A heavy, superiorly comfortable half donut band, hand-carved and cast in 18k yellow gold (also available in sterling silver, or other gold karats and platinum by request). More substantial than a classic half round (more like a 3/4 round). A donut, if you walled up the interior just a bit to hug your finger and not stick out quite so much. Simple, but also not. Really good. Also available in sterling silver.
Approximately 13 grams, depending on size.
