Star Sapphires for jewellery making

I hesitate to refer to these as cabochons. Realistically, they are most likely to be used as cabochons for jewellery making - but they do not have a flat back.

Star Sapphires are pieces of Corundum which exhibit asterism - the optical effect which shows a shining star with six rays.

They are not cut with a flat back as this reduces the asterism effect - it is usually deep with a rougher back.

The 'star' is not visible in every lighting situation. It was not visible under my diffused photo lamps, but was visible when lit directly by my mobile phone torch. When viewed in direct sunlight it was very obvious - just finding sunlight in the UK can be a little tricky.


Our current stock includes:

  • #1 - 9.6x8.1x6.4MM - a nice specimen of a blue-grey star Sapphire, believed to be from Burma/Myanmar. This came to me second hand from an older collection, so unfortunately I'm not perfectly sure of the locale.


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.
