A heavy, superiorly comfortable half donut band, hand-carved and cast in sterling silver (also available in 18k gold, 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 18k gold.
Approximately 9 grams, depending on size.
