XYZ Tectum Ring

£4,599

A sublime elevation of traditional forms, this 18-karat gold masterpiece positions a radiant baguette diamond asymmetrically along its commanding apex—like the crowning ridge of an architectural marvel.

The intentional asymmetry creates dynamic tension, challenging conventional balance while celebrating the unpredictable beauty found in natural mineral formations. Each hand-carved parallel striation tells the story of crystal growth, meticulously etched to capture light in unexpected ways.

When adorning the hand, this perfectly imperfect gold solitaire ring becomes a personal sanctuary. The Tectum is a quintessential treasure for the connoisseur who appreciates the contemplative dialogue between refined structure and natural evolution.

    Size guide

    Rings are not only worn on the body but almost integrate with it through motion and gesture. Therefore, choosing the correct ring size and style is essential to ensure its comfortable fit. There are many size conversions adopted worldwide, and the same-sized ring with a wider band will feel closer to the finger than one with a delicate band design. For the best fit and feel supporting wearability, please refer to the conversion chart below or email info@agatakarwowska.com for personalised advice.
