If you're unsure of your ring size, we recommend visiting our jewelry store for a professional measurement.

You can also measure your ring size at home. Here are a few simple methods to help you do so:

Measure Your Finger

Use a flexible measuring tape or a length of string.
Wrap it around the finger you plan to wear your ring on. If you’re creating a ring stack, consider exactly where on your finger the ring will sit.
If using string, mark the point where the ends meet. Lay the string flat and measure the marked length in millimeters.
Compare your measurement to the size chart to determine your ring size.
If you fall between sizes, choose the larger size for the most comfortable fit.

Measure an Existing Ring

Select a ring that already fits the intended finger comfortably.
Measure the interior diameter of the ring across its widest point in millimeters.
The ring’s diameter in millimeters corresponds to its size. For example, if the ring’s inner diameter is 16 mm, the ring size will be 16.
If the diameter falls between two sizes, for example 18.8 mm, it is recommended to choose the next larger size—in this case, 19.

*Please note: Manual sizing methods—such as measuring your finger at home—can lead to slight inaccuracies. Please read our resizing policy below.

We will work closely with our jewelry designers to make sure that you are satisfied with your purchase.

One-of-a-kind ring composed of hafnium and yellow diamond.

With it’s muted earthy tones, fine-grained hafnium patina creates associations with deserted landscapes and embodies aesthetics of the Japanese wabi-sabi principle. There is the subtle sharpness around the edges of the ring that gives a harmonious finish to it’s imperfectly rustic elegance. Tension setting breathes space between the nuanced ochre ring base and the precious gemstone, allowing a stunning play of light and sparkle. Luminous, excellent cut brilliant juxtaposed by textured, organic tempered hafnium with a polished interior surface.

Hafnium was discovered only in 1923 and is one of Earth’s rarest stable elements – a shiny, silvery metal with hidden potential. Through meticulous artisanal patination techniques, its hidden aesthetic potential is transformed into wearable artworks that explore the expressive language of materials.

Each piece is unique and entirely handcrafted by the artist. The niobium is patinated using a self-developed, undisclosed technique. Traditional metalworking methods are combined with experimental practices. No glue, artificial colouring, or chemicals are used in the process.

Available in custom sizes. Contact us to create your perfect fit.
