Rough Black Obsidian
Specimen pieces of rough Black Obsidian, otherwise known as 'volcanic glass', sold in 100g packets or individually.
You may receive one piece but it might be two or three - depends on our stock at the time.
If you're planning on lapidary usage, please be aware of the risks. Obsidian is a type of glass and extra precautions should be taken when cutting or forming it. The dust can be especially dangerous.
Our 100g packets are all natural broken fragments. The offcut pieces are likely to have at least one cut side/edge cut by a diamond saw, as they are offcuts from sphere manufacture.
The pictures you see here are representative of the products and are usually not the exact item you will receive. Where various grades are available we do try to photograph each grade - but some photographs are still on their way!
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.

I received two respectable-looking pieces of rough obsidian, one a pleasant surprise as it was bigger than I imagined, both perfect for grounding work, which is exactly what I wanted them for. They were exactly as described, with the typical conchoidal fracture and glassy sheen that I expected. It is very rewarding to work with a supplier that knows what they are selling and delivers what they promise!
