Celtic Diamond Collar

Inspired by the intricate knot work of the magnificent Book of Kells, our Celtic Diamond Collar evokes the splendour of this ancient artwork.

Celtic Diamonds are particularly suitable for dogs with short, broad necks, like Staffordshire Bull Terriers and similar breeds, designed so the collar won’t slip over their head.




A hard-wearing design, the crystals are set in their own bezel, like a piece of fine jewellry, which are permanently secured right through the depth of the hide, making it virtually impossible for your dog to lose a crystal.

Each piece comes with a written guarantee backed by our lifetime repair service in the unlikely event it should ever be required.

Choose a collar size that will fit your dog close to the middle of the fitting.

If your dog’s measurement is close to the tightest or loosest fitting, then please select the nearest collar size and add a customized option, entering the size required taken according to the How to Measure instructions below.

To ensure you order the correct collar size please use this easy to follow guide:

1) Using your dog’s own collar, place it around your dog’s neck and note which hole is the comfortable fit.

2) Take the collar off and lay it flat.

3) Use a taut tape measure or ruler: start your measurement at the top of the buckle and measure straight down to the hole you noted.

This measurement tells you exactly the collar size your dog needs.

Compare this measurement to the size chart and select the size that will provide a fitting near the middle.

If your dog’s measurement is on, or near, the tightest or loosest hole then select the collar size that will be closest to your dog’s measurement and add a customized option to get a perfect fit.

As an example, this diagram shows that the dog comfortably wears this collar on the second to the last hole. The measurement is taken from the top of the buckle to that hole.


If you select a custom fit with 5 holes we will make the sizing so that this measurement fits the middle hole of 5.

Alternatively, if your dog is full-grown, you can choose to have just 3 holes, with the comfortable fit in the middle and extra crystal covering the space where the other two holes would normally be maximizing the amount of crystal that is seen.

If you are unsure of the size you require, please email us a photo of your dog’s collar with a taut tape measure or ruler next to it as described above – we would be happy to advise you.

Please provide your dog’s correct collar measurement taken according to our instructions. The entire length of the collar or any other measurement is irrelevant. We will endeavour to make every custom order to your exact measurement, however due to the inherent properties of natural leather, there may be some slight, unavoidable discrepancy.
