Optical Calcite Palmstones
Small optical Calcite palmstones, measuring 30-45MM each approximately. Optical Calcite is also known as 'Iceland Spar', although these pieces are from Mexico.
Optical Calcite has an unusual optical property known as birefringence, which splits light into two beams. When viewing text, etc, through a piece of this material, you may 'see double'. This optical property has led to some interesting uses throughout the years - it was possibly used by the Vikings as a form of sun compass on cloudy days, and it was used in World War 2 for precision gun sights.
Optical Calcite is a soft material and is extremely brittle, which means really, it isn't ideal for palmstones. If dropped, it will almost certainly break. If left in a pocket or bag with other objects, it will get scratched. If you want to carry these with you, consider finding a soft bag or carry pouch exclusively for the Calcite.

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.
You can get in touch via our contact page with any questions. 🙂
