Why you’ll love it

On auction this week, we have two very special rings - two of our most loved models for engagement. Take the chance to bid on rings for both yourself and your partner! 

The Casper Clean Ring is one of our most popular rings for both men and women.

This ring is a real classic! The slightly rounded surface brings a sleek and elegant look.

Casper Clean Ring can be worn to any occasion and on any finger, but is extra popular as an engagement ring. 

This version of the ring has a 4 mm width that looks very well-balanced on any hand. The ring is only 1.3 mm high, making the ring extremely comfortable to wear - even for first-time ring-wearers.

You definitely don’t want to miss out on this one!

This ring has been a showpiece in our Stockholm showroom but is ready to find its new home!

The ring is in a good condition, with some scratches in the gold that can be polished out in the studio at an additional cost (polish is included with size adjustment).  

On auction this week we also have another stunning ring, the Antique Diamond Solitaire Ring. Find it here


Casper Clean Ring can easily be stacked with other rings. 

In the last picture, Cecilia is wearing Casper Clean Ring 4 mm with Tiny Diamond Ring and Mini Brigitte Ring 0.26 CT, as well as Marquise Ring and Round Goldie on the pinky. 


Made in Sweden from 100% recycled 18K Gold

Tip To Win The Auctions

We suggest you wait no longer than 1 minute before the auction ends to place your bid. Many people have the same strategy, and someone else's bid could become the final and winning bid. 

A proxy can help you with this. Setting a proxy amount that is equal to your maximum bid ensures that even when you wait to make your last bid, someone else needs to bid HIGHER than your secret proxy to win – otherwise you will win automatically!

Good luck!
