Cotham Marble cabochons for jewellery making or inlay

Cotham Marble is a type of stromatolitic limestone from the area around Bristol, which, when cut and polished, has an interesting effect that looks almost like plants and trees on a landscape.

It is generally too soft to be used for jewellery making - around a 2 or a 3 on the Mohs scale, meaning it scratches very easily. As such, the jewellery must be designed to protect the stone - and ideally it should only be used for earrings or pendants anyway. A better use is as inlay on a wooden box or another object which is not handled often.

If it does get a shallow surface scratch, it can be repolished with a jewellers silver cloth, or some cerium oxide on wet leather. They will be polished before sending out to remove any small scratches from storage.

Our current stock all measure 30x22MM and are cut right here in the UK.

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.
