You may be surprised by the weight of this ring! What sets this ring apart is that it's made with a whopping five times the amount of silver found in regular rings, ensuring a weighty presence that is second to none. Ångstrom (Å) is the scientific unit used to measure distances between atomic bonds. The geometry of the ring is inspired by electron density models used in chemistry. This ring includes a custom 3D-printed case with felt lining, a soft pouch, and an anti-tarnish pad. Accurate sizing of the ring may vary due to irregular shape. The ring has an open design, so can be adjusted to fit onto a variety of finger sizes for a given size. If you are between sizes, choose round up or down based on whether you want the ring to look small and delicate or large and in charge.
