to higher and lower qualities, but they may be entirely different grades to other websites. C grade pieces are of lower quality than B grade, which is lower than A grade.


How does our ordering and delivery process work?

You place an order via the website. When it’s been picked and packed, your order will be marked as completed and dropped off at our local post office. We have an account with the post office called a “Drop and Go” account, which allows the post office staff to process our parcels when they have free time, rather than me queuing up and delaying everyone else.

I get tracking information etc online when this has been completed. I typically do not send tracking information to customers unless they request it – but if you’ve requested tracked postage, it has been sent tracked! If you have any worries or concerns about your parcel being delayed please feel free to get in touch and I’ll send the tracking info over! We also get delivery confirmations for parcels over 25MM thick by default.


How do international orders work?

After Brexit, with the UK leaving the European Union, certain things have changed with regards to international orders. European Union customers will now likely be liable to pay the same amount of import VAT as any other international customers. You will be responsible for any customs and import fees.


I’d like to return my order for a refund.

No problem at all – just get in touch and we’ll arrange it. You can read our full returns policy here.


What payment methods do you accept?

I can accept Paypal, Stripe, cheque, and direct bank transfers. Paypal and Stripe will both allow you to pay with credit and debit cards.
