Trinity Diamond Dog Collar
From £100.00
How to measure your dog's neck
- Wrap a soft tape measure around the middle of your dog's neck, held fairly snug against the fur.
- Note the measurement in inches — this is your dog's neck measurement.
- Choose the size where that measurement falls within the range, ideally towards the smaller end to allow for adjustment.
Example:
If your dog's neck measures 10", choose the 9" to 11" size. This means the collar adjusts between 9 and 11 inches — it does not mean the total length of the collar is 11".
If measuring from an existing collar, measure from the end of the leather to the hole you use — not the total length of the collar. The total length will result in a collar that's too big.
If you're unsure which size is right for your dog, please get in touch — we're happy to help.
- Italian calf leather collar and Swarovski crystal
- 1.25″ wide tapering to a narrower buckle strap
- Choose collar colour from 28 shades
- Stainless steel buckle, D-ring and eyelets
- 8 sizes covering neck sizes from 10.5″ up to 26″
If your dog loves to stand out, the Trinity diamond dog collar is guaranteed to turn heads. The luxury collar is all about the sparkle, with an eye-catching layout of Swarovski crystals that makes it one of the most dazzling in our collection. Choose your crystal combinations for your dog’s collar to create a beautiful, sparkling look.
Here is exactly how the crystals will look on the finished collar:
The Large Crystal (The Centerpiece): This is the main row of big crystals running right through the center of the collar, and you can choose either classic Crystal or the iridescent Crystal AB.
The 1st Crystal Choice (The Top and Bottom Rows): This colour choice is used for the outer framing crystals that sit directly above and below that central main row.
The 2nd Crystal Choice (The In-Between Accents): This colour choice is used for the smaller crystals nestled tightly in between each of the large centre stones.
Which leather colour and crystal combination will you pair together for your dog’s next collar?

Neck measurement — around the middle of the neckWrap a soft tape measure around the middle of the neck, so that it's loosely touching the fur. Don't add any fingers underneath the tape measure. If you don't have a tape measure, a piece of string and a ruler works just as well.

FAQs
How long will my order take?
All collars and leads are made to order. We typically dispatch within 3–7 working days, with Royal Mail Tracked 48 adding 2–3 further working days in the UK. Most orders arrive within 5–10 working days. A dispatch notification is sent by email. If you need a collar by a specific date, contact us before ordering.
Can I exchange my collar if it doesn't fit?
Yes. If the collar doesn't fit when it arrives, you can exchange it for a different size. The most common reason for a poor fit is measuring the total length of an existing collar rather than the dog's neck directly. Full details are on our returns and exchanges page at petiquettecollars.co.uk/returns.
How do I clean a leather dog collar?
A wipe with a damp cloth after muddy walks is usually enough to keep our leather collars looking good. For more stubborn stains, perhaps your dog has been rolling in fox poo, add a small amount of washing up liquid to the damp cloth and gently wipe the affected area. If your dog has been swimming, particularly in the sea, give the collar a wipe with a damp cloth afterwards to remove any residue or salt from the leather.
What leather colours can my collar be made in?
Your leather collar can be made in 28 Italian leather colours: Acorn, Baby Blue, Baby Pink, Black, Bottle Green, Candyfloss, Chianti, Daffodil, Dove, Dusky Pink, Easter Rose, Jaffa, Lime, Madeira Blue, Mushroom, Olive, Peanut Butter, Purple Velvet, Royal Purple, Ruby, School Grey, Shamrock, Signal Blue, Spearmint, Teal, Thistle, White, and Willow.
Are the crystals secure enough for everyday wear?
Every Swarovski crystal is individually secured by hand in our Northumberland workshop. We’ve had customers wearing the same Chaos Theory collar for years of daily walks without losing a stone. If you do ever lose one, get in touch and we’ll do our best to help.
