Gorgeous little brown, black and grey fossil Stromatolite tumblestones; an ancient layered mound of bacteria which formed the first fossilised life on Earth at around 3.45 Billion years old!
They converted carbon dioxide, sunlight, and sea water into Oxygen, which contributed vastly to the Earths breathable atmosphere.
Some modern day Stromatolites can be found in Shark Bay, Australia; but fossil examples can be found across much of the world, including the UK, Australia, Peru, Bolivia, Russia, and India - bear in mind, when these mounds grew, most of the Earths surface was underwater.
These pieces make a great decorative stone and talking point; whether you're a fan of fossils or tumblestones!

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.
What are tumblestones?
Tumblestones are stones that have been put in spinning barrels with an abrasive compound for weeks or months. This slowly rounds off the rough rock and corners – the stones are then cleaned, and placed with a less abrasive grit. This happens several times until the stones are placed into a barrel with a polishing compound for their final polish.
