Squared. Contemporary. Essential. An unconventional addition to your ring collection.

Inspired by the MK3 building in Berlin, the MK3 SYMMETRIC RING is a cement ring designed with comfort in mind. Linear and geometric, its squared shape is innovative and original yet minimalist.

So light, you’ll forget you put it on. So architectural, you’ll feel an instant urban vibe.

The MK3 SYMMETRIC RING will be shipped in its own gift box with a Certificate of Authenticity and a complimentary drawstring pouch made of organic cotton – the perfect companion for traveling with or storing your wearable sculpture.

      Pro Tip:

      To insert and remove a squared ring effortlessly, remember that the diagonal diameter will be longer than the length of the sides. So, when putting on the ring, turn it slightly on your finger so you can benefit from additional diameter width and slide it on effortlessly over the knuckle. When the ring is in place, you can then turn it a few times to find the best-fitted position.

      When testing the ring for size, make sure to find one which you can both glide on easily and then also turn to set in a comfortable, snuggly fitted position – this will help you avoid choosing one which is too big.
