Rough Iolite specimens

These are small rough Iolite specimens, sold in a few different quality grades. While I tend to use the word Iolite, the more correct name for most of these specimens would be Cordierite. Iolite is simply a gem-quality Cordierite.

Iolite is pleochroic and may change colour depending on its orientation. Our grade A specimens show this off best. Iolite specimens from Iceland may be the mineral used as the "Viking sunstone" from the legendary sagas; although this may be Optical Calcite.

  • Grade C is a good mineral sample or ideal for rock tumbling. Nice enough colours, but cloudy. We sell these in 100 gram packets, typically containing 30-50MM pieces.
  • Grade B pieces are a decent quality specimen, good for demonstrating pleochroism. These are sold by their size, not weight.
  • Grade A pieces are nice and clean, possibly suitable cutting cabochons or facets.

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.
