For the ultimate collector and Erstwilder aficionado, this limited edition Heirloom Crystal brooch is one of only 200 pieces produced.

Inspired by our original On the Prowl resin design and featuring elegant Czech glass stone detailing set in stirling silver plating, this is a beautiful statement piece unlike anything we've ever produced before!

Designs come complete with edition number 1 - 200 engraving on the reverse side, certificate of authenticity and are packaged in a velvet lined leatherette hinged case with embossed Erstwilder Heirloom detail.


Stretch your legs and arch your back. We can learn so much from our feline friends, so elegant and stoic. Life in the slow lane.

40mm x 48mm (H x W)
To create this special Heirloom Crystal Series piece, the original resin Fan Favourite design has been reimagined by creating a zinc-alloy mould with each Czech glass stone then carefully and securely glued into position by hand. The piece was then plated in either stirling silver or 18k gold. Please visit the ‘Care’ tab for specific instructions.

Jewel brooches

I love the two brooches and my surprise brooch. They are very different to all my other Erstwhile jewellery and the boxes are gorgeous. I’m very happy and can’t wait to wear them 💖

Beautiful Heirloom Pieces

I have two of the heirloom pieces (on the prowl (cat) and the peacock. They arrived promptly and in lovely boxes. I have worn the crystal cat brooch already and I look forward to wearing the peacock. Great for evening wear and very pretty - happy with purchase.

Maria R. (Brisbane, AU)

My cat does this exact pose all the time so I have several 'On the Prowl' versions because they remind me of her. I had an important event to go to when this series launched. I really thought I was going to miss out on this precious girl. We break for lunch and after eating, I jumped on the website to gaze forlornly at my missed beauty. Imagine my surprise when I saw she was not sold out! I think I reloaded the website a good 10 times just to be sure! I was also pleasantly surprised to receive a single digit Edition number too!


Totally gorgeous ! Very happy !
