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.

Resizing Policy

We will work closely with our jewelry designers to make sure that you are satisfied with your purchase. Items can be altered according to your specifications but please note that additional fees and additional delivery time may apply. We cannot, however, offer resizing on a few fine jewellery designs. Please contact us if you have any questions about a particular ring.

Rings made to order

If you cannot find a ring of your size and/or a ring you like cannot be resized, sometimes it’s possible to make a new ring if requested. Therefore, you are welcome to get in touch to discuss your requirements and we’ll do our best to accommodate them.

One-of-a-kind ring composed of niobium and a white diamond.

This minimalist diamond ring explores form and function through a modern aesthetic that combines visual elegance with harmonious proportions. The tension setting creates space between the matte anthracite ring base and the precious gemstone, allowing for a striking play of light and brilliance. A geometric, luminous, perfectly cut brilliant diamond is juxtaposed with textured, organic, tempered niobium featuring a polished interior surface.

All white diamonds used by ASR JWLS are VS clarity, F+ colour, excellent cut, and certified by the National Assay Office of Lithuania.

Niobium is a rare, technology-critical metal valued for its strength, lightness, and unique properties used in superconductors, electronics, and optics. Through meticulous artisanal patination techniques, the material is transformed into wearable artworks that reveal its hidden beauty and expressive potential. Niobium is also comparatively lightweight and comfortable for everyday wear.

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.
